I'm not familiar: with taking hair from the underarm. My understanding is that 100-120 strands of hair are needed for the test, cut as closely from the scalp as possible. The strands must be at least 0.5 inch long; this provides a 30 day drug use history. If you give 1.5 inches, a 90 day drug use report will be provided. Hard to imagine you got this amount of hair from underarm! Ask for clarification from testers.
