THCA is only present in blood for 24 hours, so quitting from now till Thursday will be sufficient. I don't think they will cross reference anyway, but it's better to be safe than sorry. The urine test will probably be the drug test and I wouldn't rely on the Ultra Klean detox drinks. They are an unreliable source of dilution and could cause you a failed test result. I would look into substituting with a friends clean sample or Quick Fix synthetic urine.
Deige Reviewed by Deige on . Life insurance bloodurine test question- Do they cross reference them?? I'm getting a life insurance "home interview" type exam Thursday morning, which requires both blood and urine samples. I've been an Ironworker for 25 years and battled with job urine tests, and seen a lot of guys bust out when they weren't even dirty. I've been job steward and had to fight for these guys (sometimes myself). Anyway, I'm now on disability retirement at 52 years old, and have to go through it one more time. What I would like to know is this... do they cross reference the blood Rating: 5
