(I think the kitchen rebuilt in the 90s, and there's not a lot of paint layers, but i really don't know.) 16$ seemed like a reasonable price for some extra piece of mind. I've read the home kits aren't always accurate, and the only downside would be what to do with a potential false positive, or difficult to interpret color change. The test is easy to use, dip the Q-tip like swab in vinegar, and rub it on the surface for 30 seconds. Then compare to the color chart. (It fades from yellow to a dark pink red) I tested several areas, and the swab stayed an unambiguous yellow. So far so good. My negative control was the clean floor. Next - I tested some solder wire with lead, and it turned a definitive pinkish red. I only gave 4 stars for accuracy, because i don't know for sure. Overall, if you are looking for a cheap, quick, and easy confirmation that your project is probably safe, this is a great kit. I'd probably go with a professional for a major renovation if you had serious concerns that there was lead. Review: Accurate Lead Testing Kit, Quick and Reliable Results... - Tested this kit on multiple surfaces, including some I suspected had traces of lead, and it worked as advertised. Results showed within 30 seconds, and I could easily confirm the presence of lead. The instructions were clear, and with 30 swabs included, I had more than enough to test all the areas I was concerned about. This kit is a "must-have" for anyone looking to identify lead hazards quickly and accurately. Note that lead is NOT only on walls and paint.. A lot of products coming from overseas are testing positive for traces of lead, and inside homes, there may be lead on plumbing, paint, ceramic tiles and glazes in some homes or pottery especially with decorative glazes may contain lead... Plastics/Rubber/Silicone/Electronics etc.. Furniture and antique toys, and get this > Bathtubs, it turns out that older porcelain-coated bathtubs can have lead in the glaze and leak lead over time... In addition: Electronics and Cables: Some older electronics and cables (like power cords) contain lead in their coatings. If in doubt, CHECK IT.. This kit will do that... Good luck. ## Features - DON’T BE MIS-LEAD: Generic ORANGE swabs are unreliable. Falsely advertised for use on multiple surfaces, these poorly manufactured tests are misleading and prone to false results. Don’t just take our word for it—check the reviews for yourself! - SCIENTIFICALLY FORMULATED: Scitus Labs' lead testing kits offer an exceptionally reliable method for detecting lead on painted surfaces—by using vinegar to activate, our swabs trigger a targeted chemical reaction that specifically identifies lead, ensuring greater consistency and accuracy compared to generic water-activated lead tests. - MADE IN THE USA: Our lead tests are proudly manufactured in the United States for 100% quality assurance. We take pride in our exceptional product, delivering accurate, fast, and reliable lead testing results for personal and professional use. - TRUSTED QUALITY: Scitus Labs offers the most reliable lead paint testing kits available. Our swabs deliver highly accurate results on painted surfaces, and we stand by every claim we make. It’s important to note: NO lead testing swab can guarantee accuracy on unpainted surfaces like toys, ceramics, pottery, china, stoneware, dish- ware, tiles, or bathtubs. Don’t be misled by manufacturers who claim otherwise! - RAPID RESULTS: Scitus Labs lead testing swabs produce highly accurate results in just 30 seconds. The chemical reaction happens quickly when testing for lead on surfaces which have signifigant exposed lead, this is the most dangerous type. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 4,699 Reviews | ## Images ![Scitus, Know Understand 30 Lead Tests for All Painted Surfaces, Get Results in 30 Seconds, Test Painted Surfaces Around The House - Image 1](https://m.media-amazon.com/images/I/71uEUi7j3HL.jpg) ![Scitus, Know Understand 30 Lead Tests for All Painted Surfaces, Get Results in 30 Seconds, Test Painted Surfaces Around The House - Image 2](https://m.media-amazon.com/images/I/71SvGBUVWuL.jpg) ![Scitus, Know Understand 30 Lead Tests for All Painted Surfaces, Get Results in 30 Seconds, Test Painted Surfaces Around The House - Image 3](https://m.media-amazon.com/images/I/71GPjlsEkaL.jpg) ![Scitus, Know Understand 30 Lead Tests for All Painted Surfaces, Get Results in 30 Seconds, Test Painted Surfaces Around The House - Image 4](https://m.media-amazon.com/images/I/81iwvjjESEL.jpg) ![Scitus, Know Understand 30 Lead Tests for All Painted Surfaces, Get Results in 30 Seconds, Test Painted Surfaces Around The House - Image 5](https://m.media-amazon.com/images/I/91pSc+2gCCL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this work to test on dishes? I have antique dishes that I'm concerned might have a lead glaze.** A: I’m sorry our test isn’t intended for testing dishes, it most likely will detect the lead but there is a false negative rate higher than is acceptable to us. So we cannot recommend it, if you would like to try please pm us after buying and we will talk further. **Q: The swabs are consistently negative (orange brown) , but the painting looks kind of pink. Is this (+) for lead?** A: I had the same issue with these swabs. In the area where the swab was used the area turned very light pink, kind of, while the swab stayed light orange/light tan. Until I hit a two areas on the outside of the house where the swab turned purple. Then I knew the swabs were working correctly. **Q: Can this be used on steel pet dishes?** A: I would think so, but you might have to scrape away any surface layers of metal to get to what is underneath if that is what you are trying to test. If you think the dish is lead and there is nothing else on the surface it might work directly on the surface layer of metal. **Q: What is the accuracy rate for negative results? (In my case I would like to test old interior paint)** A: I did not get any results when using this. I do not recommend it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quick, cheap, easy, my positive and negative controls worked. *by J***S on November 7, 2019* Refinishing kitchen cabinets on my own and I was reasonable confident that there's no lead, but my house is old, and I can't be sure.

The process was easy enough and the instructions are clear. The process is a bit more involved with the vinegar than your standard ones, but if it's truly more accurate then it is worthwhile. ## Frequently Bought Together - Accurate Lead Testing Kit, 30 Surface Swabs, Get Results in 30 Seconds, Test Painted Surfaces Around The House for Lead - Water Testing Kits for Drinking Water: 125 Strips 16 in 1 Well and Drinking Water Test Kit, TESPERT Water Test Strips with Hardness, pH, Lead, Iron, Copper, Chlorine, and More --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/106170841-scitus-know-understand-30-lead-tests-for-all-painted-surfaces](https://www.desertcart.co.th/products/106170841-scitus-know-understand-30-lead-tests-for-all-painted-surfaces) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
