How Accurate Are Coronavirus Antibody Lab Test Kits?
Highly accurate, and we'll break this down as follows:
The sensitivity for this test using a finger-prick sample was verified to be 97.4%.
This means that for every 1000 people who had previously had a COVID-19 infection, 974 would be detected and 26 would return false-negative results.
So the results will be correct for nearly everyone who takes the test.
This test has been verified and shown to have 100% specificity with finger-prick samples. This means in the performance study there were no false positives from people with other respiratory illnesses, and who were not infected with SARS-COV-2.
Although there is a small chance of a false positive result, your positive result almost certainly results from a SARS-CoV-2 infection, not another virus or disease.
Overall, the results will be correct for nearly everyone who takes the test. Note that some people may recover from a COVID-19 infection without producing antibodies.
We ensure the highest clinical quality Coronavirus testing available by using UKAS accredited, CPA approved and ISO certified laboratories. This is the highest level of clinical accreditation in the UK. We achieve the same level of quality as trusted by NHS hospitals, private clinics & general practitioners.
By utilising over 30 years of testing experience we deliver maximum reassurance for all of our health tests.
