Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by embedding biomarkers within the strands. When obtained near the scalp, hair can offer up to roughly a 3-month detection timeframe for substances. It is easy to collect, tricky to tamper with, and convenient to transport.
A 1.5-inch segment comprising roughly 200 hair strands (comparable to the girth of a #2 pencil) close to the scalp will yield 100mg, the preferred quantity for analysis and verification. For EtG extensions, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the sample with a jeweler’s scale. If scalp hair is not an option, the equivalent amount of body hair can be collected. By head hair, we specifically mean scalp hair. Body hair denotes all other hair types (such as facial, axillary, etc.).
Process Overview
The principal stages in laboratory processing of a drug testing sample involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary inputting of a sample into a lab’s system. This process encompasses verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data not captured by an electronic chain of custody platform.
Screening represents an introductory rapid test for drug presence. Although cost-efficient for eliminating drug presence in most samples, a positive screen necessitates confirmation for courtroom admissibility. Any samples showing presumptive positives at this stage require further confirmation.
If Screening indicates a presumptive positive, additional hair is taken from the original sample and processed for Extraction. During this phase, substances are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
To confirm any positive outcome from screening, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Presumptive positive samples are washed before confirmation as necessary. The complete laboratory workflow from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.

Limitations:
Note: Commonly termed "hair follicle tests", but the analysis targets the hair shaft rather than the follicle beneath the scalp.
