Hair analysis is regarded as a valuable method for identifying substance and alcohol consumption. Hair records prolonged substance history by trapping biomarkers within the strands' fibers. When taken near the scalp-ends, hair offers up to roughly a 3-month timeframe for substance and alcohol identification. The collection of hair is straightforward, moderately challenging to tamper with, and convenient to transport.
A 1.5-inch length comprising roughly 200 hair strands (similar to the thickness of a #2 pencil), closest to the scalp, yields 100mg—an optimal quantity for testing and verification. For added tests such as EtG add-ons or those above 10 panels, a 150mg sample is advised. Employ a jeweler’s scale for accurate measurement. If scalp hair is not accessible, a similar volume of body hair is permissible. References to head hair imply only scalp hair, whereas body hair encompasses all other variants (facial, axillary, etc.).
Process Synopsis
The quartet of crucial stages in lab processing for substance testing comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a laboratory framework. This spans checking that the sample was correctly sealed and transported, assigning a non-specific LAN (Laboratory Accessioning Number), and executing any supplementary data entries absent in an electronic custody chain system.
Screening embodies a preliminary assessment for substances of concern. While Screening is a budget-friendly method to negate substance presence in most samples, validation of a positive screen is obligatory for court admission. Any samples deemed presumptively affirmative in Screening are needed to undergo further confirmation.
Should a sample be presumptively affirmative at the Screening stage, additional hair is extracted from the initial sample for Extraction. Here, substances are drawn from hair at much lower concentrations compared to alternative methodologies (e.g., urine or oral fluid), thus, rendering hair substance testing particularly challenging to execute.
Confirmation of any positive screening outcome is administered via GC/MS, GC/MS/MS or LC/MS/MS. Every presumptive positive sample undergoes a cleansing step before confirmation as necessary. The full lab procedure from Accessioning to Confirmation is scrutinized both under the CAP (College of American Pathologists) Hair categorization and the accreditation to ISO / IEC 17025 norms.
