A finger-prick test that could outpace measles outbreaks
NCT ID NCT05860920
First seen Sep 02, 2026 · Last updated Sep 03, 2026 · Updated 1 time
Summary
Researchers in Senegal are testing a new rapid diagnostic test for measles that works with a drop of blood from a finger or a swab of oral fluid. The test is designed for use by health workers without lab training, aiming to confirm cases faster during outbreaks. The study will compare the rapid test's results against standard lab methods to measure its accuracy and practicality in real-world settings.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Measles rapid diagnostic test
- What this could lead to
- If the rapid test proves accurate, health workers in remote areas could confirm measles cases on the spot, speeding up outbreak response and saving lives.
- What could go wrong
- The test may not match lab accuracy, especially in early or late infections, and field conditions could affect results. This is a single-country study with 254 participants.

Inclusion Criteria: Patients presenting at study sites: * For whom confirmatory diagnostic testing is currently indicated as per the national surveillance protocol * With clinical signs and symptoms consistent with the WHO suspected measles case definition including: History of fever, or observed fever (\>37.5C) at presentation and a (non-vesicular) maculopapular rash; or clinically suspected measles * ≤ 28 days after the onset of a rash * Who if \<18 years of age, have written, informed consent from their legal guardian (and verbally assent if more than 7 years old) * Who if more than 18 years, give written, informed consent Exclusion Criteria: * Withdrawal of consent or assent as described above, at any time. * Unsuccessful venous blood sampling after a maximum of 3 attempts, or a serum sample is no longer available for any reason. * Clinical signs or symptoms requiring immediate referral/transfer of the patient to another site or centre, and/or for whom participation would involve a delay of urgent clinical interventions or investigations (i.e. potential inclusion of patients requiring immediate clinical management should be deferred until the patient is clinically stable). * Clinical signs or symptoms that may be exacerbated by blood draw or upper respiratory sampling (e.g. stridor or severe respiratory distress) Participants who meet the inclusion criteria should be included in the study but without oral fluid sampling if: * They have a sore mouth or gums that would be exacerbated with oral fluid sampling * They are significantly dehydrated and the mouth is very dry * They refuse or are not able to cooperate with oral fluid sampling
