Hair Follicle Drug Testing - Cullen, LA

What it is, How it works

The perception of hair testing has evolved as an effective method for detecting drug and alcohol consumption. Hair strands capture a historical record of alcohol and illicit substances by embedding biomarkers within the fibers of the hair as it grows. When gathered from the scalp, hair can reveal a drug or alcohol-use timeline spanning up to three months. The sample collection process is straightforward, resistant to tampering, and convenient for transportation.

By collecting a sample of 1.5 inches, containing roughly 200 hair strands (about the girth of a #2 pencil) near the scalp, approximately 100mg of hair can be obtained, ideal for both initial screening and subsequent confirmation. For tests detecting EtG or beyond the standard 10 panels, about 150mg is advisable. Utilize a jeweler’s scale for precise measurement. In the absence of scalp hair, body hair of a similar amount can be used. "Head hair" refers explicitly to scalp hair, while "body hair" encompasses other types like facial and axillary hair.

Process Overview

The laboratory analysis of drug-testing follows four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing phase, integrating the sample into the laboratory's system. This stage prepares the sample by verifying its proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and completing any supplemental data inputs absent from an electronic chain of custody.

Screening serves as a swift initial examination for drug misuse. Though cost-effective for dismissing drug use in most cases, a positive screening result requires confirmation for legal acceptability. Presumptive positives in Screening must undergo further verification.

Upon a presumptive positive outcome in Screening, additional hair from the original sample is processed for Extraction. Unlike other methods (e.g., urine or oral fluid), hair extraction is performed at lower drug concentration levels, adding complexity to hair drug testing procedures.

Verification of a positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, copies of preliminary positive samples undergo necessary washing. The entire process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair Criteria and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Capable of indicating drug use for up to 90 days, outperforming the shorter detection span of urine tests.
• Fortified against manipulation: The integrity of hair drug test results is maintained by its resistance to manipulation.
• Informs historical usage: The test reveals prolonged patterns of drug use rather than only recent consumption.

Limitations:

• Inability to detect recent use: Hair takes approximately 5-7 days before drugs become traceable.
• Financial aspect: These tests generally incur higher costs in comparison to other drug testing methods.
• Result variability: Individual differences in hair color and growth rates can influence drug metabolite concentration levels in hair.

Note: Although commonly dubbed "hair follicle tests," the actual analysis targets the hair strand, not the follicle beneath the scalp.
