Find out about the different types of tests that screen for Covid
PCR
Tests for active infection. These are carried out by taking a sample using a swab inserted into the nostrils and/or the throat. Key features:
• Detects infection in the early days. Amplifies the virus’s genetic material even when present in small quantities.
• High sensitivity for detecting the virus.
Antigen test
Tests for active infection. These are carried out by taking a sample using a swab inserted into the nostrils and/or the throat. Key features:
• Detects the infection for a limited time after the onset of symptoms.
• Low complexity and cost.
• The chosen test must meet WHO criteria.
• Results available in about 15-20 minutes.
Antibody screening tests:
These are not considered tests for active infection. They indicate serological status and may be useful for population studies or in very specific clinical situations.
