Hair analysis is now recognized as a robust method for identifying alcohol and drug usage. Hair strands capture biomarker evidence as they grow, offering a timeline of drug and alcohol consumption. When hair is sampled near the scalp, it can indicate substance use over roughly three months. The hair collection process is straightforward, hard to tamper with, and convenient for shipping.
A sample measuring 1.5 inches and consisting of around 200 hair strands, equating to a #2 pencil's girth, provides 100mg of hair, which is optimal for initial screening and subsequent validation. For extended panels or EtG add-ons, a specimen weight of 150mg is advisable. We suggest utilizing a jeweler’s scale for precise measurement. If head hair is not available, an equivalent quantity of body hair may be used. When we refer to head hair, we mean only scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The drug testing process in a laboratory consists of four crucial phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample is entered into the lab's system. The process ensures that the sample is properly sealed and transported, assigns it a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not covered by an electronic custody tracking system.
Screening serves as a preliminary fitness test for detecting substances of abuse. While it's an economical way to discount drug presence in most cases, a positive finding requires verification for legal admissibility. Any sample flagged as presumptively positive in Screening mandates further confirmation.
If Screening results in a presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. This stage involves isolating drugs from hair at significantly lower levels compared to other procedures (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.
Positive Screening outcomes are validated via GC/MS, GC/MS/MS, or LC/MS/MS. All samples labeled as presumptive positive undergo a cleansing step before confirmation as required. Every laboratory procedure from Accessioning through Confirmation is evaluated based on the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Note: Although widely called "hair follicle tests," the procedure examines the hair strand, not the follicle beneath the scalp.
