Hair testing is now recognized as a potent method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use through biomarkers embedded in the strands as they grow. When clipped near the scalp, hair offers a detection timeframe of up to around 90 days for both alcohol and drugs. Collecting hair is straightforward, it's challenging to tamper with, and transporting it is uncomplicated.
A hair sample measuring 1.5 inches with approximately 200 strands (similar in diameter to a #2 pencil) nearest the scalp yields 100mg of hair, which is ideal for screening and confirmation. For EtG, additions, and tests exceeding 10 panels, a specimen weight of 150mg is suggested. The use of a jeweler’s scale for weighing the sample is advisable. If head hair isn't obtainable, an equivalent quantity of body hair may be taken. 'Head hair' is specifically scalp hair, whereas 'body hair' encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the sample processing in a lab's system. This process checks that the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any extra data input not included by an electronic chain of custody system.
Screening provides an initial rapid assessment for drug abuse. Although Screening is a budget-friendly way to exclude drug use in the majority of samples, a positive result must be confirmed for court acceptability. Samples that show a presumptive positive in Screening need a follow-up confirmation.
Should a sample be presumed positive during Screening, more hair is utilized from the original specimen for Extraction preparation. During Extraction, drugs are withdrawn from hair at significantly lower concentrations than other techniques (like urine or oral fluid), which makes hair drug screening particularly challenging.
Positive screening confirmations are performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 accreditation standards.

Limitations:
Note: Commonly misnamed "hair follicle tests", this test actually examines the hair strand rather than the follicle beneath the scalp.
