Hair Follicle Drug Testing - Grayson Valley, AL

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying substance use. This approach offers a prolonged record of alcohol and narcotics consumption by capturing biomarkers within the growing hair fibers. When obtained near the scalp, hair can provide a detection timeframe of roughly three months for alcohol and other substances. The collection process is straightforward, presents challenges for tampering, and is conveniently shippable.

A 1.5-inch portion comprising approximately 200 strands closest to the scalp yields 100mg of hair, which is ideal for preliminary and confirmatory testing. For EtG, additional analyses, or panels exceeding ten, a specimen of 150mg is recommended. Utilizing a jeweler's scale is advisable for weighing the specimen. In cases where scalp hair is unavailable, collecting an equivalent volume of body hair is an option. References to head hair denote scalp hair exclusively, whereas body hair encompasses other types (such as facial and axillary hair).

Process Overview

The laboratory procedure for drug testing consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial intake of a specimen into the laboratory's system. This process includes confirming the proper sealing and shipment of the sample, assigning a LAN (Laboratory Accessioning Number) at random, and completing any additional clerical work not managed by an electronic custody system.

Screening provides a preliminary evaluation for substances of misuse. Although this approach is a budget-friendly mode for determining the absence of drugs in most specimens, a positive result requires substantiation to be considered valid in legal settings. Specimens with presumptive positive results in Screening necessitate further confirmation.

If the Screening stage suggests a positive result, additional hair is extracted from the initial specimen and prepared for the Extraction stage. Here, drug compounds are retrieved from hair at concentrations far below those used in alternative methods (e.g., urine or saliva), underlying the complexity of hair drug testing methodologies.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed for confirming any positive screening results. Prior to confirmation, samples with presumptive positives undergo washing as required. The entire lab sequence from Accessioning to Confirmation is vetted under the CAP (College of American Pathologists) Hair credential and the ISO / IEC 17025 accreditation standards.

Strengths of hair drug testing:

• Extended detection period: Hair analysis can trace substance use up to 90 days, while urine tests offer a briefer detection timeline.
• Resistance to evasion: Cheat attempts are particularly challenging with hair drug tests, enhancing result reliability.
• Chronological insight: This testing method maps out usage trends over time, unlike assessments that only capture recent consumption.

Drawbacks:

• No immediate detection: Hair requires 5-7 days post-use before drugs are discernible.
• Higher expense: This method generally incurs greater costs compared to alternatives.
• Result variation: Variables such as hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Despite the common label "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Grayson Valley, AL
Hair follicle testing far surpasses the traditional urine tests in terms of detection accuracy. This technique offers a longer detection window and is less prone to manipulation.
