Hair analysis is widely recognized as an effective method for identifying drug and alcohol consumption. The fibers of the hair strand capture biomarkers, providing a long-term record of substance use. Collected near the scalp, hair can offer a detection timeframe of up to three months for alcohol and drugs. Collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch hair sample, approximately 200 strands (around the size of a #2 pencil) closest to the scalp, yields 100mg of hair, the optimal sample for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. It's advisable to weigh the specimen using a jeweler’s scale. If scalp hair is unattainable, a corresponding quantity of body hair can be collected. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The lab process for drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent in an electronic chain of custody system.
Screening conducts an initial evaluation for substance use. Though cost-efficient for excluding drug usage in most cases, a positive screen requires confirmation to be legally valid. Samples presumptively positive in Screening must undergo secondary confirmation.
If positive in the Screening phase, further hair is extracted from the original specimen for Extraction. This stage removes drugs from the hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.
Positive screening results go through Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are washed before confirmation as necessary. The complete process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
