PFAS are odourless, tasteless and invisible, so guessing is not an option and strip tests cannot see them at all. This is a mail-in kit analysed by a certified lab, which is the only category of test that returns real per-compound numbers you can hold a filter to afterwards.

A focused panel covering PFOA, PFOS and two dozen other compounds. If you already know your water is otherwise fine and PFAS is the single open question, paying only for the PFAS panel is the cheaper way to answer it.

PFAS rarely arrives alone. Water that picked up forever chemicals often carries lead, heavy metals or disinfection byproducts from the same source, and finding all of it in one round is cheaper than three separate mail-ins.

The widest panel here, covering bacteria and lead alongside the chemistry. Worth it when you are buying a house, inheriting a well, or building a baseline you plan to re-test against for years.

Private wells get no utility testing and no notification letter, so nobody is checking your water except you. This kit runs through state-certified labs and covers the contaminants a well realistically picks up.

This answers a different question than a water test. Water tells you what is coming in now; blood serum tells you what has already accumulated, which is the number a doctor can actually act on and re-check after you change your water.
