Lead Test Confusion : HomeImprovement

Hey there!

Quick question. Have tons of peeling paint in my garage. Mostly bottom quarter of wall. Grabbed 3M lead testing swab. Performed a few tests and am a bit perplexed.

Sample 1: no change color Sample 2: very slight after 5 minutes Sample 3: a tint purple after 5 minutes

Given the false positive rate of 95% is it recommended I mail it in for testing?

I’m the last when I have done these it is literally pink and red on swab and on wall.


Thanks in advance!
