Hair testing is regarded as a valuable method for detecting drug and alcohol consumption. Hair captures a detailed record of alcohol and drugs by embedding biomarkers within its fibers as it grows. When sampled from near the scalp, hair offers an approximate 3-month window for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch hair sample containing around 200 strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, the optimal sample for analysis. For EtG, additional analyses, and tests exceeding 10 panels, a 150mg sample is advised. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair is not available, a similar amount of body hair can be gathered. Head hair refers specifically to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the lab’s system. This step verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and finishes any additional data entry not supplied by an electronic chain of custody system.
Screening conducts a preliminary rapid assessment for drug presence. While it is a cost-efficient means to exclude drug use in most samples, any positive screening must be confirmed for legal acceptance. Samples showing presumptive positive results require additional confirmation.
If Screening suggests a positive result, more hair is extracted from the sample for further Examination. This stage involves extracting drugs from hair at much lower concentrations compared to methods like urine or oral fluid, which makes hair drug testing particularly intricate.
Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair designation and aligned with ISO / IEC 17025 credentials.

Limitations:
Note: Commonly termed "hair follicle tests", the procedure evaluates the hair strand, not the follicle beneath the scalp.
