Molecular Tests: Sometimes called NAATs (Nucleic Acid Amplification Tests), Diagnostic Tests, Viral Tests, RT-PCR Tests or RT-LAMP Tests. Molecular tests are typically highly accurate and do not require follow-up testing after receiving results.

Antigen Tests: Positive results are considered highly accurate, but negative results may need to be followed up with an additional test.

Screening Tests: Tests that are administered with the intention of detecting infections to prevent spread before people become symptomatic. These are great for testing workers before they enter the workplace, periodic testing at regular intervals (such as weekly), testing new staff, and testing workers with prolonged absences.

Diagnostic Tests: Tests that are used to diagnose a current infection. These tests are best for on demand use for people who are showing symptoms of COVID-19 or were recently exposed to a positive SARS-COV-2 infection.

CLIA: The Clinical Laboratory Improvement Amendments (CLIA) regulate laboratory testing and require clinical laboratories to be certified by the Center for Medicare and Medicaid Services (CMS) before they can accept human samples for diagnostic testing. Laboratories can obtain multiple types of CLIA certificates, based on the kinds of diagnostic tests they conduct
