That depends on what you mean by Skipper "seems to realize this and is at least helping now"? Are you referring to his availability as a paid expert witness or something more? Is this change in perspective presented as genuine mea culpa resulting from a sincere epiphany or is was it written as click bait for his medico-legal services. The specificity of any drug or alcohol test being used for forensic purposes needs to be as close to zero as possible to prevent false-positive tests. False positive tests should be non-existent to very rare. This requires extensive,and detailed research looking at multiple variables including metabolic and genetic differences, validity, cross-reactivity, cutoff levels, etc. etc. These issues need to be known well BEFORE the test is actually used for forensic purposes. The only research done on the EtG when it was introduced in 2003 and the PEth when it was introduced in 2013 was the research concerned with detecting and quantifying and the specificity of these tests is being determined post-market by trial and error. These consequences were predictable and avoidable.

I had a positive blood spot peth (25ng) 4 months before my contract ended. This was I've two years ago now. I am shocked to see a post stating there is a pattern of these false positives near the end of a contract. How common is this?
