Hair Follicle Drug Testing - Reader, AR

What it is, How it works

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair serves as a record of alcohol and drugs over an extended period by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair testing can provide up to about a 3-month timeframe for detecting alcohol and drug use. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch portion of about 200 hair strands (roughly the size of a #2 pencil) closest to the scalp will yield 100mg of hair, serving as the ideal sample for testing and verification. For EtG, add-ons, and/or tests beyond 10 panels, 150mg of the sample is advisable. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair can be gathered. When discussing head hair, we specifically mean scalp hair. Body hair pertains to all other hair forms (facial, axillary, etc.).

Overview of the Process

The laboratory handling of a drug testing specimen consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial handling of a sample in a laboratory's system. This involves confirming the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. While Screening is an economical method to eliminate drug use for most samples, a positive result needs to be validated for court acceptance. Samples that test positive in Screening must undergo a subsequent confirmation.

If a sample tests positive in the Screening phase, additional hair is taken from the initial sample for Preparation. In this phase, drugs are extracted from hair at a significantly lower concentration than in other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. All samples testing presumptively positive are cleaned prior to confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Prolonged detection period: Hair drug analysis can reveal drug use for up to 90 days, whereas urine tests possess a shorter detection period.
• Resistance to tampering: Cheating a hair drug test is extremely difficult, ensuring more accurate results.
• Supplies historical insights: It can show a pattern of drug consumption over time, not merely recent usage.

Constraints:

• Incapable of detecting recent use: It takes roughly 5-7 days for drugs to be recognizable in hair.
• Expense: Hair drug analysis is typically costlier compared to other drug testing approaches.
• Outcome variations: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Despite the common term "hair follicle tests", the investigation actually examines the hair strand instead of the follicle located under the scalp.
