Doctors prescribe blood test for patients to confirm malaria. Blood test is done to :

  • A.check for haemoglobin in blood
  • B.check iron in blood
  • C.check for eggs of female anopheles mosquitoes in blood
  • D.check for microbes in blood

Answer: D

The blood test is done to check for microbes in blood.

Malaria is caused by Plasmodium, a single-celled parasite (a microbe) passed on by the bite of an infected female Anopheles mosquito. The parasites multiply inside red blood cells, so a blood smear or rapid test detects them and confirms the disease.

Haemoglobin and iron tests check for anaemia, which malaria can cause but cannot confirm. Mosquito eggs are never found in blood; mosquitoes lay their eggs in water.
