Within 5 months of submitting our FDA EUA we processed over half a million COVID-19 samples, supplied 40% of all testing for the Commonwealth of Kentucky, and are only continuing to commit more resources for helping increase the availability of testing on a national level.


The graph shown below should be used as a guide to help you best indicate what testing is best needed at certain times in the infection cycle of a virus.


0-14 Days

2-14 Days

1-8 Weeks

Weeks to Months


Early Infection Phase

PCR Testing Recommended

When the virus enters your body, it starts multiplying, and you may or may not have symptoms.

Mid-Infection Phase

PCR + Antigen Testing Recommended

As the virus multiplies, the body begins to react to the viral antigens, possibly resulting in symptoms.

Later to End Infection Phase

IgM Antibody Test Recommended

As your body starts to fight off infection, your immune system produces IgM antibodies.

Post Infection Phase

IgG Antibody Testing Recommended

As your body continues to fight off infection, it produces fewer IgM antibodies and more long-lasting IgG antibodies.
