LONDON, 7 October 2026 — Kantesti Ltd launched Plague Check in London on 7 October 2026. Rolling out in its clinic dashboard at no additional charge, the tool helps doctors consider possible plague early and review next steps within the same hour.

Plague decision support addresses a time-sensitive question

Plague is a rare, treatable bacterial infection caused by Yersinia pestis, not a virus. Cases still appear each year in DR Congo, Madagascar, Mongolia and the United States. The source document also describes a suspected, unconfirmed laboratory-linked case in Siberia that authorities are watching.

Antibiotics started early save most patients, while untreated pneumonic plague is almost always fatal. Plague Check is intended to help healthcare professionals consider possible plague sooner and bring relevant information together in minutes; it cannot establish whether a patient has the infection or ensure treatment begins within a particular time.

The World Health Organization plague fact sheet cited in the source document describes spread through flea bites and infected animals, and through droplets in pneumonic plague. It gives an incubation period of about 1 to 7 days. Anyone who develops fever after a possible plague exposure should seek urgent medical care.

“With plague, the danger is not the treatment. It is the hours lost before anyone thinks of it. Plague Check brings the right questions, the patient’s own blood results and the WHO and CDC steps together on one screen, in minutes.”

Clinicians combine blood reports with exposure and symptom answers

A clinician begins by selecting up to five interpreted blood test reports, which the system reads together from oldest to newest. Kantesti AI reads each laboratory value against the reporting laboratory’s own reference ranges. The clinician then answers questions about travel, animals, contacts and laboratory work.

The symptom questions cover fever, painful lymph nodes, bloody cough and signs of sepsis. In minutes, the tool returns a suspicion score, a triage tier ranging from “exposure only” to “act now”, and a WHO case stage. The stages shown in the source document are not a case, suspected, presumptive and confirmed.

Plague Check presents illness severity separately from suspicion, using vital signs and blood results to show signals involving sepsis, clotting, kidneys and the liver. Its next-step information covers confirmatory tests, isolation, public-health notification and WHO and CDC treatment guidance. The clinician can print and share a report; white-label clinics can include their own logo and details on it.

Case-definition rules set a floor beneath the AI assessment

A rule engine based on WHO and CDC case definitions sets a minimum level of concern for each assessment. The AI may raise that level but cannot lower it. Suspicion and severity are shown separately so that signs of serious illness are not presented as confirmation of plague.

Routine blood tests can help show how ill a patient is, but they cannot confirm or exclude plague. The report states that limitation and names tests used for confirmation. An illustrative screen in the source document lists blood cultures, a bubo aspirate, an F1 rapid test and PCR; its score of 78 out of 100 is an example, not a reported patient result or performance measure.

Next-step information follows WHO 2021 plague guidance and CDC MMWR 2021. Treatment decisions and all drug doses remain with the treating doctor. Plague Check provides AI-assisted educational information for healthcare professionals; it does not diagnose disease or replace clinical judgement or laboratory confirmation.

Reports are available in 101 languages at no additional charge

Plague Check is rolling out now within the Kantesti clinic dashboard. It is free for every Kantesti premium report customer and every clinic account, with no credits or add-on. The listed cost for those customers and accounts is £0.

Assessment reports are written in a language selected from 101 options. The interface follows the user’s dashboard language, with 39 interface languages available. The report-language and interface-language counts describe different parts of the tool.

Assessments remain in the clinic’s account and are deleted with the associated patient or blood test. Plague Check is intended for healthcare professionals using clinical information; the source document does not describe a separate patient-facing Plague Check service.

The company sets out the limits of the tool

Julian Emirhan Bulut, Founder and Director of Kantesti Ltd, described the time lost before someone considers plague as the reason for bringing questions, blood results and WHO and CDC steps together on one screen. Clinicians remain responsible for assessing the patient and deciding what care is needed.

Kantesti provides AI-assisted educational information. Plague Check is not a medical device. Its suspicion score and triage tier are information to support a clinician’s assessment, not a diagnosis. A doctor must assess the patient and arrange appropriate laboratory confirmation.

The source document includes an illustrative screen showing fever and a painful groin node after handling an animal, alongside example next steps. It does not document a real case or report clinical validation, diagnostic accuracy or patient outcomes. Kantesti’s wider platform turns laboratory results into AI-assisted explanations for more than 2 million users; that figure is not a Plague Check user count.

Frequently asked questions

Who can access Plague Check, and what does it cost?

Plague Check is rolling out in the Kantesti clinic dashboard. It is available at no additional charge to every Kantesti premium report customer and every clinic account, without credits or an add-on. It is intended for healthcare professionals; the source document does not describe a separate patient-facing Plague Check service.

What information does a clinician enter, and what does the assessment return?

A clinician selects up to five interpreted blood test reports and answers questions about travel, animals, contacts, laboratory work and symptoms. The assessment returns a suspicion score, a triage tier, a WHO case stage and a separate view of illness severity. It also provides information on confirmatory tests, isolation, public-health notification and treatment guidance.

Can Plague Check or a routine blood test confirm plague?

No. Routine blood tests can indicate how ill a patient is but cannot confirm or exclude plague. Plague Check names tests used for confirmation in its report, but its score and case stage are not a diagnosis. Clinical judgement, laboratory confirmation and treatment decisions remain with the treating doctor.

What safeguards and guidance does the tool use?

A rule engine based on WHO and CDC case definitions sets a floor for the assessment: the AI can raise concern but cannot lower it. Next-step information follows WHO 2021 plague guidance and CDC MMWR 2021. Assessments stay in the clinic’s account and are deleted with the associated patient or blood test.
