Feritin normalno opada kako trudnoća napreduje, ali nizak rezultat i dalje može otkriti iscrpljene zalihe željeza prije nego što hemoglobin padne. Tromjesečje, markeri upale i vaša kompletna krvna slika mijenjaju tumačenje.

⚡ Kratak sažetak v1.0 —
  1. Prag trudnoće: Rezultat feritina ispod 30 ng/mL (µg/L) se često smatra iscrpljivanjem željeza u trudnoći, čak i kada hemoglobin ostaje normalan.
  2. WHO granična vrijednost: Ferritin ispod 15 ng/mL ukazuje na nedostatak željeza kod naizgled zdravih odraslih osoba, ali stručnjaci za trudnoću često djeluju ranije.
  3. Očekivana promjena: Feritin obično opada od prvog do trećeg tromjesečja jer se volumen plazme povećava i rastu potrebe fetusa i posteljice za željezom.
  4. Definicija anemije: Hemoglobin ispod 110 g/L u prvom ili trećem trimestru, ili ispod 105 g/L u drugom trimestru, ispunjava WHO kriterije za anemiju u trudnoći.
  5. Korisni prateći testovi: Feritin treba čitati zajedno sa hemoglobinom, MCV, saturacijom transferina, CRP, i ponekad rastvorljivim transferinskim receptorom.
  6. Ponovno testiranje: Nakon početka oralne suplementacije željezom, kliničari obično ponavljaju kompletnu krvnu sliku u 2 do 4 sedmice i feritin kasnije, ovisno o simptomima i gestacijskoj dobi.
  7. Hitni simptomi: Bol u grudima, nesvjestica, nedostatak daha u mirovanju, obilno vaginalno krvarenje, ili smanjeni fetalni pokreti zahtijevaju hitnu procjenu u porodiljstvu, a ne rutinsko ponovno testiranje feritina.
  8. Napomena o visokom feritinu: Feritin može porasti kod infekcije, oštećenja jetre, gojaznosti i upalnih bolesti, tako da normalan ili visok rezultat ne dokazuje uvijek adekvatno iskoristivo željezo.

Kako danas procijeniti rezultat feritina u trudnoći

A normalni raspon za feritin na laboratorijskom nalazu za trudnice može biti pogrešno tumačen tokom trudnoće. U praktičnoj akušerskoj njezi, feritin ispod 30 ng/mL (µg/L) obično signalizira niske zalihe željeza i zaslužuje razgovor sa vašom babicom ili kliničarem za akušerstvo, dok vrijednosti od 30 ng/mL ili više su više ohrabrujuće ako CRP nije povišen i krvna slika je stabilna.

Feritin je oblik željeza koji tijelo skladišti, a ne direktno mjerenje željeza koje cirkuliše tog jutra. Trudnoća povećava volumen plazme za otprilike 40% do 50%, pa hemoglobin i hematokrit opadaju zbog razrjeđenja; feritin također opada jer se skladišteno željezo koristi. Nizak feritin stoga nije samo “trudničko razrjeđenje”. Obično je to iscrpljena rezerva. Pogledajte naš Vodič za proučavanje željeza za srodne markere.

Smjernice Britanskog društva za hematologiju koriste feritin ispod 30 µg/L kao okidač za ponudu suplementacije željezom u trudnoći, posebno od 28. sedmice nadalje (Pavord et al., 2020). Niži dijagnostički prag WHO-a od 15 µg/L je visoko specifičan, ali čekanje na 15 može propustiti klinički korisni prozor prevencije. Ta dva praga nisu neslaganje o biologiji; služe različitim kliničkim ciljevima.

Od 30. augusta 2026. godine, ne bih sudio o rezultatu feritina u trudnoći samo na osnovu odraslog ženskog raspona laboratorije. Kantesti je AI analizator krvi koji stavlja feritin pored gestacijske dobi, hemoglobina, MCV, CRP, i prethodnih rezultata, jer obrazac nam govori mnogo više od jedne istaknute zastavice.

Feritin u trudnoći po tromjesečjima: praktične referentne trake

Feritin obično opada tokom trudnoće, ali ne postoji jedinstveni trimestralni “normalni” interval prihvaćen od svake laboratorije. Pragmatično kliničko čitanje je da 30 ng/mL ili iznad sugerira razuman nivo zaliha, 15 do 29 ng/mL sugerira iscrpljene ili granične zalihe, i ispod 15 ng/mL snažno podržava nedostatak željeza kada nema upale.

Normal range for ferritin interpreted across three pregnancy stages in a clinical laboratory scene
Slika 2: Sekvencijalni laboratorijski uzorci predstavljaju očekivani pad zaliha željeza tokom trudnoće.

Koristan radni raspon u prvom trimestru je otprilike 20 do 150 ng/mL, ali gornja široka granica odražava upalu, kao i zalihe željeza. Do drugog i trećeg trimestra, mnoge zdrave pacijentice imaju niže vrijednosti, često 10 do 60 ng/mL. Ključno kliničko pitanje nije da li vrijednost odgovara širokom intervalu populacije; već da li se približava iscrpljenosti željeza dok potražnja za željezom ubrzava.

Feritin od 22 ng/mL u 10 sedmici i isti rezultat u 34 sedmici nisu identične situacije. U 10 sedmici, postoji vrijeme za postepeno obnavljanje zaliha; u 34 sedmici, kombinacija niske rezerve i hemoglobina od 104 g/L često opravdava planiranje hitnog liječenja. Zato se crvene zastavice iz krvnih testova u trudnoći tumače uzimajući u obzir gestacijsko vrijeme.

Neke evropske službe za porođaj koriste prag feritina od 30 µg/L tokom cijele trudnoće, dok druge rezervišu oznaku “nedostatak” za vrijednosti ispod 15 µg/L. Klinički stav dr. Thomasa Kleina je da oba mogu biti korisna: ispod 15 potvrđuje značajno iscrpljenje, dok 15 do 29 identifikuje pacijentice koje mogu postati anemične prije porođaja.

Je li vaš feritin nizak zbog normalnog razrjeđivanja ili pravog iscrpljivanja željeza?

Pad hemoglobina u trudnoći može biti djelimično razblažen, ali nizak feritin nije objašnjen samo razblaženjem. Feritin ispod 30 ng/mL ukazuje na smanjenje zaliha željeza; nizak hemoglobin sa feritinom od 30 ng/mL ili više zahtijeva širu analizu anemije.

Slika 3: Veličina ćelija i feritin zajedno odvajaju razblaženu anemiju od iscrpljenosti željezom.

Fiziološka hemodilucija dostiže svoj vrhunac oko 28. do 32. sedmice, kada volumen plazme raste brže od mase crvenih krvnih zrnaca. To može smanjiti hemoglobin za oko 5 do 10 g/L bez patološkog procesa. Feritin se ponaša drugačije: odražava dostupno skladišteno željezo, a uporan rezultat od 12 ng/mL znači da je željezna "ostava" zaista blizu prazne.

Najvažniji obrazac je feritin ispod 30 ng/mL, MCV se smanjuje ispod 80 fL, povećava se RDW, a zasićenost transferina ispod 20%. Nasuprot tome, hemoglobin od 106 g/L sa feritinom 55 ng/mL, MCV 88 fL i normalnim CRP može biti uglavnom posljedica razrjeđenja. Naš članak o niskom hematokritu objašnjava zašto promjene koncentracije mogu zbuniti kompletnu krvnu sliku.

Povremeno viđam pacijente kojima je rečeno da je umor “samo trudnoća” kada im je feritin opao sa 48 na 14 ng/mL tokom 12 sedmica. Samo umor je nespecifičan, iskreno, ali taj silazni trend je uvjerljiviji od bilo kojeg pojedinačnog rezultata. Kantesti AI podržava serijski pregled umjesto da svaki rezultat tretira kao samostalan događaj.

Pročitajte feritin s hemoglobinom, MCV i RDW

Feritin identificira zalihe željeza, dok hemoglobin pokazuje da li je kapacitet nošenja kisika već opao. Trudnica može imati feritin od 9 ng/mL sa hemoglobinom od 116 g/L; to je nedostatak željeza bez anemije, a ne normalan rezultat koji treba zanemariti.

Slika 4: Feritin i markeri kompletne krvne slike odgovaraju na različite dijelove pitanja o željezu.

SZO definiše anemiju u trudnoći kao hemoglobin ispod 110 g/L u prvom i trećem trimestru, a ispod 105 g/L u drugom trimestru. Ovi niži kriterijumi za drugi trimestar priznaju proširenje plazme, a ne nižu potrebu za ishranom. Kompletna krvna slika ostaje esencijalna jer sam hemoglobin ne može pokazati da li se zalihe željeza troše.

MCV ispod 80 fL podržava proizvodnju crvenih krvnih ćelija ograničenu željezom, iako može ostati normalan u ranoj fazi deficita i može biti povišen nedostatkom B12 ili folata. RDW se često povećava prije nego što MCV padne jer novonastale ćelije postaju manje od starijih ćelija. Promjena RDW nakon tretmana se može očekivati; pročitajte naš vodič za RDW nakon terapije željezom prije nego što pretpostavite pogoršanje rezultata.

Kantesti je AI platforma za tumačenje krvne slike dizajniran da čita feritin zajedno sa kompletnom krvlju umesto da proglašava rezultat normalnim jer se usko uklapa u generički referentni limit. Po mom iskustvu, kombinacija feritina ispod 30 ng/mL i opadajući trend hemoglobina je više za akciju nego bilo koji marker sam.

Kada CRP ili bolest čine da feritin izgleda bolje nego što jest

Feritin se povećava tokom upale, tako da normalan ili visok feritin ne može pouzdano isključiti nedostatak željeza kada je CRP povišen. U trudnoći, feritin od 45 ng/mL uz CRP 20 mg/L može predstavljati nedostatak željeza maskiran upalom, a ne obilne zalihe željeza.

Slika 5: Upala može povisiti feritin i sakriti ograničenu dostupnost željeza za proizvodnju crvenih krvnih ćelija.

Feritin je reaktant akutne faze. Virusna bolest, autoimuna bolest, gojaznost, povreda jetre, pa čak i nedavna vakcinacija mogu ga podići nezavisno od uskladištenog željeza. CRP iznad gornje laboratorijske granice – često 5 mg/L—treba da navede kliničara na veću opreznost u vezi sa pozivanjem rezultata feritina kao umirujućeg.

In that setting, transferrin saturation below 20%, low serum iron, or raised soluble transferrin receptor can provide useful corroboration. Serum iron itself fluctuates with time of day and recent food intake, so I never diagnose pregnancy iron deficiency from serum iron alone. Our explanation of ferritin i CRP covers this common mismatch.

A febrile patient at 30 weeks with ferritin 70 ng/mL, CRP 64 mg/L, and haemoglobin 96 g/L needs clinical evaluation for the illness as well as an iron plan. Do not self-prescribe high-dose iron solely from one inflamed panel; the cause of anaemia may be mixed.

Simptomi niske razine feritina u trudnoći: korisni tragovi, ne dokaz

Low ferritin in pregnancy may cause no symptoms at all, especially above 15 ng/mL, but reduced exercise tolerance, unusual fatigue, palpitations, headaches, restless legs, and ice craving can occur. Symptoms cannot distinguish iron deficiency from sleep loss, thyroid disease, infection, or anxiety without laboratory context.

Slika 6: A symptom-focused consultation connects fatigue with objective iron and blood-count findings.

Craving ice, called pagophagia, is one of the more specific clues I hear in clinic; it can improve surprisingly quickly once iron deficiency is corrected. Breathlessness climbing stairs can occur in normal pregnancy, too, so the shift from “usual effort” to a new limitation matters more than the symptom’s mere presence. A haemoglobin below 100 g/L makes a laboratory explanation more likely.

Restless legs in the evening is associated with low iron stores, and some sleep-medicine guidance uses ferritin below 75 ng/mL when considering iron in non-pregnant adults. That does not mean every pregnant person needs to reach 75 ng/mL. It does explain why a ferritin of 24 ng/mL may matter even before anaemia appears.

New marked breathlessness, a resting heart rate persistently above 120 beats/minute, fainting, chest pain, or inability to manage ordinary activity needs same-day maternity or urgent-care advice. For more targeted triage, see our vodič za testiranje krvi kod kratkoće daha.

Što kliničari obično rade kada je feritin ispod 30

Ferritin ispod 30 ng/mL in pregnancy commonly leads to dietary advice plus oral iron, with the dose and urgency tailored to haemoglobin, symptoms, gestation, and tolerance. Oral elemental iron doses of 40 to 100 mg once daily or on alternate days are widely used, but the exact product should be agreed with your maternity team.

Slika 7: Dietary iron and prescribed supplements can rebuild depleted stores during pregnancy.

Alternate-day dosing has a plausible physiological advantage: hepcidin rises after an iron dose and can temporarily reduce absorption from the next dose. Clinical practice varies, and evidence in pregnancy is still evolving, so I do not present alternate-day dosing as universally superior. Nausea, constipation, and reflux often determine what a patient can actually continue.

Take oral iron away from tea, coffee, calcium supplements, and antacids where possible; these can reduce absorption. Vitamin C-rich food may modestly improve non-haem iron uptake, but expensive vitamin C products are rarely necessary. Our guide to iron-rich foods offers practical meal combinations.

Intravenous iron is generally considered after the first trimester when oral treatment fails, is not tolerated, malabsorption is likely, or significant anaemia is discovered late. A 34-week patient with haemoglobin 84 g/L should not simply wait months for dietary changes to work. The obstetric team needs to weigh IV iron, delivery timing, and blood-loss risk.

Kada ponoviti feritin i kompletnu krvnu sliku

After starting iron, a full blood count is often repeated in 2 do 4 sedmice to confirm response, while ferritin is usually rechecked later because it may rise slowly and varies with inflammation. A haemoglobin increase of roughly 10 g/L within 2 to 4 weeks supports effective treatment when adherence and absorption are adequate.

Normal range for ferritin followed through sequential laboratory samples and a calendar-free clinical workflow
Slika 8: Follow-up testing verifies that iron treatment improves red-cell production, not just symptoms.

A reticulocyte response may begin within 7 do 10 dana, although it is not routinely measured in every maternity clinic. If haemoglobin has not moved after 2 to 4 weeks, clinicians check the dose, missed doses, vomiting, antacid use, ongoing blood loss, B12 and folate status, and whether the original diagnosis was correct. Do not double the dose yourself before that review.

Ferritin can be falsely elevated for several weeks after intravenous iron, so an immediate post-infusion level does not show durable body stores. For oral treatment, many teams continue therapy for at least 3 months after haemoglobin normalises and into the postpartum period, but local protocols differ. The vodič za vremensku liniju krvnih pretraga explains why intervals matter.

Kantesti AI can compare sequential ferritin, MCV, haemoglobin, and RDW results to identify a meaningful response rather than highlighting tiny analytical changes. For interpretation standards and clinical review processes, our readers can consult medicinska validacija.

Kada nizak nivo feritina zahtijeva hitnu procjenu majke

Low ferritin itself is rarely an emergency, but anaemia symptoms or signs of blood loss can be. Seek urgent maternity assessment for fainting, chest pain, breathlessness at rest, a sustained pulse above 120 beats/minute, heavy vaginal fluid loss, or reduced fetal movement—regardless of your last ferritin number.

Normal range for ferritin discussed during an urgent maternity triage consultation in a calm clinic
Slika 9: Urgent symptoms require maternity triage rather than waiting for routine iron follow-up.

Hemoglobin ispod 70 g/L in pregnancy is severe anaemia and requires urgent specialist assessment; the right treatment depends on symptoms, gestational age, cause, and active loss. A result of 85 g/L may also require expedited action late in pregnancy or in someone with cardiopulmonary symptoms. Numbers guide urgency, but the person in front of us matters more.

Black, tarry stools before iron has been started, vomiting blood, persistent abdominal pain, or a history of bowel disease requires medical review rather than the assumption that pregnancy caused iron deficiency. Once oral iron has begun, stools commonly darken; that expected effect should not be confused with gastrointestinal bleeding. This distinction is covered in our blood-test pale-skin guide.

Call emergency services for collapse, severe chest pain, severe breathing difficulty, or heavy bleeding. Contact your maternity unit the same day for reduced movements or a new combination of dizziness and palpitations. It is better to be assessed and reassured than to wait for a scheduled blood draw.

Može li feritin biti previsok tijekom trudnoće?

Ferritin above the laboratory range in pregnancy is not usually caused by excess dietary iron alone. Values above 150 to 200 ng/mL should prompt clinicians to consider inflammation, liver disease, metabolic conditions, iron therapy history, or less commonly iron overload, especially when transferrin saturation exceeds 45%.

Normal range for ferritin contrasted with a high-result iron storage molecular visualization
Slika 10: High ferritin needs context because it can reflect tissue response rather than iron excess.

Ferritin often falls during an uncomplicated pregnancy, so a rising level deserves a contextual look. CRP, ALT, AST, transferrin saturation, and a careful medication history are more informative than ferritin alone. A high ferritin with low transferrin saturation is commonly an inflammatory pattern, not proof that iron should be withheld indefinitely.

Hereditary haemochromatosis is uncommon as a cause of pregnancy ferritin elevation, and pregnancy may lower stores through fetal demand and delivery blood loss. Still, persistent ferritin above 300 ng/mL with transferrin saturation over 45% warrants non-urgent clinician-led evaluation once acute illness has been excluded. Read our overview of iron-overload clues obrazac.

Avoid taking additional iron if a clinician has told you ferritin is high until the full iron panel has been reviewed. Conversely, stopping a prescribed prenatal vitamin over a modest ferritin rise without advice can create a different problem. Context wins here.

Izbori hrane koji pomažu kada je feritin u trudnoći nizak

Food supports iron repletion but rarely corrects late-pregnancy iron-deficiency anaemia quickly by itself. Heme iron from meat, poultry, and fish is generally absorbed more efficiently than non-haem iron from beans, lentils, tofu, grains, and leafy vegetables; both have a place in pregnancy.

Normal range for ferritin supported by lentils leafy greens citrus and iron-rich meal ingredients
Slika 11: Iron-containing foods paired with vitamin-C produce can improve non-haem iron absorption.

A meal containing lentils or beans plus peppers, citrus, tomatoes, or kiwi can increase non-haem iron absorption through vitamin C. Tea and coffee can reduce absorption when taken with the same meal because polyphenols bind iron. Separating them by about 1 do 2 sata is a realistic compromise for most patients.

Prenatal vitamins often contain between 14 and 30 mg of elemental iron, which may prevent deficiency but may not replenish it once ferritin is 8 ng/mL. Check the label because “iron 65 mg” can describe the salt weight rather than elemental iron; ferrous sulfate 325 mg contains about 65 mg elementarnog željeza. That labelling detail causes plenty of confusion.

Kantesti je Alat za analizu krvnih nalaza uz pomoć AI-a that can connect a low ferritin pattern with nutrition planning, while still directing pregnant users to their own clinician for treatment choices. If supplements are involved, our vodič za suplementaciju u trudnoći discusses dose and safety questions worth raising.

Posebne situacije: vegetarijanske dijete, blizanci, prethodna barijatrijska kirurgija i talasemija

Twin pregnancy, a short interval after a previous birth, vegetarian or vegan diets, adolescent pregnancy, heavy pre-pregnancy periods, and bariatric surgery all increase the likelihood of iron depletion. Thalassaemia trait can also produce a low MCV, but it does ne protect someone from developing iron deficiency at the same time.

Normal range for ferritin evaluated with diverse dietary and inherited red-cell pattern clinical materials
Slika 12: Dietary risk and inherited red-cell traits can coexist with iron depletion in pregnancy.

People after sleeve gastrectomy or gastric bypass may absorb oral iron poorly and need earlier specialist input. A ferritin under 30 ng/mL plus persistent anaemia despite a well-taken oral regimen should raise that possibility. Coeliac disease, inflammatory bowel disease, and long-term acid suppression can create similar absorption obstacles.

In thalassaemia trait, MCV may sit below 75 fL even when ferritin is normal, so treating every small-cell pattern with iron is a mistake. Ferritin, transferrin saturation, haemoglobin electrophoresis history, and family ancestry guide the distinction. Our explainer on niska saturacija transferina shows where that measurement helps.

Dr. Thomas Klein has seen the opposite error too: assuming a known thalassaemia trait explains all microcytosis and overlooking a ferritin of 6 ng/mL. Mixed causes are common enough that the full panel is safer than a single-label explanation.

Zašto je praćenje feritina važno nakon porođaja

Ferritin should often be revisited after delivery when antenatal iron deficiency, postpartum blood loss, or persistent fatigue was present. A full blood count at 4 to 8 weeks postpartum is commonly recommended after significant blood loss or antenatal anaemia, although the exact schedule depends on local maternity policy.

Normal range for ferritin reviewed after birth through a parent’s hands holding a laboratory results folder
Slika 13: Postpartum follow-up checks whether pregnancy and delivery have depleted iron reserves.

Ferritin in the first several weeks after delivery can be hard to interpret because delivery produces an inflammatory response that may transiently elevate it. Haemoglobin, symptoms, estimated blood loss, and treatment history often guide early decisions better. Later testing gives a cleaner view of whether stores have been rebuilt.

Continuing prescribed iron after birth can matter even when haemoglobin begins to improve, particularly after blood loss of 500 mL or more following vaginal birth or 1,000 mL or more after caesarean birth—the usual thresholds used to define postpartum haemorrhage. Breastfeeding does not itself drain iron stores dramatically, but recovery needs are real.

Pitanja za vašu primalju, liječnika opće prakse ili ginekologa

The most useful question is not “Is my ferritin normal?” but “Do my ferritin, haemoglobin, MCV, symptoms, and gestational age suggest I need treatment now?” Bring the actual values, units, test date, pregnancy week, supplement name, and any previous results.

Normal range for ferritin reviewed with a clinician using a structured pregnancy laboratory discussion
Slika 14: A structured appointment discussion turns ferritin numbers into an individual treatment plan.

Ask whether your ferritin result was measured during an infection, after IV iron, or with an elevated CRP. Ask whether transferrin saturation, B12, folate, thyroid testing, or haemoglobinopathy screening is relevant in your case. These questions are especially useful when haemoglobin is below 105 g/L in the second trimester or below 110 g/L outside it.

Also ask when to repeat the CBC, whether your iron dose is expressed as elemental iron, and what side effects should prompt a change in formulation. If you have had bariatric surgery, bowel disease, prior severe anaemia, or a planned delivery within 6 sedmica, ask early whether oral iron is enough. A concise kontrolna lista za pregled kod ljekara can make that conversation easier.

Često postavljana pitanja

Kolika je normalna razina feritina tijekom trudnoće?

A ferritin level of 30 ng/mL (µg/L) or higher is commonly considered reassuring for iron stores during pregnancy when there is no active inflammation. Ferritin between 15 and 29 ng/mL suggests low or borderline stores and often leads maternity clinicians to recommend iron support. Ferritin below 15 ng/mL strongly supports iron deficiency in a person without inflammation. The laboratory’s non-pregnant female range should not be used as the only guide because ferritin normally falls as pregnancy progresses.

Je li feritin od 20 nizak u trudnoći?

Ferritin of 20 ng/mL in pregnancy is generally considered low iron stores, even if haemoglobin is still normal. Many obstetric guidelines use 30 ng/mL as the threshold for offering iron supplementation because it identifies depletion before iron-deficiency anaemia develops. The urgency depends on pregnancy week, haemoglobin, MCV, symptoms, and prior trends. A level of 20 ng/mL at 34 weeks usually warrants a more prompt plan than the same level early in the first trimester.

Zašto se feritin smanjuje tokom trudnoće?

Ferritin decreases during pregnancy because the growing fetus and placenta require iron, maternal red-cell mass increases, and stored iron is mobilised. Plasma volume also expands by approximately 40% do 50%, which contributes to lower measured concentrations of several blood markers. However, dilution alone does not explain a ferritin result below 30 ng/mL; that result usually indicates limited iron reserves. Ferritin therefore helps distinguish expected haemodilution from emerging iron deficiency.

Kada treba ponovo testirati feritin nakon početka uzimanja željeza u trudnoći?

A full blood count is commonly repeated 2 do 4 sedmice after starting oral iron in pregnancy, while ferritin may be rechecked later depending on gestation and symptoms. A haemoglobin rise of about 10 g/L within 2 to 4 weeks suggests that treatment is working when the diagnosis and adherence are correct. Ferritin can be temporarily misleading after intravenous iron or during infection because it rises as an acute-phase reactant. Your maternity clinician should set the interval if anaemia is moderate, late in pregnancy, or associated with symptoms.

Može li trudnica imati nizak feritin uz normalan hemoglobin?

Yes. Ferritin can be below 15 or 30 ng/mL while haemoglobin remains above the pregnancy anaemia threshold, which is called iron deficiency without anaemia. This stage means iron storage is depleted but oxygen-carrying capacity has not yet fallen enough to meet anaemia criteria. Treating it may reduce the chance of developing more severe anaemia before delivery, although the exact regimen depends on clinical circumstances. Haemoglobin below 110 g/L in the first or third trimester, or below 105 g/L in the second, meets WHO anaemia criteria.

Koji je nivo feritina opasno nizak u trudnoći?

There is no ferritin number alone that defines an emergency, but ferritin below 15 ng/mL indicates marked iron depletion and needs clinical follow-up. Urgency rises when low ferritin occurs with haemoglobin below 70 g/L, fainting, chest pain, breathlessness at rest, persistent tachycardia, heavy vaginal bleeding, or reduced fetal movement. A person at 36 weeks with ferritin 8 ng/mL and haemoglobin 85 g/L needs faster maternity planning than a well person at 10 weeks with the same ferritin. Symptoms and gestational age matter as much as the ferritin result.
