Best at-home total toxin burden test for 2027: early buyer’s guide

The short answer

The best at-home total toxin burden test for 2027 is the one whose categories match your exposures: heavy metals, mycotoxins, environmental chemicals, PFAS and, if you want it, detox genetics, from a certified laboratory. Published combined profiles range from 100+ to 225+ markers, but they count different things.[1][2][3]

Intrinsic Prism measures 133+ markers from one at-home kit, covering all five categories above.[4] This guide does not rank providers; it sets out the criteria and each option’s published details.

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

• Heavy metals such as lead and mercury; ATSDR describes a blood test for lead, and urine panels list many elements.[5][6]
• Mycotoxins from mold and food; FDA notes food contamination usually involves aflatoxins in crops and M1 in milk.[7]
• Environmental chemicals such as BPA, phthalates, parabens, pesticides and glyphosate; NIEHS reports detectable BPA in 93% of 2,517 urine samples in a CDC NHANES survey.[8]
• PFAS, tested in blood; ATSDR says nearly all people in the U.S. have PFAS in their blood.[9]
• Detox genetics, a DNA sample rather than an exposure measurement.[4]

Counts are not like-for-like. US BioTek’s 225+ markers include 120+ organic acids,[3] and Mosaic’s 134 analytes combine an organic acids test with toxicant, mycotoxin and metals panels.[2] Compare the categories and the specific markers you care about.

Lab quality. Look for CLIA certification and CAP accreditation. RealTime Labs states it is CLIA certified and CAP accredited,[1] and Intrinsic Prism samples are analyzed by a CLIA-certified, CAP-accredited US laboratory.[10]

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.[11]

Criteria to compare before you buy

Total toxin burden options compared

Of the options above, based on the pages checked, Intrinsic Prism’s is the one that lists PFAS in blood and detox genetics alongside urine panels; the urine profiles list organic acids, which Intrinsic Prism does not.[4][3][1][2]

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.[4][10] 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.[12][13]

If you want organic acids or mitochondrial markers, the urine profiles above include them and Intrinsic Prism does not list them. If you want PFAS in blood and detox genetics alongside metals, mycotoxins and environmental chemicals, Intrinsic Prism combines those in one order. See also what a total toxin burden test measures.

Frequently asked questions

What is a total toxin burden test?

A combined test that measures several exposure categories, such as heavy metals, mycotoxins, environmental chemicals and PFAS, in one order. CDC notes a measured chemical is a measure of exposure, not proof of disease.[11]

Is a higher marker count better?

Not necessarily. Counts can include organic acids or minerals, so compare the categories and specific markers you need.[3][2]

Is a toxin burden test HSA/FSA eligible?

It depends on the test and your plan. RealTime Labs says its panels may be eligible,[1] and Intrinsic Prism is HSA/FSA eligible with an itemized invoice; confirm with your plan administrator.[12][13]

Is there 2027 data in this guide?

No. It is an early guide built on provider pages re-checked on November 3, 2026; no 2027 test menus had been published on that date.
