Viewed as a robust method for detecting drug and alcohol consumption, hair testing offers an extended timeline of substance use by capturing biomarkers within the strands of growing hair. Harvested near the scalp, it offers a detection period of up to around 90 days for alcohol and drugs. Hair is easy to collect, tough to tamper with, and convenient to transport.
By taking a 1.5-inch sample comprising roughly 200 hairs (around the width of a #2 pencil) nearest to the scalp, you yield 100mg—ideal for both screening and confirmation. For EtG, extra tests, or those exceeding 10 panels, 150mg is advised. A jeweler’s scale should be used to weigh the sample. If scalp hair isn’t an option, an equivalent quantity of body hair can be obtained. "Head hair" pertains specifically to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
Four crucial steps in lab drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in processing a sample into the lab’s system, ensuring it was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any other necessary data entry absent from an electronic custody chain.
Screening provides an initial rapid check for drug abuse. While it offers a cost-effective way to discount drug use in most cases, any positive screen must be confirmed for court admissibility. Presumptive positive screenings necessitate a secondary confirmation.
Should the Screening phase suggest a positive result, additional hair is taken from the original sample for Extraction. Here, drugs are extracted from hair at concentrations lower than other methods (e.g., urine or oral fluid), explaining why hair screening is among the most challenging methods to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS methods perform Confirmation on any positive screening results. Presumptive positive samples undergo washing before confirmation as required. The entire lab procedure, from Accessioning to Confirmation, is subject to review under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Typically termed "hair follicle tests," the analysis focuses on the hair strand rather than the follicle beneath the scalp.
