Hair analysis has gained recognition as an effective approach for identifying the use of drugs and alcohol. By embedding biomarkers into the strands of hair as they develop, it supplies extensive insights into the individual's consumption of alcohol and other substances. When taken near the scalp, hair can reveal alcohol and drug use up to roughly a three-month span. The collection process is straightforward, tampering is harder to accomplish, and it's convenient for shipping.
A sample measuring 1.5 inches, consisting of around 200 hair strands (similar in size to a #2 pencil) near the scalp, will yield roughly 100mg of hair—the optimal quantity for both screening and verification. For EtG, additional substances, and/or testing beyond a 10-panel, a 150mg sample is advisable. We suggest using a jeweler’s scale for accuracy. If scalp hair is absent, a comparable quantity of body hair can be used. When referencing head hair, we mean scalp hair specifically. Body hair covers all other kinds (facial, armpit, etc.).
Process Overview
The laboratory procedure for processing a drug test result includes four principal phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the lab's system. This step ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not captured by an electronic chain of custody system.
The Screening phase is a preliminary test for the presence of drugs of abuse. Though cost-effective and suitable for ruling out drug use in most samples, any positive result in this phase must be confirmed to be valid in legal contexts. Any samples indicating a presumptive positive in Screening must undergo a secondary confirmation process.
Should the Screening phase indicate a potential positive, additional hair from the specimen is utilized for Extraction. Here, drugs are extracted from the hair at significantly lower concentrations than those in alternative methods like urine or oral fluid tests, highlighting the complexity of hair drug screening.
Confirmation of any positive screening finding is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation as needed. The entire process—from Accessioning through to Confirmation—undergoes a review according to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
