Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the fibers of the growing hair strands. By collecting hair near the scalp, it offers up to a 3-month detection period for alcohol and drugs. Collecting hair is straightforward, relatively hard to adulterate, and simple to transport.
A 1.5-inch sample of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg, deemed the ideal sample size for screening and confirmation. For purposes of EtG, add-ons, or tests beyond 10 panels, it is advisable to use 150mg of the specimen. It is advisable to use a jeweler’s scale for weighing the specimen. Should scalp hair not be available, an equivalent quantity of body hair may be obtained. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The lab processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a specimen into a lab’s system. This includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not provided by an electronic chain of custody system.
Screening entails an initial rapid check for drugs. Although Screening is a cost-effective means to rule out drug use for most samples, a positive screen requires confirmation to be legally admissible. Samples that are presumptively positive in Screening necessitate secondary confirmation.
Presumptive positives in the Screening stage entail more hair being extracted from the initial sample for Extraction. In this step, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug testing is considered the most complex methodology.
Confirmation of positive screening results is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive specimens are cleansed as necessary. The complete laboratory procedure from Accessioning through Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Note: Though often termed as "hair follicle tests," the test itself examines the hair strand, not the follicle beneath the scalp.
