Hair testing is considered a potent means to identify drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug intake by embedding biomarkers into the fibers of the developing hair shaft. When obtained near the scalp, hair can deliver up to an approximate 3-month detection timeframe for alcohol and drugs. Collection of hair is straightforward, relatively hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches consisting of about 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, a 150mg sample is suggested. It's advised to weigh the sample using a jeweler’s scale. If scalp hair cannot be collected, a comparable quantity of body hair might be used. Head hair specifically refers to scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
There are four critical steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the primary processing of a sample into a lab's system. This step includes verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid check for drugs of abuse. Although Screening cost-effectively excludes drug usage in most cases, a positive result must be confirmed to be valid in court. Any sample that shows a presumptive positive during Screening needs further confirmation.
When a sample appears presumptively positive in the Screening phase, more hair is taken from the initial sample and prepped for Extraction. In this phase, drugs are extracted from hair at much lower concentrations compared to other methods (like urine or oral fluid), which is why hair drug testing is among the most challenging methods to perform.
Confirmation of any positive Screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with a presumptive positive result are cleansed before confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
