Forever Chemicals in My Blood: What I Learned Testing for PFAS and Microplastics

I recently took the plunge and tested my blood for microplastics using Bryan Johnson’s Blueprint test. The results came back: 17 particles detected, all under 10 microns in size. My initial reaction? Skepticism about what this actually means.

After digging deep into the science, I’ve concluded that PFAS testing is genuinely actionable while microplastics testing is mostly an expensive data point—at least for now. Here’s what I learned, and how you can get tested yourself for less.

My Blueprint Microplastics Results: The Hard Truth

My Test Results (January 8, 2025)

| Total Particles | 17 |

| Size Distribution | 100% under 10µm (smallest, most concerning size) |

| Concentration | 170 particles/ml |

| Population Percentile | Better than 44%, worse than 26% |

What This Actually Tells Me

Virtually nothing actionable. Here’s why:

1. No clinical thresholds exist. Unlike PFAS, where ≥20 ng/mL triggers follow-up care, there’s no established “safe” or “dangerous” level of microplastics.
2. No polymer identification. The test doesn’t tell me what kind of plastic. Without knowing the type, I can’t identify my exposure source.
3. Self-selected comparison population. I’m being compared to people who paid $199 for a Bryan Johnson longevity test—biohackers, not a representative sample.
4. High day-to-day variability. Blood microplastics fluctuate based on recent meals, environment, and hydration.

The Honest Assessment

I paid $199 for a number without clinical meaning, compared to an irrelevant population, with no actionable source identification. It’s a curiosity purchase, not a health optimization tool.

The Science: What’s Actually Proven to Harm Humans

PFAS (“Forever Chemicals”) — Strong Evidence Base

The National Academies of Sciences established strength-of-evidence classifications in 2022:

Key stat: 98% of Americans have measurable PFAS in their blood.

What You Can Do Right Now

PFAS are in your blood. The question is what you do with that information. Detox protocols exist — sauna, cholestyramine, activated charcoal, dietary shifts. But the deeper question is systemic: why are we still allowing these compounds to be manufactured at all?

The vial of blood sits on the counter at the lab in West LA. Dark. Ordinary. Containing, as it turns out, the residue of every non-stick pan, waterproof jacket, and fast-food wrapper that ever touched this body. The forever chemicals are already inside. The question is what to do with that knowledge.

The phlebotomist's gloves — latex, powder-free — snap against her wrist. The tourniquet tightens. Three tubes fill. One for PFAS. One for microplastics. One for the standard panel that will tell me nothing I don't already know. The interesting data is in the first two.

PFAS testing has crossed the threshold from curiosity to clinical utility. The results come back with reference ranges, source attribution, and actionable protocols — chelation pathways, filtration recommendations, dietary modifications. Microplastic testing, by contrast, remains in its infancy: yes, they're in your blood; no, we don't know what that means yet; no, we can't tell you where they came from. The asymmetry between what we can detect and what we can do about it is the defining feature of environmental medicine in 2026.

Standing in the shower afterward, watching water spiral down a drain that feeds into an ocean already saturated with the same compounds now circulating in my bloodstream — the circularity is not metaphorical. The body is not separate from the environment. It never was. The blood test just made the boundary disappear.

The data is the beginning, not the answer.
