What is this test?

This test looks for proteins from malaria parasites in a blood sample. It can quickly support a diagnosis when malaria is suspected, but results must be interpreted with symptoms, travel or exposure history, and other laboratory findings.

Why might I need this test?

Your clinician may order it if you have fever, chills, sweats, headache, muscle aches, nausea, or vomiting after travel to or residence in an area where malaria occurs. It may also be used to evaluate suspected malaria infection in people returning from an affected region.

How is the test performed?

A small amount of whole blood is placed on a test cartridge or strip. The result appears within the time specified by the laboratory or test manufacturer, and a control line helps show whether the test was performed correctly.

How do I prepare for the test?

No fasting is usually required. Tell your clinician about recent travel, malaria exposure, prior malaria treatment, medications, and immune-suppressing conditions because these can affect interpretation.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A positive result may indicate malaria infection, but false-positive and false-negative results can occur. A negative result does not completely exclude malaria, particularly early in infection or at low parasite levels, so your clinician may order a blood smear, repeat testing, or molecular testing based on the clinical situation.

Short name

Malaria rapid antigen test

Frequently asked questions

Does a positive malaria rapid antigen test mean I definitely have malaria?
It strongly suggests malaria, but your clinician should confirm the result and determine the parasite species and appropriate treatment. A blood smear or molecular test may be needed.
Can a negative result rule out malaria?
No. Rapid antigen tests can miss infection, especially early after symptoms begin or when the parasite level is low. Your clinician will interpret a negative result alongside your symptoms and exposure history.
Does this test show which type of malaria I have?
The rapid test may not reliably identify the malaria species. Additional laboratory testing is often used to determine the species and guide treatment.
