Which of the following molecular diagnostic techniques is utilized to detect the presence of a pathogen during the early stage of infection?

Polymerase Chain Reaction (PCR)

The correct answer is Option (4)- Polymerase Chain Reaction

Early diagnosis and understanding the pathophysiology of a disease are crucial for effective treatment. However, conventional diagnostic methods like serum and urine analysis often do not facilitate early detection.

To address this limitation, advanced techniques such as Recombinant DNA technology, Polymerase Chain Reaction (PCR), and Enzyme-Linked Immunosorbent Assay (ELISA) play a significant role in achieving early diagnosis and enhancing treatment outcomes.
