Utilizing hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair captures a lengthy chronology of both alcohol and drug usage by entrapping biomarkers within the developing hair fiber. When taken near the scalp, hair testing can offer a detection window of up to about 90 days for alcohol and drugs. Collection is straightforward, it is somewhat resistant to tampering, and transportation is simple.
A sample measuring 1.5 inches, composed of roughly 200 hair strands (comparable to a #2 pencil), nearest to the scalp will yield 100mg of hair, the preferred quantity for evaluation and validation. For EtG, additional checks, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It's advisable to use a jeweler's scale to weigh the sample. If scalp hair isn't available, an equivalent amount of body hair can be gathered. 'Head hair' refers specifically to scalp hair, while 'body hair' encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The key phases in the lab assessment of a drug analysis result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial integration into a laboratory's protocol. This involves confirming that the sample was correctly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding data input absent in the electronic chain of custody process.
Screening includes an initial swift evaluation for substances of abuse. While Screening is an economical approach to exclude drug usage in most samples, a positive screen necessitates confirmation to be deemed valid in legal proceedings. Samples indicating presumptive positives in Screening must undergo secondary confirmation.
Should a sample be identified as positive during the Screening phase, additional hair is extracted from the primary sample for Extraction. In this phase, drugs are isolated from hair at significantly lower levels than other procedures (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of any positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair design and accredited to ISO / IEC 17025 standards.
