Hair examinations have increasingly become recognized as an effective method for identifying substance use of drugs and alcohol. Hair maintains an extended timeline of drug and alcohol intake by embedding biomarkers within the fibers of the hair strand as it grows. When sourced near the scalp, hair offers a detection period of up to roughly 90 days for substances. The collection process is straightforward, somewhat resistant to tampering, and easily transported.
A sample measuring 1.5 inches, comprising about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp, will produce 100mg of hair, which is optimal for testing and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. In cases where scalp hair is not available, a corresponding quantity of body hair can be used. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other varieties (beard, underarm, etc.).
Process Overview
The processing steps for a lab drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage where a sample is introduced into a lab's system. This step includes ensuring the sample's seal and shipment was conducted correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody.
Screening entails an initial examination for substances. Although Screening serves as an economical method for eliminating drug use in most samples, confirmation is required for results to be legally recognized. Samples with positive indications in Screening necessitate further confirmation.
If Screening suggests a positive result, additional hair is retrieved from the original sample for the Extraction phase. During this step, substances are extracted from hair at a significantly lower concentration compared to other testing methods (e.g., urine or saliva), establishing hair drug testing as one of the more challenging methodologies to execute.
Positive indications from Screening require Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples showing positive results are cleaned before Confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 certifications.
