18 Panel Hair Drug Screening

We need to collect MORE than the standard 90 to 120 strands of head hair that is also 1 ½ inches to 2 inches in head hair length. *150 mg is required or a bit less than the thickness of two #2 pencils. For hair length less than 1 ½ inches a zero-to-30-day hair test or a zero-to-60-day hair test may be an option (*see 13 panel hair drug test or 17 panel hair drug test panel). Body hair drug testing options include underarm hair, chest hair, leg hair, facial hair, forearm hair, back hair, and sometimes pubic hair.

Detection time:

A typical 18-panel hair drug screening has an estimated detection time of 90 days from possible usage. Extended detection such as 6 months, 9 months, and 1 year may be an option if the specimen donor has long enough head hair. Segmented hair follicle testing may also be done in 30 day increments (*for extended detection hair drug testing or segmented hair drug testing see 13 panel hair drug test or 17 panel hair drug test panel)
