Buying Guide

Match test to the sample and condition

Choose kits designed for the specimen you can collect (nasal swab, surface sample, blood) and the specific target (COVID-19 antigen, influenza, asbestos, mold, blood type)

Check what’s included

Confirm the kit includes collection materials, instruction clarity, and any lab-fee or analysis services if third-party testing is required

Consider multiplex vs single-target

Multiplex kits that detect flu A/B plus COVID-19 save time when symptoms overlap, while single-target tests can be simpler and faster for one suspected pathogen

Verify regulatory and lab standards

Prefer kits that reference recognized analysis methods (PLM, NVLAP) or specify OTC/over-the-counter eligibility for at-home use

Evaluate test count and reusability

Compare number of tests per pack to expected use—multi-test packs reduce per-test cost for repeated screening, single tests suit one-off needs
