Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has gained recognition as an effective method for detecting drug and alcohol usage. The fibers of the growing hair strand encase biomarkers, offering a prolonged history of alcohol and other drug intake. Collected near the scalp, hair can offer a detection window for alcohol and other drugs of up to roughly 3 months. Hair collection is straightforward, tampering is challenging, and shipping is uncomplicated.
A sample of 1.5 inches, consisting of about 200 hairs (approximately the thickness of a #2 pencil) close to the scalp, provides 100mg of hair, the optimal amount for screening and validation. For EtG, supplementary tests, and/or panels exceeding 10, 150mg of the sample is advisable. Utilizing a jeweler’s scale for weighing the specimen is suggested. In the absence of scalp hair, a comparable quantity of body hair may be utilized. Head hair specifically refers to scalp hair alone. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab’s system. It involves confirming the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and executing any additional data entry absent from an electronic chain of custody system.
Screening performs an initial rapid evaluation for drugs of abuse. Although Screening is cost-effective for ruling out drug use in most samples, a confirmed positive screen is necessary for court acceptance. Samples tentatively positive in Screening need a secondary confirmation.
Should a sample indicate a positive result during the Screening phase, additional hair from the original specimen is readied for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than alternative methods (such as urine or oral fluid), underpinning the complexity of hair drug testing.
Any positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed if required before confirmation. The full lab procedure from Accessioning to Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
