VoriconazoleDrug MonitoringLab Interpretation A correctly timed voriconazole trough helps assess whether antifungal exposure is adequate without becoming excessive. Many treatment protocols use approximately 1–5.5 mg/L, but the infection, prevention plan and side effects determine your personal target.

Urine CystineKidney StonesLab Interpretation High urine cystine suggests cystinuria when supported by quantitative testing, characteristic hexagonal crystals or a cystine-containing stone. A positive screening test alone is not confirmation, and collection errors can change the result.

LacosamideMedication MonitoringLab Interpretation A lacosamide level measures Vimpat exposure, not whether treatment will definitely work. Some laboratories use 1–10 µg/mL, but interpretation depends on the laboratory's interval, dose timing, kidney function, seizure control and side effects.

MethotrexateDrug MonitoringLab Interpretation After high-dose cancer treatment, a falling drug concentration is only part of the story. Infusion timing, kidney changes, and the rescue protocol explain why another laboratory check may mean another hospital night.

GalactomannanLab InterpretationAspergillus A positive galactomannan result supports possible invasive aspergillosis but does not confirm it. The specimen, immune status, scan findings and medications determine whether the next step is urgent assessment, additional testing or investigation of a misleading result.

CotinineLab InterpretationNicotine Exposure Nicotine has a roughly 2-hour half-life, but cotinine can remain detectable for several days. A positive result shows nicotine exposure—not necessarily tobacco smoking—and its meaning depends on the specimen, cutoff and exposure history.

SalicylateLab InterpretationMedication Safety A salicylate level cannot establish safety by itself: clinicians interpret it with symptoms, blood pH, kidney function and repeat measurements. An early low result can miss delayed aspirin absorption, while chronic toxicity can be serious at lower concentrations. Suspected poisoning needs immediate assessment—not a wait for laboratory results. Medically reviewed by Thomas […]
SeHCATBile Acid DiarrheaTest Interpretation Low seven-day SeHCAT retention supports bile acid diarrhea: commonly used bands are below 5% severe, 5–under 10% moderate, and 10–under 15% mild. These percentages guide treatment discussions, but do not measure symptom severity or identify the underlying cause on their own.

VEGFNeuropathyLab Interpretation A VEGF blood test can help investigate unexplained neuropathy and possible POEMS syndrome. An elevated result supports—not confirms—the diagnosis, and serum versus plasma sampling can substantially change the number.

Dientamoeba fragilisStool PCRLab Interpretation A positive stool PCR does not automatically mean you need medication.
