Hair sampling is acknowledged as an effective method for spotting substance and alcohol usage. By embedding biomarkers within the hair strand’s fibers, hair offers an extensive timeline of alcohol and drug activities. When obtained near the scalp, hair can reveal substance usage within an estimated three-month span. The collection of hair is easy, not easily tampered with, and straightforward to transport.
A sample consisting of 1.5 inches of approximately 200 hair strands (comparable to the diameter of a #2 pencil) from the scalp can provide 100mg of hair, which is the optimal sample size for precise analysis. For EtG, additional items, and/or tests exceeding ten panels, it is suggested to collect 150mg of the sample. It is advisable to measure the sample using a jeweler’s scale. In instances where scalp hair is not obtainable, an equivalent quantity of body hair is acceptable. References to head hair explicitly denote scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages involved in lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial incorporation of a sample into the lab’s framework. This includes confirming the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and finalizing any remaining data entry absent from an electronic chain of custody system.
Screening conducts a preliminary inspection for substances. While Screening is economically feasible for eliminating drug use in the majority of instances, a positive screen must be verified for court acceptance. Samples presumptively positive during Screening necessitate further confirmation.
Should a sample appear positive in Screening, additional hair is extracted from the initial sample for the Extraction process. In this stage, substances are extracted from hair at significantly lower concentrations compared to other methods (such as urine or saliva), making hair drug screening the most complex to execute.
Verification of any positive Screening result is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The complete lab protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
