Its a similar procedure w/ similar using the same techniques to analyze the hair and the urine sample. The Hair test is done w/ radioimmunoassay typically for the A sample and then if positive the B sample will be run through Mass Spec Analysis. One problem or issue would be 1) Henry is African American, Its not fact, but many studies have shown that depending on race, there are greater chances of false positives w/ the Hair test. 2) may not have the necessary hair length (usually keeps it short I think) almost buzzed to assay whats needed.Urine tests are done first w/ an immunoassay and then Mass Spec. for the B sample. Neither way is more accurate than the other. The hair test can date back further than the urine test. You all probably just read way more about Science than you actually wanted to know.--your friend, The ScientistETA: In court if that B sample tested positive he is guilty.THC will show up in the follicles for 6 months, correct? Urine for a month at the most, correct? If he passes a hair test, which I'm assuming is more accurate than the urine test, wouldn't that settle the matter?
