Hair analysis is now regarded as a significant method for identifying drug and alcohol consumption. Hair keeps a prolonged history of substances by locking in biomarkers within the strands as they grow. When hair is obtained near the scalp, it can yield around a 3-month time frame for determining drug and alcohol intake. It is easy to gather, challenging to manipulate, and straightforward to send.
A 1.5-inch section including about 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp will constitute 100mg, which is an optimal amount for both screening and confirmation processes. For EtG, or tests exceeding 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for weighing the sample is recommended. If no scalp hair is present, a corresponding quantity of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The principal stages in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is introduced into a laboratory’s system. It involves checking that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry missing from an electronic chain of custody system.
Screening entails an initial quick evaluation for substances of abuse. It’s a cost-efficient approach for excluding drug presence in most samples; however, a positive result must be verified to be used legally. Any samples deemed presumptive positive in Screening need a secondary verification.
When a sample shows a presumptive positive result in the Screening phase, additional hair is extracted from the initial batch and prepared for Extraction. This phase involves isolating drugs from hair at a lower concentration than other techniques (e.g., urine or oral fluid), making hair drug analysis complex to conduct.
Positive screening results go through Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive are cleaned before Confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is examined according to both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Note: Although often called "hair follicle tests", the examination is performed on the hair strand, not the follicle beneath the scalp.
