Hair analyses are now recognized as an effective means for identifying drug and alcohol consumption. Hair archives long-term details of alcohol and drug intake by securing biomarkers within its fibers during growth. When extracted near the scalp, hair offers a detection period of up to three months for alcohol and other drugs. It is straightforward to collect, relatively tamper-resistant, and easy to transport.
A sample measuring 1.5 inches, with about 200 hairs (akin to the size of a #2 pencil) closest to the scalp, yields 100mg of hair, which is the preferred quantity for analysis and validation. For EtG, additional tests, or panels exceeding 10, a specimen weighing 150mg is advised. The use of a jeweler’s scale for measuring the specimen is recommended. In situations where scalp hair is not available, a similar amount of body hair can be taken. The term head hair pertains exclusively to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The drug testing procedure in the lab includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample gets processed into the lab's system. This step ensures the sample's seal and shipment were intact, allocates a random LAN (Laboratory Accessioning Number), and completes any remaining data entries absent in an electronic chain of custody framework.
Screening serves as an initial rapid assessment for drugs. Although Screening is an economical approach to exclude drug presence in most samples, a positive indication needs further validation to be legally admissible. Samples with alleged positive results in Screening must undergo a secondary confirmation.
Should a sample show presumptive positivity in Screening, additional hair is extracted from the original sample and prepped for Extraction. This phase retrieves drugs from hair at much lower concentrations than alternative methods (such as urine or oral fluid), emphasizing the challenge of hair drug screening.
Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Every sample with presumptive positivity undergoes washing before any required affirmation. The entire lab process, from Accessioning to Confirmation, is reviewed under the criteria of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
