The use of hair testing has gained recognition as an effective method for identifying alcohol and drug consumption. Hair strands capture biomarkers within the growing hair fibers, allowing for a prolonged record of alcohol and substance usage. When collected near the scalp, hair can indicate substance use over a period of up to roughly three months for both alcohol and drugs. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches with approximately 200 strands of hair (similar in size to a #2 pencil) from the scalp usually produces 100mg, which is the optimal sample size for both screening and confirmation. For tests including EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be used. The term head hair specifically refers to scalp hair, while body hair includes all other types like facial and axillary hair.
Process Overview
The key steps in processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is organized into the lab's system, ensuring the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody system.
Screening involves a preliminary check for drugs of abuse. This step is cost-effective for ruling out drug use in many samples, but any positive screen must be confirmed for legal admissibility. Samples that indicate a positive result during screening need further confirmation.
When a sample tests presumptive positive in the Screening phase, additional hair is taken from the initial sample for the Extraction phase. Drugs are isolated from hair at concentrations lower than in other testing methods (such as urine or oral fluid), making hair drug screening a complex methodology to execute.
Confirmation for any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive are cleansed before confirmation if necessary. The entire process, from Accessioning to Confirmation, is vetted under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards for accreditation.
