Hair Follicle Drug Testing - Woodland, TX

What it is, How it works

Hair analysis has increasingly been recognized as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by embedding biomarkers within the growing hair fiber. When obtained near the scalp, hair can show a detection period of up to around 90 days for alcohol and other substances. Collecting hair is straightforward, not easily tampered with, and convenient for shipping.

A 1.5-inch hair section, consisting of roughly 200 strands (comparable in size to a #2 pencil), closest to the scalp results in 100mg of hair, which is the ideal amount for testing and validation. For EtG, additional testing, and/or testing beyond 10 panels, 150mg of hair is advised. It's advisable to use a jeweler’s scale to weigh the hair. Should scalp hair be unavailable, an equivalent amount of body hair can be used. 'Head hair' specifically refers to scalp hair, whereas 'body hair' includes all other varieties (facial, underarm, etc.).

Process Overview

The primary steps in processing a drug test in a laboratory are Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is first processed into the laboratory's system. This phase involves confirming the sample was sealed and sent correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional information not covered by an electronic chain of custody system.

Screening represents an initial examination for substances of abuse. Although Screening is a cost-effective method to negate drug usage for the majority of samples, a positive screen must be corroborated for court admissibility. Any samples that are presumptively positive at Screening need secondary validation.

Should a sample be presumptively positive during Screening, more hair is taken from the original specimen for Extraction. In this phase, drugs are extracted from hair at much lower concentrations than seen in other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to execute.

Confirmation for any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing before confirmation as needed. The laboratory procedure from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which have a more limited detection period.
• Challenges in manipulation: Hair drug tests are hard to forge, ensuring more reliable results.
• Trends in drug use: The tests can outline patterns of drug use over time, rather than just immediate usage.

Drawbacks:

• Inability to identify recent usage: Drugs take about 5-7 days to show up in hair.
• Expense: Hair drug screenings typically cost more than other testing approaches.
• Result variability: Aspects like hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Although these are often termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.
