Recognized for its robustness, hair testing serves as a significant method to detect substance and alcohol consumption. Biomarkers get embedded in the fibers of a developing hair strand, showcasing a prolonged history of alcohol and other substances. When taken from near the scalp, hair offers a detection period of up to around three months for drugs and alcohol. Collecting hair is straightforward, moderately resistant to tampering, and uncomplicated to send.
A hair sample measuring 1.5 inches, comprising roughly 200 strands (similar in size to a #2 pencil) closest to the scalp, provides 100mg of hair, the preferred quantity for both screening and confirmation stages. For tests like EtG, add-ons, or more than 10 panels, a sample weighing 150mg is advisable. Using a jeweler’s scale to weigh the sample is suggested. If there is no scalp hair, an equivalent portion of body hair can be used. When mentioning head hair, it strictly refers to scalp hair. Conversely, body hair includes every other form of hair (such as facial, axillary, etc.).
Process Overview
The main stages involved in laboratory drug test processing comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about entering a sample into the lab’s system initially. The process confirms the sample's proper sealing and shipping, issues a random LAN (Laboratory Accessioning Number), and completes any missing data entry that wasn't supplied through an electronic chain of custody system.
Screening is the first prompt assessment for substance abuse. Although Screening is a budget-friendly approach to eliminate drug presence in most cases, a court-admissible result requires confirmation following a positive screen. Any presumptively positive samples in Screening necessitate secondary confirmation.
If a sample tests presumptively positive in the Screening phase, more hair is taken from the initial specimen for Extraction. This stage extracts drugs from hair at a significantly lower concentration than other methods like urine or oral fluid, which is why hair drug screening is considered the most challenging methodology.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, all presumptive positive samples undergo necessary washing. The comprehensive laboratory process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 certification.

Limitations:
Note: The test is often labeled as a "hair follicle test", but it evaluates the hair strand rather than the follicle beneath the scalp.
