Question

Which one of the following techniques does not serve the purpose of early diagnosis of a disease for its early treatment?

• A. Serum and Urine analysis
• B. Polymerase Chain Reaction (PCR) technique
• C. Enzyme Linked Immuno-Sorbent Assay (ELISA) technique
• D. Recombinant DNA Technology

Answer 1

The Correct Option is A

To determine which technique does not serve the purpose of early diagnosis of a disease for its early treatment, let's examine each option:

1. Serum and Urine analysis: This method is primarily used for monitoring existing conditions and evaluating metabolic functions. It is not specifically designed for early diagnosis of diseases.
2. Polymerase Chain Reaction (PCR) technique: PCR is a molecular biology technique used to amplify and detect DNA sequences. It can identify the presence of specific pathogens, assisting in the early diagnosis of various diseases.
3. Enzyme Linked Immuno-Sorbent Assay (ELISA) technique: ELISA is an immunological assay used to detect the presence of antigens or antibodies. It is commonly employed in the early diagnosis of infectious diseases.
4. Recombinant DNA Technology: This technology is used for creating DNA sequences that have beneficial properties. It plays a role in gene cloning, vaccines, and diagnostics, aiding in the early detection of some genetic diseases.

Based on the analysis, Serum and Urine analysis does not specifically serve the purpose of early diagnosis for disease treatment; it is more of a monitoring tool.
