The diagnostic tests of malaria include all, except?

Correct option is D

Sol. Hemoglobin test is used to check anemia, not diagnose malaria. Malaria is diagnosed by detecting parasites through microscopy, rapid diagnostic tests (RDTs), and serological tests. The presence of Plasmodium species in blood smears confirms the disease.
Explanation of each option:
· (a) Rapid diagnostic test – Detects specific malaria antigens in blood using test kits; gives fast results.
· (b) Serological test – Detects antibodies against Plasmodium; useful in epidemiological studies.
· (c) Microscope – Correct method for visual confirmation by identifying the parasite in blood smears.
· (d) Hemoglobin test – Incorrect. It detects anemia, which may be caused by malaria but cannot confirm its presence.
