Hair Follicle Drug Testing - Calva, AZ

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair archives a comprehensive history of alcohol and other substances through the entrapment of biomarkers within the fibers of the maturing hair shaft. When harvested near the scalp, hair can offer a detection span for alcohol and other substances lasting up to roughly three months. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch segment consisting of around 200 hair strands (approximately the diameter of a #2 pencil) proximal to the scalp yields 100mg of hair, the optimum quantity for evaluation and validation. For EtG, supplementary tests, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. To ensure accuracy, measure the sample using a jeweler’s scale. If scalp hair is not present, an equivalent measure of body hair may be utilized. When referencing head hair, it specifically means scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Procedure Synopsis

The primary phases in the lab testing for drug detection are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample in the laboratory’s framework. This step includes ascertaining the correct sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input absent in an electronic chain of custody system.

Screening involves an expeditious initial check for substance misuse. Although Screening is a cost-efficient route to exclude substance use on most samples, positive results require confirmation for judicial acceptability. Samples yielding presumptive positives in Screening necessitate further confirmation.

Should a sample yield a presumptive positive at the Screening stage, additional hair is extracted from the original sample and readied for Extraction. At this juncture, substances are extracted from hair at considerably lower concentrations than alternative methodologies (e.g., urine or oral fluid), underscoring why hair drug screening is one of the most complex methodologies to conduct.

Confirmation of any positive Screening outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 accreditation standards.

Benefits of hair drug analysis:

• Prolonged detection duration: Hair drug analyses can reveal substance use for up to 90 days, unlike urine analyses which feature a briefer detection timeframe.
• Challenge to manipulate: It is exceedingly challenging to manipulate a hair drug test, enhancing result accuracy.
• Offers chronological data: It can provide a drug use trajectory over an extended timeframe, not just recent consumption.

Drawbacks:

• Inability to detect recent use: Detection in hair typically requires 5-7 days after usage.
• Expense: Hair drug analyses often incur higher costs than other testing methodologies.
• Result variability: Elements like hair pigmentation and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Commonly dubbed as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.
