Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drug exposure by embedding biomarkers within the fibers of the developing hair shaft. When sampled close to the scalp, hair can reveal a usage window of up to about three months for alcohol and drugs. It is easy to collect, fairly resistant to tampering, and simple to transport.
A 1.5-inch segment of around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for both screening and verification. For EtG, supplementary tests, and/or analyses exceeding 10 panels, 150mg of hair is suggested. We advise using a jeweler's scale for specimen measurement. If head hair is not accessible, a comparable quantity of body hair is acceptable. The term scalp hair specifically pertains to head hair. Body hair encompasses all other hair varieties (facial, underarm, etc.).
Process Overview
The laboratory procedure for drug test evaluation involves four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves receiving and integrating a sample into a lab’s system. This includes ensuring the sample was properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any additional data entry absent in an electronic chain of custody record.
Screening is a preliminary assessment for drug presence. Although Screening is a budget-friendly technique to exclude drug use in most samples, confirming a positive screen is required for legal admissibility. Samples with potential positive screens mandate further confirmation.
If a sample yields a potential positive result during Screening, additional hair is taken from the original sample and readied for Extraction. In this phase, hair undergoes extraction of drugs at much lower concentrations than found in other methods (e.g., urine or oral fluid), making hair drug analysis a challenging technique.
Positive screening results receive Confirmation using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation if needed. The complete lab process, from Accessioning through Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair classification and conforms to ISO / IEC 17025 accreditation standards.

Note: Referred to commonly as "hair follicle tests," the actual analysis targets the hair strand rather than the follicle beneath the scalp.
