Hair sampling is now regarded as a potent method for identifying drug and alcohol consumption. It offers an extensive timeline of substance use because biomarkers become embedded in the strand as the hair grows. When clipped near the scalp, it reveals up to roughly three months of activity regarding alcohol and drug ingestion. Collecting is straightforward, making tampering challenging, and transportation uncomplicated.
A 1.5-inch batch, roughly equivalent to 200 hair strands (comparable to the circumference of a #2 pencil), collected nearest the scalp, yields 100mg, which is optimal for guided screening. For screening of EtG, enhanced tests, or those exceeding 10 panel levels, a 150mg portion is advisable. It's best to measure the sample with a jeweler’s scale. Should scalp hair be lacking, an equal portion of any bodily hair is acceptable. By "head hair", we mean scalp-specific strands. Conversely, "body hair" encompasses all other hair types, such as facial and axillary.
Process Overview
The laboratory analysis of drug tests encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample undergoes initial processing to enter a laboratory's system. This step includes ensuring the sample's secure shipment and sealed integrity, attributing a unique LAN (Laboratory Accessioning Number), and imputing any additional data absent from the electronic chain of custody.
Screening provides a rapid assessment for drug presence. It's efficient for excluding drug usage in numerous samples, yet to ensure legal admissibility, a positive screening must undergo further validation. Any sample potentially positive during Screening demands another level of confirmation.
A presumptive positive in Screening prompts further analysis. More hair is extracted for the Extraction phase, with substances removed at concentrations much lower than those in other testing forms (e.g., urine, oral fluid), making hair testing the most challenging to implement.
To validate any positives from Screening, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples flagged as presumptively positive are cleaned prior to confirmation if required. The entire laboratory cycle from Accessioning to Confirmation undergoes review per the CAP (College of American Pathologists) Hair specifications and ISO/IEC 17025 accreditation.
