Hair analysis is increasingly recognized as an effective means for uncovering drug and alcohol consumption. Hair captures a prolonged record of substances by embedding traces within its fibers. When collected near the scalp, hair can offer an approximate detection period of up to 90 days for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising roughly 200 hair strands (equivalent to a #2 pencil's width) next to the scalp provides about 100mg, an optimal quantity for both screening and verification. For EtG, additional tests, or panels over 10, 150mg is advised. We suggest using a jeweler's scale to measure the sample. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. When mentioning head hair, we exclusively mean scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The drug testing analysis in a laboratory is comprised of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where the sample is incorporated into a lab's system by validating that it was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and inputting any other necessary data absent from an electronic chain of custody.
Screening initiates a preliminary evaluation for the presence of drugs. While Screening is a cost-efficient method for dismissing drug use in most samples, court-admissible results necessitate confirmation after a positive screen. Any samples found presumptive positive during Screening require further validation.
In cases where Screening reveals a presumptive positive, additional hair is taken from the initial batch for Extraction. This phase isolates drugs from hair at a significantly lower concentration than other methods (such as urine or oral fluid), highlighting why hair drug analysis is one of the most complex methodologies.
Any positive Screening outcomes are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing prior to confirmation if needed. The complete lab procedure from Accessioning through to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 credentials.
