Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by embedding biomarkers within the fibers of the hair as it grows. When gathered from near the scalp, hair can deliver up to a roughly three-month detection period for alcohol and drugs. It is easy to gather, hard to tamper with, and simple to transport.
A sample size of 1.5 inches or about 200 hair strands, roughly equivalent to a #2 pencil's diameter, cut from the area nearest the scalp, will produce 100mg of hair, serving as the best sample for initial and confirmatory tests. For EtG add-ons and tests exceeding 10 panels, a 150mg specimen is favored. It's advisable to weigh the specimen on a jeweler’s scale. If head hair isn't available, a similar quantity of body hair may be used. Head hair indicates only scalp hair, while body hair includes other types like facial, axillary, etc.
Process Overview
The drug testing workflow encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preparation of a sample for entry into a lab's system. This step confirms the proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and addresses any missing data not captured by an electronic chain of custody protocol.
Screening constitutes a swift preliminary assessment for substance misuse. Although it's economical to exclude drug presence in most scenarios, a positive screen must undergo verification to hold legal merit. Each sample showing positive in Screening requires additional confirming steps.
On finding a presumptively positive result during Screening, additional hair is extracted from the primary sample for further testing. At this point, substances are extracted from hair in much lower concentrations than in other methods (e.g., urine or saliva), positioning hair drug screening as the most challenging methodologically.
Positive screening validations occur through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing preliminary positives are cleansed prior to their confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 certification standards.
