Hair testing is recognized as an effective method for identifying alcohol and drug consumption. By capturing biomarkers within the hair's growing strands, it provides a comprehensive history of substance use. When taken from near the scalp, a hair sample can indicate drug and alcohol use for up to three months. The procedure is straightforward, not easily tampered with, and convenient to transport.
A sample measuring 1.5 inches and consisting of around 200 strands (similar in size to a #2 pencil) near the scalp will yield 100mg of hair, optimal for both screening and verification. For EtG, add-ons, and/or tests beyond 10 panels, a specimen weighing 150mg is preferred. It's advisable to measure the sample weight using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be collected. References to head hair imply scalp hair exclusively, whereas body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processes a drug test result through four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the first step of integrating a sample into the lab's system, ensuring that it was correctly sealed and delivered, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data not included by an electronic chain of custody.
Screening provides a preliminary assessment for drug abuse. It's an affordable method to dismiss drug use for most specimens; however, any positive outcomes necessitate confirmation for legal validity. Presumptive positive samples from Screening require further verification.
In cases where Screening results are presumptive positives, additional hair is retrieved from the initial sample for Extraction. This phase involves extracting drugs from hair at a notably lower concentration compared to other methods like urine or oral fluid, making hair drug screening particularly challenging.
Confirmation of positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo cleansing before confirmation as needed. The comprehensive lab process, from Accessioning through Confirmation, is evaluated following both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Note: Commonly termed as "hair follicle tests", these tests analyze the hair strand itself, not the follicle beneath the scalp
