What type of DNA technology is used to diagnose infectious diseases?

Polymerase chain reaction (PCR) is a key DNA technology used to diagnose Infectious Diseases. It amplifies specific DNA sequences from pathogens, allowing for the detection of even minute amounts of genetic material. This method enables rapid and accurate identification of various infectious agents, including bacteria and viruses, facilitating timely treatment and management of diseases. Other techniques, such as next-generation sequencing and CRISPR-based diagnostics, are also increasingly utilized for this purpose.
