If you test your home for lead, you are doing your job as a parent.

You don't get a medal for protecting your kid from something they can't see. You also don't get one for ignoring it.

The standard most parents already meet

You lock the cabinets. You install the car seat correctly. You check the smoke alarm batteries. You read the ingredients on the back of the food label.

That's the standard. Anyone who calls themselves a parent and doesn't do those things is being judged by other parents, and they should be. The cost of doing those things is small, the consequence of not doing them is huge, and the responsibility is unambiguous.

Testing your home for lead is in the same category.

The cost is small. The consequence is real. The responsibility is yours.

Why most parents haven't done it yet

It's not because they don't care. It's because the existing options are bad:

  • $5 swabs from the hardware store, too coarse to catch what actually matters, only test paint, won't find lead in dust or ceramic glaze.
  • $300+ professional XRF inspector, accurate, but you're paying a lot per home and the inspector is gone in an hour.
  • The "5 PPB is dangerous" influencer panic, generates clicks, doesn't give you the dose math you need to make decisions, monetizes alarm.
  • The blood lead test at the pediatrician's, that tells you a child has already been exposed. The point is to find the source upstream and remove it before it becomes a blood number.

There is a different option

A vintage decorated teapot glowing bright green under UV light, perovskite-based field lead test detecting lead in old decorative paint
Same chemistry, applied to a vintage teapot. Bright green = lead in the painted decoration.

Fluoro-Spec is a methylammonium-bromide perovskite reagent. You spray it on a suspected surface, hit it with a UV flashlight, and you see the result in seconds. If there's bioavailable lead, the surface fluoresces green.

It's the same fluorescence-spectroscopy chemistry that the Helmbrecht and Noorduin lab at AMOLF (Netherlands) published in Nature Chemistry in 2018. The same chemistry as the Lumetallix product. The same chemistry as the generic Chinese MABr reagents on Amazon. We just make it cheaper, ship it faster, and it's manufactured by an EPA TSCA-licensed U.S. facility (LVE No. L-25-0206).

What you actually check, in priority order

  1. Painted surfaces in any pre-1978 house, door frames, window sashes, baseboards, friction surfaces.
  2. Decorative paint on dishes, coffee mugs, baby plates, vintage Pyrex, ceramic dinnerware. The decoration band that touches lips is the highest-priority spot.
  3. Brass faucet handles and fixtures, federal "lead-free" still allows up to 0.25% lead.
  4. Garden hose end fittings, virtually all consumer hoses have leaded brass at the connector.
  5. Vintage decorative items, hand-me-down ceramics, vintage glassware, antique brass.
  6. Dust on horizontal surfaces in older homes, window sills, door jambs, areas of friction.

What other parents found

The reactions on first use are pretty consistent: parents go straight to the things they handle every day, the coffee mug, the kid's favorite plate, the brass doorknob the toddler chews, and they find what they find. Sometimes the answer is "nothing here." Sometimes it's "oh, that one." Either way, it's answered, and they move on.

The point isn't to live in fear of lead. It's to find it where it is, remove it, and stop thinking about it.

Test with a kit, not a kid

This is my standing rule and the reason I built this product line. Blood-lead screening is a downstream catch, it tells you a child has already been exposed. The point of being a good parent on this issue is to test the environment first, find the source, remove it, and never have the conversation with the pediatrician about an elevated number.

For dose context, what every concentration number you find actually translates to in micrograms of lead per day in your child's diet, use bloodleadcalculator.com, the free tool I built that maps 700+ food items to FDA Total Diet Study data and models the actual blood-lead-level outcomes.

Why trust me

I'm Eric Ritter. I've been making consumer lead detection products since 2019. Started with sodium-rhodizonate swabs that cost 10× less than the dominant LeadCheck product. Launched Fluoro-Spec in 2024 after partnering with researchers in geochemistry at Columbia and the perovskite-detection group in the Netherlands.

Fluoro-Spec is manufactured under U.S. EPA TSCA Low Volume Exemption No. L-25-0206, the first compliant U.S. consumer methylammonium-bromide test product. The same chemistry as the imported alternatives, but registered, regulated, and made domestically.

If you want the longer story, read my founder letter. The short version: I'm trying to end lead poisoning, I get to do that by getting test kits into the hands of parents at a price they can actually afford, and the math works because my goal is the kit being used, not the kit being expensive.

FAQ

How long does it take to test something?

About 30 seconds per surface. Spray, shine the UV flashlight, look. Glow = bioavailable lead present. No glow = either no lead or lead is locked in non-extractable form.

Will it work on dust?

Yes, Fluoro-Spec is built for surface and dust detection at single-particle resolution (limit of detection ~80 ng per dust particle). It will not by itself satisfy formal EPA post-abatement clearance, but it will absolutely tell you whether dust on a windowsill or door frame contains lead.

What about ceramic glazes and brass?

Yes, both. The methylammonium-bromide chemistry works on substrates where traditional acid-dissolution tests struggle. Glazed ceramic, painted metal, brass fittings, all in scope.

Is it safe for me to use?

Yes. The reagent is a methylammonium-bromide solution in isopropanol. Per the published literature (and Fluoro-Spec's own published safety data), the reagent is corrosive but not acutely toxic at consumer concentrations. Use the included gloves, wash hands after, don't spray it in your face. Standard chemistry-product handling.
