1. Real Time – PCR
rRT-PCR is the golden standard method of viral diagnostic tests for SARS-CoV-2, the virus that causes Covid-19. This method detects genetic material (nucleic acids) and specifically identifies the RNA (ribonucleic acid) sequences that comprise the genetic material of the virus. Our PCR uses as a sample nasopharyngeal or nasal swab specimen and has as target dual viral genes. The analytical sensitivity of method is (11.5 copies/rxn).
2. Antigen or Rapid Test
Rapid test Is an immunochromatographic assay that detects the presence of a specific viral antigen, which implies current SARS-Cov-2 infection. The test uses as a sample nasopharyngeal or nasal swab specimen and has sensitivity 96,18%, specificity 99,7% and total agreement about 97,7%. The turnaround time ranges from 15 minutes to 4 hours.
3. Antibody test
The laboratory test of each antibody allows us to investigate the immune response of the subject who either became ill with the virus (with or without symptoms) or was vaccinated against the virus. Laboratory testing of antibodies is recommended for at least 14 days either after the onset of symptoms or after confirmation of infection (positive molecular test RT-PCR). The antibody test is performed for epidemiological purposes and not for diagnostic purposes. For the diagnosis of the disease in its acute phase, this method is not suitable.
