The utilization of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair serves as a chronological record of alcohol and drug intake by capturing biomarkers within the hair strand as it grows. When collected near the scalp, hair can offer up to a 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment comprising approximately 200 hair strands (roughly the dimension of a #2 pencil) from close to the scalp yields 100mg of hair, which is the optimal sample size for testing and validation. For EtG, additional evaluations, or tests exceeding 10 panels, a 150mg specimen is advised. We suggest weighing the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. When mentioning head hair, we are specifically referring to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into a lab's system. This step verifies that the sample was appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry not included in an electronic chain of custody system.
Screening involves an initial rapid assessment for illicit substances. While Screening offers a cost-efficient means to exclude drug use on most samples, a positive screen must be validated to be legally admissible. Samples showing presumptive positive results in Screening necessitate secondary confirmation.
If a sample appears presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. During this stage, drugs are isolated from hair at much lower concentrations than with other methods (e.g., urine or oral fluids), which makes hair drug screening the most challenging technique to execute.
Validation of any positive screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is examined under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Note: Although commonly termed as "hair follicle tests", the test itself examines the hair strand instead of the hair follicle beneath the scalp.
