Our test standards are measured by sensitivity and specificity.
Sensitivity relates to a test’s ability to detect whether someone is infected with the virus (PCR is most sensitive of all tests).
Specificity relates to the test’s ability to establish the difference between the Covid-19 virus and another virus.
PCR: Is considered as the gold standard of all Covid-19 testing, other test types are measured against this standard.
NAAT: (ABBOTT ID NOW) 94.7% sensitivity, 98.6% specificity
Antigen: Sensitivity 96.8%, Specificity 99.3%
Antibody: Sensitivity for IgM 98.8%, IgG 100% and specificity for both is 100%
Supervised Antigen Self-Test: Sensitivity of 97.1% and specificity of 99.5%
A positive result indicates that the test has detected the presence of the Covid-19 virus. A negative result means that the test has not detected evidence of the COVID-19 virus. Testing is a biological process involving significant complexity and variability, and consequently no testing regime for Covid-19 is 100% accurate in all cases. A negative result does not guarantee that the test subject is free of the Covid-19 virus, nor does a positive result guarantee that the test subject has active, infectious Covid-19. All testing is conducted on this basis.
Test results and any comments given by us on the results are for information only. They are not a clinical diagnosis. They are not a replacement for a full and proper medical investigation and/or a doctor’s advice.
All our tests conform to ISO15189.
