Hair testing is now regarded as a significant instrument for identifying drug and alcohol usage. Hair captures a prolonged history of alcohol and other substances, as biomarkers become embedded in the fibers of the hair that is growing. Hair collected near the scalp is capable of revealing drug and alcohol use over a roughly 3-month time frame. It is easy to collect, not easily tampered with, and straightforward to transport.
A hair specimen of 1.5 inches with around 200 strands (comparable to the diameter of a #2 pencil) from near the scalp will yield 100mg, an optimal amount for screening and confirmatory tests. For EtG, extra tests, and/or those with more than 10 panels, it is advised to use 150mg of sample. We suggest confirming the sample weight using a jeweler’s scale. If scalp hair is unavailable, an equal volume of body hair may be collected as a substitution. Reference to head hair pertains solely to scalp hair, whereas body hair includes other hair types (facial, axillary, etc.).
Process Overview
The procedure for processing drug test results in the lab encompasses four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is incorporated into a laboratory's system. This includes ensuring that the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data entry not included in an electronic chain of custody system.
Screening acts as an initial rapid assessment for substances of abuse. Though it offers a cost-effective approach to exclude drug use in most samples, a positive screening must be validated to be court-admissible. Any samples presumed positive during Screening require secondary verification.
When a sample tests positive in Screening, additional hair from the original sample is utilized and prepared for Extraction. In this phase, drugs are extracted from hair at significantly reduced concentrations compared to other tests (e.g., urine or oral fluid), which makes hair drug testing a highly challenging technique to execute.
Confirmation of any positive Screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before Confirmation, if necessary. The comprehensive laboratory procedure from Accessioning through to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
