Hair analysis has emerged as an effective method for identifying alcohol and drug consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can offer an approximate 90-day detection period for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A sample measuring 1.5 inches, consisting of about 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp, will provide 100mg, which is the optimal sample mass for both screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, 150mg of the sample is preferable. Using a jeweler's scale is suggested for weighing the sample. If scalp hair is not available, a comparable amount from body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" includes all other types like facial or axillary hair.
Process Overview
The drug testing process in a laboratory encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial intake of a sample into the lab’s system, including verifying the proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody.
Screening is a preliminary assessment for drug abuse. Screening is a cost-effective approach for negating drug use in most cases, but a positive screen necessitates confirmation to hold up in legal contexts. Presumptively positive screenings require secondary validation.
If Screening indicates a presumptive positive result, additional hair is extracted from the sample for the Extraction phase. This involves extracting drugs from hair at much lower levels than other methods (e.g., urine or oral fluid), making hair drug testing notably challenging.
Positive results from screening are validated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleaned before confirmation as needed. The entire laboratory procedure from Accessioning through Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
