Review: Quick, cheap, easy, my positive and negative controls worked. - 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. (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: Works nicely & easy too use!! - Tried the other brand that you only get a couple in the package for nearly $20, and have to break glass tubes inside the cardboard etc etc. Half came dried up, and hurt my hands breaking glass tubes, and the only way to get your money worth was squeezing liquid into a bowl and using your own qtips to get multi uses out of one tube. This other product..... Love them!!!! Come with the dried solution on them bundled in like a pair twisted...... Similar to Snap Pops on the fourth of July. Do in tiny bit of vinegar and rub on your item. I used multiple sides on different items to get even more out of them when no lead was present on the first item. Great price, less mess, less hassle and easy to use!!! It is not easy sometimes to determine the colors difference, but can tell you from experience, when it finds lead, it gets dark. Definitely know when you find lead. Will buy these from now on!!! Highly recommend!!

### ⭐⭐⭐⭐ Seems to work, but no internal standard and no documented positive or negative predictive values.
*by S***E on September 14, 2024*

Bought a house from the early 70s, unknown if any lead-based paint. Have a baby - got these to check out the paint before removing wallpaper and repainting what will be her nursery. All these test swabs were negative (turned yellow when dipped in white vinegar and stayed yellow after rubbing in chopped areas of paint) BUT my mom-paranoia had me concerned that the tests could be falsely negative since there is no internal test to verify the swabs were working (understandable that you might not want to put a lead something in a kit, I get it). So I bought a lead fishing sinker and the tests swabs turned very obviously purple! I was happy with this but my mom-paranoia would not let me rest before I sanded the dickens out of the nursery before repainting, since I still could not find data on the false negative rate on the product packaging, or much info about the validity of the company on their website. Of note this test is not EPA certified as of my check on their website. So my mom-paranoia made me then get the EPA certified D-Lead tests. The D-Lead test was also negative. So in summary, these tests agreed with the EPA certified tests, but unclear how sensitive they are relative to the certified tests.
