Hair analysis has emerged as an effective method for detecting substance and alcohol consumption. The hair shaft captures biomarkers as it grows, which offers a historical account of drug and alcohol use. When collected near the scalp, hair can offer up to a three-month detection period for substances and alcohol. The collection process is straightforward, the risk of tampering is low, and shipping is simple.
A sample measuring 1.5 inches and consisting of about 200 hair strands (approximately the thickness of a #2 pencil) from the scalp equates to 100mg, the perfect amount for both initial testing and further verification. For EtG, additional tests, or panels exceeding 10, 150mg is suggested. It's advisable to use a jeweler’s scale to weigh the sample accurately. If scalp hair is not available, an equivalent quantity of body hair can be collected. "Head hair" specifically refers to hair from the scalp. "Body hair" encompasses other hair types like facial or axillary hair.
Process Overview
The drug testing laboratory workflow includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with logging the sample into a lab’s system. This step confirms proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any required manual data input not handled by electronic records.
Screening is a preliminary assessment for substance use. Although Screening is cost-efficient for ruling out substances in most samples, any positive result requires Confirmation for legal admissibility. Samples showing potential positives in Screening must undergo confirmation to be valid.
If a sample yields a potential positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, substances are isolated from hair at significantly lower concentrations than other methods like urine or oral fluid, highlighting the complexity of hair drug testing as a methodology.
Confirmation for any positive Screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before Confirmation as part of the process. The comprehensive procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
