Likewise, what tests are done to diagnose malaria?

Testing is performed to help diagnose malaria, to monitorfor relapses, and to determine drug susceptibility of the parasitecausing the infection.

• Thick and thin blood smears.
• Rapid diagnostic tests (antigen testing)
• Molecular tests (Polymerase chain reaction, PCR)
• Antibody tests (serology)
• Susceptibility testing.

Beside above, can CBC detect malaria? Your doctor may order a blood smear test to be done atthe same time as a CBC but it is not part of the regularCBC test. Blood cells with different shapes or sizescan help diagnose many blood diseases, such asleukemia, malaria, or sickle cell disease.
