Oh, that's simple - it's defined as above the 98th percentile.

- jmalicki 5y agoActually, the CDC defines the 5ug/DL as high based on being the 97.5%ile [1] in children... so you're not kidding... But if only 2% of children have lead levels that were originally defined based on the worst 2.5%, that's a 20% reduction, so great news!?

- marcosdumay 5y agoStill, I'm not sure the article uses the CDC definition. Going on with the complaint, the article is meaningless. Did they find a problem? An improvement? Nothing? Nobody can tell by reading it alone.
