Hair analysis is increasingly recognized as an effective means of identifying drug and alcohol consumption. The hair captures lasting records of alcohol and drug use by embedding biomarkers within the strands as they grow. When sampling hair close to the scalp, a detection period of up to roughly three months for alcohol and drugs can be achieved. Collecting hair is straightforward, fairly resistant to tampering, and easily transported.
A sample measuring 1.5 inches, consisting of around 200 hair strands (approximately the diameter of a #2 pencil), taken nearest to the scalp, yields 100mg of hair, which is optimal for testing. For EtG, additional tests, and/or assessments exceeding 10 panels, a specimen of 150mg is advised. The specimen should be weighed using a jeweler's scale. If scalp hair isn't obtainable, a similar quantity of body hair can be gathered. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
In the laboratory processing of a drug test result, the key phases include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into a laboratory’s system initially. This verifies the sample’s proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes data entry missing from an electronic chain of custody system.
Screening acts as a preliminary quick test for illicit substances, providing a cost-efficient method to exclude drug usage in most samples. However, a positive screen requires confirmation to be valid in legal settings. Samples indicating presumptive positivity during Screening necessitate a further confirmation step.
Should a sample test positive during Screening, additional hair from the original sample is utilized for Extraction. In this phase, drugs are extracted from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), which explains the complexity of hair drug screening as a method.
For confirming any positive Screening outcome, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Any samples with presumptive positive results undergo washing before confirmation as necessary. Every aspect of the laboratory procedure—Accessioning through Confirmation—is monitored under the guidelines of the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditations.
Advantages of hair drug testing:
Limitations:
Note: Although often labeled as "hair follicle tests", the test analyzes the hair strand rather than the hair follicle beneath the scalp.
