Hair testing has emerged as an effective means for detecting drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug intake by capturing biomarkers within the strands' structure. By sampling close to the scalp, hair can indicate usage of alcohol and drugs over a span of roughly three months. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
An ideal sample for assessment and validation consists of a 1.5-inch section taken from about 200 hair strands (about the size of a #2 pencil) nearest the scalp, equating to 100mg. For tests like EtG, add-ons, or those exceeding 10 panels, it is advisable to gather 150mg of the hair sample. Applying a jeweler’s scale is suggested for specimen measurement. If scalp hair is missing, a comparable quantity of body hair may be utilized. References to head hair pertain solely to scalp hair, whereas body hair includes other types such as facial or axillary hair.
Process Overview
The laboratory processing of a drug test outcome comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial process of incorporating a sample into a laboratory's system. This process includes confirming proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any extra data input absent in an electronic chain of custody system.
Screening entails a preliminary inspection for drug use. Although Screening is a cost-efficient approach to eliminate drug consumption for the bulk of samples, a positive screening requires verification for legal admissibility. Samples that screen presumptively positive demand an additional confirmation process.
Should a sample presume positive during Screening, more hair is extracted from the originating specimen for Extraction, where drugs are drawn from hair at substantially lower concentrations than alternative methods (e.g., urine or oral fluid), making hair drug screening notably challenging.
Verification of any positive screening result occurs through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive undergo washing before Confirmation if necessary. The complete laboratory progression from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Note: Commonly labeled as "hair follicle tests," the test itself examines the hair strand rather than the follicle beneath the scalp
