How to test for PFAS, glyphosate and phthalates at home

Last updated: October 22, 2026

PFAS are usually measured in a blood sample, while glyphosate and phthalates are measured in urine, so an at-home test for all three needs either two samples or two kits. You can buy a single-chemical test (for example a PFAS-only blood test or a plastic-chemicals urine test) or one panel that lists all three. Results show exposure, not illness: CDC notes that a chemical measured in blood or urine does not by itself mean it causes disease.[1][2]

Which sample measures which chemical

Usual sample for each chemical group, with sources.
Chemical groupUsual sampleWhy
PFASBlood or serum[2]PFAS stay in the body for years and nearly everyone in the US has measurable PFAS in blood.[2]
GlyphosateUrine[3]The national NHANES study measured glyphosate in urine and detected it in 81.2% of people aged 6 and over in 2013 to 2014.[3]
PhthalatesUrine (as metabolites)[4]Phthalates are broken down into metabolites that pass out quickly in urine, so CDC measures those metabolites.[4]
BPA (often tested alongside phthalates)Urine[5]NIEHS reports a CDC survey that found BPA in 93% of urine samples from people aged 6 and older.[5]

For PFAS, our PFAS blood test page explains which PFAS are measured and how the blood or serum sample is collected.

Two ways to test

  • Single-chemical kits. A PFAS-only finger-prick blood test, such as empowerDX (16 PFAS), or a plastic-chemicals urine test, such as Million Marker (13 markers including 5 phthalates), covers one group.[6][7]
  • One multi-category panel. Some panels list all three groups in one order. Intrinsic Prism lists glyphosate and phthalates in urine and a PFAS panel in blood or serum; US BioTek MOE-Tox lists glyphosate, 8 phthalates and 3 PFAS in urine.[8][9]

The dated table below lists what each test’s own page names, with a source for every cell.

Tests that list PFAS, glyphosate or phthalates

Seven at-home tests from our dated comparison that list at least one of the three. Phthalates are counted inside environmental chemicals.

Listed alphabetically by provider. This is not a ranking, and it was prepared by Intrinsic Prism, so our own package is included. Counts are the provider’s own published counts or the markers named on its page; categories are grouped by us so the rows can be compared.

Step by step

  1. Decide which groups you need. Check that the named markers, not just a headline count, include the PFAS, glyphosate or phthalates you care about.
  2. Follow the kit’s collection instructions. Urine kits often ask for a first-morning sample; blood kits use a finger prick or a draw.
  3. Expect day-to-day variation for phthalates. Phthalate metabolite levels in urine change from day to day; one sample reflects recent exposure, and repeated samples describe longer periods better.[10]
  4. Read results as exposure. A measured level shows that exposure happened. It does not by itself show a health effect.[1]

The Intrinsic Prism complete package is $1,999 per participant.

Where your drinking water fits

A blood or urine kit tests your body, not your water. To learn about PFAS in your tap water, look at your water system’s results. EPA’s 2024 drinking water rule set enforceable limits (MCLs) of 4.0 parts per trillion for PFOA and for PFOS.[11] If your public water system reported PFAS above the 2024 MCL level, that is a reason to ask your utility about treatment; our PFAS tap water ZIP code lookup shows EPA’s published results by ZIP code.

What results can and cannot tell you

ATSDR says a PFAS blood test tells you how much of certain PFAS are in your blood, but it will not pinpoint a health problem, guide treatment, or predict future health problems.[2] The same caution applies to urine levels of glyphosate and phthalates: CDC’s national exposure data are a reference for comparison, not a safe-or-unsafe line.[1] Talk with a healthcare provider about any result that worries you.

Food residue limits are a separate topic; see glyphosate MRLs by country.

Frequently asked questions

Can I test for PFAS at home?

Yes. Some kits use a finger-prick blood sample that you mail to a laboratory. ATSDR notes that PFAS blood results show levels, not a diagnosis.[2][6]

Is glyphosate tested in blood or urine?

Usually urine. The national NHANES study measured glyphosate in urine samples.[3]

How are phthalates measured?

As their breakdown products (metabolites) in urine, which is how CDC measures them in NHANES.[4]

Does one kit test PFAS, glyphosate and phthalates together?

Some panels list all three, usually with a blood sample for PFAS and urine for the others. Check each test’s named markers in the table above.[8][9]

Will the results tell me if I am sick?

No. A measured level shows exposure. CDC notes that it does not by itself mean the chemical causes disease.[1]
