Which one of the following techiques does not serve the purpose of early diagnosis of a disease for its early treatment ?
Recombinant DNA Technology
Serum and Urine analysis
Polymerase Chain Reaction (PCR) technique
Enzyme Linked Immuno-Sorbent Assay (ELISA) technique
Answers (1)
The correct answer is Option 2) Serum and Urine analysis.
Serum and urine analysis are useful diagnostic techniques, but they do not specifically serve the purpose of early diagnosis of a disease for its early treatment. Serum analysis involves testing the blood serum for various markers, such as antibodies or specific substances, to detect the presence of a disease or assess its progression. Urine analysis involves examining urine for abnormalities that may indicate certain diseases or conditions.
On the other hand, the other options mentioned do serve the purpose of early diagnosis for early treatment:
Option 1) Recombinant DNA Technology: This technology involves the manipulation of DNA to produce specific molecules or substances for diagnostic purposes, such as the production of recombinant proteins or DNA probes for detecting disease markers.
Option 3) Polymerase Chain Reaction (PCR) technique: PCR is a powerful molecular biology technique used to amplify specific DNA sequences. It is widely used in disease diagnosis, including the early detection of infections or genetic disorders.
Option 4) Enzyme-Linked Immuno-Sorbent Assay (ELISA) technique: ELISA is a technique used to detect and quantify specific substances, such as antibodies or antigens, in samples. It is commonly used in disease diagnosis, including the early detection of infections or the presence of specific molecules associated with diseases.
Therefore, the correct answer is Option 2) Serum and Urine analysis.
