As many have noted, Labcorp has recently changed their lower limit of detection from .014 back to .006. While my last few results were <.014, I decided to get a test for my 10-year post-op anniversary and my reading came back as .008. No "<" since .008 is obviously higher than .006. Many studies I've seen cited here and elsewhere seem to define "undetectable as < or = .03. In the past, Tall Allen has written that anything under .03 is fine. Is that still the current thinking?
Thanks and wishing all here the best!
