Match the LIST-I with LIST-II
| LIST-I | LIST-II |
|---|---|
| Diseases | Confirmatory tests |
| A. Typhoid | I. Biopsy |
| B. Cancer | II. Amniocentesis |
| C. AIDS | III. Widal test |
| D. Genetic Disease | IV. ELISA |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A-III, B-I, C-IV, D-II
(A) Typhoid — this matches (III) Widal test. The Widal test detects the antibodies the body makes against Salmonella typhi, so it confirms typhoid fever.
(B) Cancer — this matches (I) Biopsy. In a biopsy, a piece of the suspected tissue is cut into thin sections. These are stained and examined under a microscope for cancer cells.
(C) AIDS — this matches (IV) ELISA. ELISA (enzyme linked immuno-sorbent assay) is the test widely used to detect HIV infection.
(D) Genetic Disease — this matches (II) Amniocentesis. A sample of the amniotic fluid around the foetus is taken and its cells are tested. This shows genetic disorders of the unborn child.
