Hair analysis is now recognized as an effective method for identifying alcohol and drug consumption. The inherent markers within hair strands provide a long-term record of substance use. If collected near the scalp, hair samples can potentially offer a 3-month window for detecting drugs and alcohol. Hair collection is straightforward, not easily tampered with, and convenient to transport.
A 1.5-inch section containing approximately 200 hair strands (akin to the width of a #2 pencil) near the scalp yields a 100mg sample, the optimal amount for both initial screening and subsequent confirmation. For EtG, extended panels, and/or tests exceeding 10 panels, a 150mg specimen is suggested. We advise using a jeweler's scale for weighing the sample. If the head hair is not available, an equivalent amount of other body hair can suffice. Here, head hair specifically refers to hair on the scalp, while body hair encompasses other types (facial, axillary, etc.).
Process Overview
The leading stages in lab processing for a drug test include Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is first logged into the lab's database. This step ensures the sample's proper sealing and shipping, assigns a non-sequential LAN (Laboratory Accessioning Number), and completes any supplemental data entry if not covered by an electronic chain of custody system.
Screening acts as an initial, quick examination for drug presence. Although Screening offers an economical approach to negate drug use for most samples, legal acceptance requires a positive result to be confirmed. Samples presumed to be positive in this phase need secondary confirmation.
Should results be positive in the Screening phase, additional hair is extracted from the original sample for the Extraction process. During Extraction, drugs are isolated from hair at a lower concentration compared to other methods (e.g., urine or saliva), thus making hair drug testing more technically challenging.
Positive findings from the screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed to be positive undergo a cleansing protocol prior to final confirmation. The entire lab process, from Accessioning to Confirmation, is conducted under the guidelines of both the CAP (College of American Pathologists) Hair certification and compliance with ISO / IEC 17025 standards.
