Hair Follicle Drug Testing - Vair, TX

What it is, How it works

Hair assays are regarded as a potent mechanism for the identification of drug and alcohol consumption. Hair offers an extended retrospective analysis of substances by embedding biomarkers within the strands as they develop. When obtained near the scalp, hair can reveal up to around a 3-month timeframe for detecting alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and facile to transport.

A sample of approximately 1.5 inches comprising roughly 200 strands of hair (comparable to a #2 pencil in thickness) closest to the scalp yields 100mg of hair, the optimal sample size for preliminary and confirmatory tests. For EtG, additional testing, and/or analyses exceeding 10-panel, 150mg of the sample is advised. It is recommended to measure the sample with a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair might be gathered. References to head hair uniquely imply scalp hair, whereas body hair encompasses all alternate hair varieties (facial, axillary, etc.).

Process Overview

The quartet of primary stages in laboratory handling of a drug test outcome comprises Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a laboratory’s framework. This process confirms the sample was properly sealed and dispatched, allocates a unique LAN (Laboratory Accessioning Number), and fulfills any supplementary data input absent from an electronic custody tracking system.

Screening involves a preliminary rapid appraisal for the presence of narcotics. While Screening remains a fiscally efficient method to exclude drug consumption in a majority of specimens, a positive outcome necessitates subsequent confirmation for legal admissibility. Samples yielding presumptive positive results in Screening mandate a follow-up affirmation.

Upon a presumptive positive indication in the Screening phase, additional hair is extracted from the initial specimen for Preparation in the Extraction phase. Here, substances are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), underscoring hair drug testing as the most challenging technique.

Confirmation of any positive Screen result is executed utilizing GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive specimens undergo washing pre-confirmation if required. The laboratory-wide procedure from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection interval: Hair drug assays can recognize drug consumption up to 90 days, in contrast to urine tests which have shorter detection periods.
• Fraud deterrence: Hair tests are notably difficult to manipulate, enhancing result precision.
• Yields usage narratives: It offers an impression of drug use over time, instead of isolating recent usage.

Limitations:

• Lacks recent detection: It generally takes 5-7 days for drugs to become visible in hair samples.
• Expense: Hair drug assays tend to be pricier than alternative testing procedures.
• Outcome variability: Factors like hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Although often called "hair follicle tests", this analysis evaluates the hair strand, not the beneath-the-scalp follicle.
