Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair captures biomarkers by encasing them in the fibers of the growing strand, providing a historical record of substance use. When sampled near the scalp, it can offer a detection window of roughly three months for drugs and alcohol. Collection of hair is straightforward, somewhat resistant to tampering, and simple to transport.
A sample measuring 1.5 inches consisting of around 200 hair strands (roughly the thickness of a #2 pencil) taken close to the scalp will yield 100mg of hair, which is optimal for screening and confirmation processes. For EtG, additional panels above 10, or special tests, a 150mg sample is advised. Use a jeweler's scale for accurate measurement. If scalp hair is not an option, an equivalent quantity of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types like facial and axillary hair.
Process Overview
The laboratory processing of drug test results involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, where a sample is processed into a lab's system. This process checks that samples are sealed and shipped correctly, assigns a random Laboratory Accessioning Number (LAN), and completes any extra data entry not available through an electronic chain of custody system.
Screening is a preliminary yet rapid check for abuse of drugs. While it is a cost-efficient approach to exclude drug use in most cases, a positive screen requires confirmation for legal admissibility. Samples that are presumptively positive during Screening need a follow-up confirmation.
If a sample is deemed presumptively positive during Screening, additional hair is taken from the original sample for Extraction. At this phase, extraction of drugs from hair occurs at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing challenging to execute.
Confirmation of any positive screen involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives undergo washing as necessary before confirmation. The lab process, from Accessioning to Confirmation, complies with both the College of American Pathologists (CAP) Hair criteria and ISO / IEC 17025 accreditation standards.
