Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. The hair records a prolonged history of drugs and alcohol by encasing biological markers within the strands as they grow. When trimmed near the scalp, hair can offer a detection period for approximately three months for alcohol and drugs. It is straightforward to collect, relatively resistant to tampering, and simple to transport.
A 1.5-inch section of around 200 hair strands (comparable in size to a #2 pencil) from the scalp delivers 100mg, the optimal quantity for analysis and verification. For EtG, supplementary tests, and/or assessments surpassing ten panels, 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not present, an equivalent volume of body hair might be gathered. The term head hair pertains solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Summary
The primary stages in laboratory processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the initial integration of a sample into the laboratory database. This entails confirming the proper sealing and transport of the sample, generating a random LAN (Laboratory Accessioning Number), and finalizing any extra data recording not managed by an electronic chain of custody system.
Screening is a preliminary, swift assessment for substance misuse. While it is an economical approach to eliminate drug use for most samples, a positive screen must be confirmed to be legally valid. Any samples with a presumptive positive in Screening require further confirmation.
If Screening suggests a positive result, additional hair is extracted from the original sample for Extraction. In this phase, substances are extracted from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), making hair analysis one of the most challenging techniques to execute.
Confirmation of a positive screen is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive result undergo washing before confirmation as required. The complete laboratory process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 guidelines.
Benefits of hair drug analysis:
Challenges:
Caution: While calls it "hair follicle tests", the examination focuses on the hair strand, not the follicle beneath the scalp.
