The process of studying the symptoms in a person as a result of a disease is called diagnosis. The diagnosis can either be done through a physical examination or by reading briefly through the medical history of the patient. In some cases, tests are carried out to discover the underlying cause of a disease.
Diagnostic methods like serum and urine analysis are conventional methods of disease diagnosis. They were used earlier as the only options available to detect the pathogen but with advancement in technology, techniques like recombinant DNA technology, PCR and ELISA have been developed which not only serves the purpose but helps in early detection of the disease with high accuracy.
