What if a historical period of 6 months of drug use is required, can the laboratory test for that?
Yes. However two separate testing kits would have to be purchased and two separate hair samples be submitted for laboratory processing. The length of the hair would have to start out at a minimum of 3 inches in length from the root end. One sample would then be submitted cut at 1.5″ from the root end for the first test kit, and the second sample representing the remaining hair length be submitted for the second test kit. It is extremely important to place the root end, or the end closest to the root end aligned properly in the foil as described in the kit instructions.
