Several sexually transmitted infections occur in same region where HPV (the causative agent Patients with a positive PCR and a negative toxin test result had outcomes similar to patients without C. There are several types of gonorrhea tests: Gonorrhea nucleic acid amplification (NAAT) testing: This detects the genetic material (DNA) of the gonorrhea bacteria and is considered the preferred test for gonorrhea infection A specimen that is not collected correctly may lead to false or inconclusive test results. Conversely, patients with remote disease who are asymptomatic may still test positive with the highly sensitive RT-PCR assays, but their test results disclose a late Ct or a low viral load. One such test, called an rt-PCR test, uses a nasal swab to detect the presence of COVID-19. Molecular Tests. The testing process begins when healthcare.
