Best PFAS test at home for 2027: early buyer’s guide

The short answer

The best PFAS test at home for 2027 is a blood test that lists the PFAS you care about, from a certified laboratory, read with realistic expectations. ATSDR says nearly all people in the U.S. have PFAS in their blood, and a PFAS blood test will not identify a current or future health problem or provide treatment information.[1]

Intrinsic Prism includes 21 PFAS measured in blood or serum within its 133+ marker test.[2][3] This guide does not rank providers.

About this 2027 guide

This is an early guide for people planning testing in 2027. It uses each provider’s published details as re-checked on November 3, 2026. No provider had published a 2027 test menu on that date, so nothing here is 2027 data; we will update the page when providers change their panels.

What to measure, and lab quality

• Which PFAS. EPA notes there are thousands of PFAS chemicals,[4] so every test measures a selected list. Check for the compounds you care about, such as PFOA, PFOS, PFHxS, PFNA and GenX.[2][5]
• Sample. empowerDX uses a self-collected finger-prick sample of capillary whole blood;[5] Intrinsic Prism uses blood or serum;[3] US BioTek lists 3 PFAS in a urine profile.[6]
• What a result tells you. ATSDR says results show how much of certain PFAS are in your blood, but not clear information about health effects, a specific health problem, treatment, or future health.[1]

Lab quality. Look for CLIA certification and CAP accreditation. Intrinsic Prism samples are analyzed by a CLIA-certified, CAP-accredited US laboratory.[7]

ATSDR suggests talking with your healthcare provider about the limitations, risks and benefits of PFAS testing.[1] CDC’s National Exposure Report is a useful reference point: it is built from blood, serum and urine samples from NHANES subsamples of typically about 2,500 participants per survey period, and CDC notes that finding a chemical in blood or urine is a measure of exposure; it does not by itself mean that the chemical causes disease.[8]

Where Intrinsic Prism fits

Intrinsic Prism’s own package measures 133+ markers from one at-home kit: 29 mycotoxins, 20 heavy metals, 38 environmental chemicals, 21 PFAS and 25 detox-related genetic variants, using urine, blood or serum, and DNA samples analyzed by a CLIA-certified, CAP-accredited US laboratory.[2][7] It costs $1,999 per participant, one-time, and is HSA/FSA eligible; claim with the itemized invoice and confirm eligibility with your plan administrator.[9][10]

If PFAS is your only question, a PFAS-only blood test covers it; Intrinsic Prism suits people who also want heavy metals, mycotoxins, environmental chemicals and detox genetics in the same order. For background, see the PFAS test at home guide.

Frequently asked questions

Is a PFAS test worth it if nearly everyone has PFAS?

It can show your own levels of the PFAS measured. ATSDR notes nearly all people in the U.S. have PFAS in their blood and that results will not pinpoint a health problem or guide treatment.[1]

Blood or urine for PFAS?

ATSDR describes PFAS testing in blood, and the PFAS-focused tests above use blood.[1][5][3] Some broad urine profiles list a few PFAS.[6]

How many PFAS should a test include?

There are thousands of PFAS,[4] so no test covers them all. Published tests list 3, 16 or 21 PFAS; check the compounds named.[6][5][2]

Should I talk to a clinician about PFAS testing?

ATSDR recommends discussing the limitations, risks and benefits of PFAS testing with your healthcare provider.[1]
