Hair tests are now recognized as a formidable tool for detecting drugs and alcohol usage. Hair retains a timeline of alcohol and drug use by capturing biomarkers within the strands' fibers. When clipped near the scalp, hair offers a detection window for drugs and alcohol extending up to about 3 months. The collection process is straightforward, challenging to tamper with, and easy to transport.
Obtaining a 1.5-inch section of roughly 200 hair strands, similar in size to a #2 pencil, nearest the scalp will yield 100mg of hair, the optimal amount for both screening and confirmatory tests. For EtG, add-ons, or tests exceeding 10 panels, it's suggested to use 150mg of the sample. It's advisable to measure the sample on a jeweler's scale. Where scalp hair isn't available, a comparable quantity of body hair can be used. The term head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test proceeds through four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves introducing a sample into the lab's system. This includes confirming the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and filling any additional data gaps not covered by an electronic chain of custody system.
Screening acts as a preliminary rapid assessment for substances of abuse. It's an economical way to eliminate drug use possibilities for most samples, but a positive screening result must be confirmed to hold up in court. Samples that exhibit a tentative positive in Screening necessitate further confirmation.
Should a sample show a tentative positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are separated from the hair at a notably lower concentration compared to other methods (such as urine or oral fluid), which is why hair drug analysis is considered the most challenging method to conduct.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation as well as the accreditation to ISO / IEC 17025 standards.

Note: While commonly termed "hair follicle tests", the analysis actually focuses on the hair strand, not the follicle beneath the scalp.
