Hair samples have become a crucial asset for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and other substances by securing biomarkers within the strands of the emerging hair. When procured near the scalp, it can reveal up to a quarter-year detection period for alcohol and other substances. Hair collection is uncomplicated, quite resistant to tampering, and straightforward to transport.
A 1.5-inch segment of roughly 200 strands (about the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for both screening and confirming. For EtG, add-ons, and/or more than 10-panel tests, 150mg of the specimen is advisable. We suggest using a jeweler’s scale for precise weighing of the sample. If scalp hair is not available, an equivalent quantity of body hair may be collected. When referencing head hair, we mean scalp hair only. Body hair pertains to any other hair forms (facial, axillary, etc.).
Process Overview
The sequence of laboratory processing for a drug test involves Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary entering of a sample into the lab’s framework. This phase includes confirming that the sample was correctly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and finishing any extra data entry that’s not available in an electronic chain of custody system.
Screening consists of an initial brief examination for illicit drug presence. While Screening offers an economical approach to excluding drug consumption in most samples, a custodial-ready positive result mandates formal confirmation. Samples with presumptive positive findings in Screening necessitate additional verification.
Should a sample produce a presumptive positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. In this process, drugs are isolated from hair in substantially lower concentrations than found in other techniques (e.g., urine or saliva), underscoring hair drug screening as the most complex methodology to execute.
Verification of positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples are cleansed before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair classification and the endorsement to ISO / IEC 17025 norms.

Note: Frequently mislabeled as "hair follicle tests", the procedure actually analyzes the hair strand itself, not the under-the-scalp follicle
