Answer:
In the given scenario, Rohan, a 13-year-old school student, has been diagnosed with AIDS. He experiences symptoms such as fever, nausea, headache, and lethargy. The doctor has prescribed certain drugs to prolong his life. The question asks for the diagnostic test that cannot be used to diagnose AIDS.
ELISA:
ELISA stands for Enzyme-Linked Immunosorbent Assay. It is a commonly used diagnostic test to detect the presence of antibodies or antigens in a person's blood. In the case of AIDS, ELISA is used to detect the presence of HIV antibodies. Therefore, ELISA can be used to diagnose AIDS.
PCR:
PCR stands for Polymerase Chain Reaction. It is a molecular technique used to amplify a specific segment of DNA. In the case of AIDS, PCR can be used to detect the presence of the HIV virus in a person's blood. Therefore, PCR can be used to diagnose AIDS.
Western Blotting:
Western blotting is a technique used to detect specific proteins in a sample. In the case of AIDS, Western blotting is used to confirm the presence of HIV antibodies after a positive ELISA test. It helps to differentiate between false-positive and true-positive results. Therefore, Western blotting can be used to diagnose AIDS.
VDRL:
VDRL stands for Venereal Disease Research Laboratory. It is a blood test used to detect the presence of antibodies against the bacteria that cause syphilis. Syphilis is a sexually transmitted infection and is not related to AIDS. Therefore, VDRL cannot be used to diagnose AIDS.
In conclusion, among the given options, the diagnostic test that cannot be used to diagnose AIDS is VDRL. ELISA, PCR, and Western blotting are all valid diagnostic tests used in the detection and confirmation of AIDS.
