Hair analysis is now recognized as an effective means to identify alcohol and drug consumption. Hair captures a long-standing record of substance usage by embedding biomarkers within the strands as they grow. When acquired near the scalp, hair can offer a detection range of approximately three months for substances. Collection is straightforward, it is somewhat challenging to tamper with, and it’s simple to transport.
A sample of 1.5 inches consisting of about 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, which is ideal for both screening and validation. For EtG, add-ons, or tests exceeding 10 panels, a specimen of 150mg is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not present, an equivalent quantity of body hair can be obtained. References to head hair explicitly imply scalp hair, whereas body hair encompasses all other hair types (like facial or axillary hairs).
Process Overview
The drug test laboratory procedure involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is first integrated into a laboratory's system. This process includes ensuring the sample is properly sealed and sent, assigning it a random LAN (Laboratory Accessioning Number), and fulfilling any additional data requirements absent in an electronic custody chain system.
During Screening, an initial rapid inspection for drug traces is executed. Screening serves as a budget-friendly method to dismiss drug use across most samples, but positive findings must be confirmed for court applicability. Any samples that test as presumptive positives in Screening necessitate an additional confirmation.
If a sample tests as a presumptive positive during Screening, further hair is extracted from the original specimen and readied for Extraction. Here, drugs are retrieved from hair at lower concentrations compared to other techniques (like urine or oral fluid), making hair drug screening the most intricate methodology to execute.
Any positive screening outcomes undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are washed before confirmation if required. The entire process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 standards.
