Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of growing hair, a hair sample offers an extended detection history for alcohol and substances. When sampled near the scalp, it can reflect drug and alcohol use over about a three-month duration. Gathering hair is straightforward, hard to tamper with, and convenient to mail.
A hair sample measuring 1.5 inches, roughly consisting of 200 strands (comparable in size to a #2 pencil) nearest to the scalp, totals around 100mg, which is the perfect quantity for both screening and verification. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the specimen is advisable. We advise using a jeweler’s scale to weigh the specimen. Should scalp hair be absent, an equivalent amount of body hair can suffice. The term head hair specifically denotes scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of a sample into a laboratory’s system. This involves validating proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any additional data entry that wasn’t covered by an electronic chain of custody.
Screening is a swift initial examination for drugs of abuse. While cost-effective for dismissing drug usage in most samples, a positive screen must be verified for court admissibility. All samples showing a presumptive positive in Screening necessitate a secondary confirmation.
In instances of a presumptive positive result during Screening, additional hair is extracted from the original specimen and prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other methodologies (such as urine or oral fluid), making hair drug analysis the most challenging process to execute.
Confirmation of any initial positive result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, if required. From Accessioning through Confirmation, the complete laboratory sequence adheres to CAP (College of American Pathologists) Hair standards and is accredited to ISO/IEC 17025 norms.

Note: Though commonly termed "hair follicle tests," the analysis focuses on the hair strand rather than the follicle beneath the scalp.
