The manufacturer’s website says these test kits correctly identify positive specimens in 94% of tests, and negative specimens in 98% of tests.
The test kits are for doing a so-called lateral flow test for COVID-19 antigens (proteins from the virus).
Doing the test seems pretty straight forward.
The test strip looks the same as the strip in a pregnancy test kit.
C stands for ‘Control’ and T for ‘Test’.
If both lines are colored (the T line may be very faint), the test is positive.
If only the C line is colored, the test is negative.
(If no line is colored, you did something wrong and the test is invalid.)
Here’s a table that I compiled of the types of COVID tests.
|Polymerase Chain Reaction (PCR) ('Molecular')||Antigen||Antibody|
|Detects genetic material from the virus.||Detects proteins from the virus.||Detects immune system antibodies (a spike protein test or a nucleocapsid test).|
|The gold standard to test for an active COVID-19 infection.||Not as sensitive as PCR tests.||Not suitable to diagnose an active COVID-19 infection.|
|Nasal swab sample processed by a lab.||Nasal swab sample processed by lab or with home test kit.||Blood sample processed by lab.|
