Why is the conventional method for diagnosis not very relevant?

Because early detection is not possible.

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.
