Hair Follicle Drug Testing - Mcdougal, AR

What it is, How it works

Hair analysis is regarded as an effective method for detecting drug and alcohol use. Hair documents long-term substance use by capturing biomarkers within the strands of hair. Obtained near the scalp, hair can reflect up to a three-month timeline for substance use detection. It is straightforward to gather, quite resilient against tampering, and convenient to ship.

A 1.5-inch section encompassing about 200 hairs (approximately equivalent to a #2 pencil's width) closest to the scalp provides 100mg, the optimum quantity for screening and verification. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of hair is suggested. It's advisable to measure the hair sample using a jeweler’s scale. If scalp hair isn't accessible, a comparable amount of body hair is an alternative. When discussing head hair, this refers only to scalp hair. Body hair includes all other varieties (such as facial, underarm, etc.).

Process Overview

The primary stages in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the sample's initial integration into the laboratory framework. This stage includes ensuring the sample’s proper sealing and transportation, the assignment of a unique LAN (Laboratory Accessioning Number), and completing supplementary data entry not supplied via an electronic chain of custody system.

Screening represents a preliminary check for substance abuse. Although Screening is a cost-effective method to identify drug usage across most samples, positive screens must be validated for court admissibility. Any samples that yield a possible positive in Screening will necessitate further confirmation.

If a sample tests potentially positive in Screening, additional hair is sourced from the initial sample for Extraction. At this juncture, drugs are isolated from hair at significantly lower concentrations compared to other tests (like urine or oral fluid), highlighting the complexity of conducting hair drug screening.

Confirmation of any positive outcomes from Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All provisionally positive samples are cleansed before confirmation, as needed. The full lab procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Long detection span: Hair drug tests can reveal drug use up to 90 days, unlike urine tests which present a much shorter period.
• High difficulty to deceive: Tampering with hair drug tests is arduous, thus enhancing result accuracy.
• Tracks historical usage: It illustrates a timeline of drug use over an extended period, beyond just recent activity.

Limitations:

• Cannot detect recent consumption: Detecting drugs in hair takes around 5-7 days.
• Expense: Hair drug tests cost more than alternative drug testing techniques.
• Result variations: Variables like hair color and individual hair growth can impact the level of drug metabolites in the hair.

Note: Commonly termed "hair follicle tests", these tests actually examine the hair strand, not the follicle beneath the scalp.
