Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substances by capturing biomarkers within the strands as they grow. A sample cut near the scalp can reveal evidence of drug or alcohol use for up to about a quarter of a year. Collecting hair is straightforward, resistant to tampering, and convenient for transportation.
Gathering a sample of 1.5 inches, approximately 200 hair strands (roughly pencil thick) nearest to the scalp provides 100mg, ideal for testing and verification. When testing for EtG, additional tests, or panels above 10, a 150mg sample is advised. Utilize a jeweler’s scale for precision. If scalp hair is absent, equivalent body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" covers all other hair types such as facial or underarm hair.
Process Overview
There are four primary stages in the lab processing of drug tests: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with entering the sample into the lab’s records, ensuring it was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional manual data needed beyond what the electronic chain of custody captures.
Screening offers a preliminary assessment for drug presence. It's a cost-efficient method for ruling out drug consumption in most cases. However, a positive result in Screening requires further confirmation to stand in legal settings. Samples deemed presumptively positive in Screening must go through an additional confirmation step.
Presumptive positives in Screening require more hair to prepare for Extraction. In this phase, drugs are removed from hair at a significantly lower concentration than other methods (e.g., urine or saliva), which is why hair testing is the most complex method.
GC/MS, GC/MS/MS, or LC/MS/MS devices are used for confirming positive Screening results. Samples that test positive initially are cleansed before confirmation if necessary. The complete lab protocol, from Accessioning to Confirmation, is reviewed under the CAP Hair designation and adheres to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Even though termed as "hair follicle tests", the assessment actually examines the hair strand itself, not the follicle beneath the scalp.
