Hair analysis is now recognized as a potent method for identifying substance use, such as drugs and alcohol. By capturing biomarkers, hair offers a prolonged history of substance consumption within the strands. When sourced near the head, hair can reveal a usage timeline of up to roughly 90 days for alcohol and drugs. It is easy to collect, challenging to tamper with, and straightforward to transport.
A snippet of 1.5 inches, equating to approximately 200 hairs (similar to the width of a #2 pencil) next to the scalp, yields about 100mg—the optimal amount for analysis. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advised. Use a jeweler's scale for precise measurement. If scalp hair isn't available, a comparable quantity of body hair may be acquired. When discussing head hair, we mean only scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The drug test laboratory procedure involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is entered into the lab's system, ensuring it was properly packaged and sent, assigning a LAN (Laboratory Accessioning Number), and completing any additional required manual data input.
Screening is a preliminary assessment for drug traces. Though it is an economical method to exclude the presence of drugs in many samples, a positive result requires confirmation for legal credibility. Samples indicating potential positivity in Screening need further confirmation.
If the Screening stage reveals potential positivity, additional hair from the initial sample undergoes preparation for Extraction. In this phase, drugs are isolated from the hair at a much lower concentration relative to other testing forms (such as urine or saliva), underscoring the complexity of hair drug testing.
Positive results from Screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing presumptive positive are cleansed before confirmation when necessary. The entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation.
