Hair Follicle Drug Testing - Forest, VA

What it is, How it works

The evaluation of hair samples has emerged as an effective means of identifying drug and alcohol consumption. Hair fibers encapsulate biomarkers within the strands as they grow, providing a retrospective timeline of substance usage. When retrieved near the scalp, hair can offer a detection period of up to three months for both alcohol and drugs. It is straightforward to gather, relatively resistant to tampering, and straightforward to send.

A sample measuring 1.5 inches, containing roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal quantity for both screening and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg specimen is advisable. Utilizing a jeweler’s scale for weighing the specimen is suggested. In the absence of scalp hair, a comparable amount of body hair may be taken. When discussing head hair, we specifically mean scalp hair. In contrast, body hair encompasses all other forms (facial, axillary, etc.).

Process Overview

The four essential stages in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of the sample within a lab's framework. It involves verifying that the specimen was correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening conducts an initial rapid assessment for substance abuse. While it serves as a cost-efficient method to discount drug usage in most samples, a positive screening outcome requires verification to be credible in legal settings. Samples that initially test positive during Screening necessitate further Confirmation.

Should a sample test positive initially in the Screening phase, additional hair from the original sample is taken for Extraction. Here, drugs are extracted from hair at considerably lower concentrations than in other methodologies (e.g., urine or oral fluid), underscoring why hair drug testing is the most complex methodology to implement.

The Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples tentatively identified as positive undergo washing before confirmation, if necessary. The complete laboratory workflow from Accessioning through Confirmation is reviewed under both the CAP (College of American Pathologists) Hair distinction and adherence to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug assessments can trace drug usage for up to 90 days, as opposed to urine tests which offer a briefer detection duration.
• Challenging to circumvent: It is exceptionally difficult to tamper with a hair drug test, enhancing the reliability of results.
• Offers historical insights: It can delineate a timeline of substance use over an extended period, not just recent activity.

Limitations:

• Inability to detect recent consumption: Detection of drugs in hair takes approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically cost more than alternative drug testing methods.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

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

Why Hair Follicle Testing Beats Urine Testing

Superiority Over Urine Tests
The advantages of hair follicle evaluations surpass traditional urine testing methods, particularly in Forest, VA. These hair tests offer improved detection accuracy that urine samples simply cannot match, providing a more reliable overview of substance use history.
