Hair Follicle Drug Testing - Wilsons, VA

What it is, How it works

The recognition of hair testing as a robust method for detecting alcohol and drug consumption has grown significantly. Hair captures biomarkers within its growing strands, providing a comprehensive timeline of substance usage. When gathered near the scalp, this method offers approximately a 90-day detection period for alcohol and other drugs. Hair is uncomplicated to collect, relatively resistant to tampering, and straightforward to transport.

A sample of 1.5 inches, encompassing about 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for screening and verification. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the specimen is advisable. Using a jeweler’s scale for precise measurement of the specimen is suggested. In cases where scalp hair is scarce, an equivalent amount of body hair may be used. 'Head hair' specifically pertains to scalp hair, while 'body hair' includes all other types (facial, axillary, etc.).

Process Overview

Four primary stages are involved in the laboratory handling of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the sample's initial integration into the laboratory system. This step encompasses confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry absent from an electronic chain of custody system.

Screening serves as an initial cursory examination for drug use. Although Screening is a budget-friendly method to exclude drug usage in most samples, a positive screening must be confirmed for legal admissibility. Samples preliminarily positive in Screening necessitate a further confirmation.

Should a sample test presumptively positive during the Screening stage, additional hair is extracted from the original specimen and processed for Extraction. This phase involves removing drugs from hair at notably lower concentrations than alternative methods (e.g., urine or oral fluid), underscoring the challenge of hair drug screening.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are cleansed before confirmation as required. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter window.
• Resistance to manipulation: Cheating a hair drug test is highly difficult, enhancing result accuracy.
• Tracks historical use: This method outlines drug usage patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent usage: It takes approximately 5-7 days for drug presence to appear in hair.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Variability in results: Elements such as hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Although often mislabeled as "hair follicle tests", the analysis targets the hair strand, not the follicle situated beneath the scalp.
