The human papillomavirus is a serious danger. Diagnosis is necessary to determine the strain of infection and the risk of its oncogeneity. Such information allows to make the most suitable and effective treatment plan.
PCR allows to determine the presence of the DNA of gonococci directly and quantitatively express their concentration in the test material. The investigated material can be sputum, lavage fluid, urine, punctata from various organs and cysts, etc.
In contrast to serological methods for diagnosing tuberculosis infection, detecting antibodies to mycobacteria of tuberculosis, PCR makes it possible to directly detect the DNA of mycobacterium tuberculosis and quantitatively express their concentration in the test material.
Recently for the diagnosis of herpetic infection, the detection of DNA of HSV 1 and 2 in the material of vesicles and ulcers of the skin or mucous membranes (including the conjunctiva of the eyes) using the PCR method (very sensitive, specific and rapid diagnostic method) is used to diagnose herpetic infection.
Direct quantitation of HIV RNA by PCR allows more accurate prediction of the rate of disease development in people infected with HIV, more accurately than CD4 + cell count, and therefore more accurately assess their survival. The high content of virus particles usually correlates with a pronounced impairment of the immune status and a low content of CD4 + cells.
