Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a detailed record of substance intake by embedding biomarkers in the fibers of the developing hair shaft. When taken near the scalp, hair can offer a detection period of up to about three months for alcohol and other substances. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A hair section measuring 1.5 inches with approximately 200 strands (similar in thickness to a #2 pencil) closest to the scalp provides 100mg, which is the perfect amount for both initial screening and verification. For EtG, additional factors, and/or analyses beyond 10 panels, 150mg is advised. We suggest using a jeweler’s scale to weigh the hair sample. If scalp hair is not an option, a similar quantity of body hair can be used. The term "head hair" denotes only scalp hair. "Body hair" refers to all other types (facial, axillary, etc.).
Process Overview
The primary phases in the lab analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a lab’s database. This phase ensures the sample was adequately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry missing from an electronic chain of custody process.
Screening consists of an initial rapid assessment for substances of abuse. Although Screening is an economical means of excluding drug use in most specimens, a positive result necessitates confirmation to be valid in legal settings. Samples indicating a presumptive positive in Screening demand a subsequent verification.
Should a sample display a presumptive positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is one of the most complex processes.
Verification of any positive screen is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated with both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
