Hair analysis is increasingly regarded as a significant method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug intake by embedding biomarkers within the fibers of the expanding hair shaft. When collected near the scalp, hair can deliver a detection timeframe of up to roughly 3 months for drugs and alcohol. It is easy to gather, fairly challenging to tamper with, and straightforward to transport.
A 1.5-inch strand, comprising approximately 200 hairs (akin to the breadth of a #2 pencil) nearest the scalp, will yield 100mg of hair, making it an optimal sample for both initial and confirmatory testing. For EtG, add-ons, and tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler's scale for specimen measurement is recommended. Should scalp hair be inaccessible, an equivalent amount of body hair can be obtained. By head hair, we mean only the hair on the scalp, while body hair covers all other types (e.g., facial, armpit).
Process Overview
Lab processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the entry of a sample into a laboratory's system. It comprises verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not covered by an electronic chain of custody system.
Screening is a preliminary rapid assessment for misuse of drugs. Although Screening is a cost-effective approach to eliminate drug usage in most cases, court admissibility requires confirmation of a positive screen. Presumptive positives in Screening need a further confirmation step.
Upon a presumptive positive result during Screening, additional hair is extracted from the primary sample for the Extraction phase. During Extraction, drugs are retrieved from hair at far lower levels than other methods (e.g., urine or oral fluid), highlighting the technical complexity of hair drug screening.
Confirmed positive screenings are verified using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives are cleaned before confirmation as necessary. The comprehensive lab work from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 standard compliance.
Advantages of hair drug testing:
Limitations:
Note: Although often named "hair follicle tests," the exam actually evaluates the hair strand rather than the follicle beneath the scalp.
