## Description

Scitus, Know Understand 30 Lead Tests for All Painted Surfaces, Get Results in 30 Seconds, Test Painted Surfaces Around The House: desertcart.com: Industrial & Scientific

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!!

## 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.

## 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.

### ⭐⭐⭐⭐ 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.
