Benchmark
PCR catches the infection before symptoms and at the “tail” of the disease; result within 24 hours with an official form. The indications today are pragmatic: institutional requirements, differentiation of severe ARVI in vulnerable patients, epidemiological contacts. The smear is standardized, the form is in two languages if necessary.
When is it appointed?
- ARVI symptoms during the season - rapid separation of flows;
- hospitalization and operations - as required;
- contact with a sick person;
- assessment of post-vaccination/post-infectious immunity (antibodies).
Three questions - three tests
Express antigen answers “am I contagious now” in 20 minutes (maximum accuracy in the first days of symptoms); PCR is the most sensitive “is there a virus” standard for hospitalizations; IgG/IgM antibodies evaluate the immune signature of a vaccination or disease. The choice of test is determined by the task - the doctor or administrator will advise you when making an appointment.
