Hair testing is recognized as an effective means for identifying alcohol and drug use. Hair serves as a long-term record of intoxicants by capturing biomarkers within the strands as they grow. When sampled near the scalp, hair can offer a detection period for substances extending up to roughly 90 days. Hair is straightforward to collect, relatively resistant to tampering, and simple to transport.
A length of 1.5 inches from around 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp provides 100mg, ideal for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg is suggested. Using a jeweler's scale to measure the specimen is advisable. If scalp hair isn't available, a similar amount of body hair can be used. "Head hair" specifically indicates scalp hair, while "body hair" covers other types (facial, axillary, etc.).
Process Overview
The four primary phases in the lab processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the first step, integrating a sample into the lab's system. This process confirms the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry not provided by an electronic chain of custody system.
Screening offers a preliminary rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug consumption in most samples, court-admissible results require confirmation of any positive screen. Any samples presumed positive during Screening need subsequent confirmation.
When a sample is presumed positive during Screening, more hair is taken from the primary specimen for Extraction. In this step, drugs are withdrawn from hair at far lower concentrations than in alternative methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging technique to conduct.
The verification of any positive screening result is completed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if necessary. The complete lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Often termed as "hair follicle tests", the analysis directly targets the hair strand, not the follicle beneath the scalp.
