Malaria is diagnosed by finding the parasite in the blood — by microscopy (the gold standard) or a rapid antigen test (RDT).
| Measure | Range |
|---|---|
| Blood smear (microscopy) | Gold standard; identifies species & load |
| Rapid antigen test (RDT) | Fast; positive/negative |
| If negative but suspicious | Repeat smears over 48–72 hrs |
RDTs are quick and useful, but microscopy remains the gold standard as it identifies the species and how many parasites are present. A negative RDT with ongoing fever should prompt repeat smears.
Any fever after being in a malaria region should be tested promptly — malaria can become severe quickly, so early diagnosis matters.
