Hair analysis is increasingly considered an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and substances by embedding biomarkers within the strands as they grow. When trimmed close to the scalp, hair can indicate alcohol and drug exposure up to roughly three months prior. Hair samples are easily obtained, hard to tamper with, and straightforward to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (akin to the size of a #2 pencil) taken nearest the scalp, offers 100mg—ideal for initial testing and confirmation. For EtG, additional screens, or tests over 10 panels, a 150mg sample is advised. It's recommended to measure the sample on a jeweler's scale. If scalp hair is lacking, a comparable quantity of body hair can be utilized. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (facial, armpit, etc.).
Process Overview
The lab process for reaching a drug test conclusion involves four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial handling of a sample upon entering a lab's system. This process confirms the sample's proper sealing and shipping, assigns it a unique LAN (Laboratory Accessioning Number), and fills in any extra data gaps not covered by an electronic custody system.
Screening consists of a preliminary substance abuse evaluation. Although Screening effectively rules out most drug use from many samples, any positive results need confirmation for legal validity. Samples flagged as presumptively positive in Screening require further verification.
If Screening results in a presumptive positive, additional hair from the original sample is processed for Extraction. During this phase, drugs are extracted at much lower concentrations compared to other methods (e.g., urine or oral fluid), which reasons why hair drug testing is one of the most challenging methodologies to execute.
Confirmation of positive screening outcomes is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives undergo washing before confirmation, as necessary. The full laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and accredited by ISO / IEC 17025 standards.
