Consider the following pairs:

  1. Widal test→ Typhoid
  2. Rapid sputum test→ Swine flu
  3. Blood smear→ Malaria

  Which of the above is/are correct?

Answer: [C] 1 & 3 Only

Rapid sputum tests are used to diagnose tuberculosis (TB) when other tests show that a person probably has TB. Positive IgM and IgG tests for dengue antibodies detected in an initial blood sample mean that it is likely that the person became infected with dengue virus within recent weeks. Doctors use thick and thin blood smears to determine whether one has malaria.
