Hair Follicle Drug Testing - Tye, TX

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair serves as a long-term record for alcohol and other drugs by capturing biomarkers within the fibers of the hair strand as it grows. When collected from near the scalp, hair can reveal drug and alcohol use over a duration of roughly three months. Collecting hair is straightforward, relatively resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches, consisting of about 200 hair strands (around the thickness of a #2 pencil) closest to the scalp, provides 100mg of hair, which is optimal for both screening and confirmation. For EtG assessments, additional evaluations, and/or tests exceeding 10 panels, a specimen weighing 150mg is advised. We suggest using a jeweler's scale to determine the specimen's weight. If scalp hair isn't available, an equivalent quantity of body hair may be taken. References to head hair specifically concern scalp hair, while body hair encompasses all other types (such as facial and axillary hair).

Process Overview

There are four primary stages in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab's system. This process includes ensuring the sample's proper seal and shipment, generating a random Laboratory Accessioning Number (LAN), and completing any supplementary data entry not facilitated by an electronic chain of custody system.

Screening entails a preliminary examination for substances of abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a confirmed positive screen is necessary for courtroom acceptance. Any samples deemed presumptively positive during Screening require a subsequent verification.

Should a sample be presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction process. At this point, drugs are removed from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug analysis is notoriously challenging.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples with presumptive positives are cleansed as required prior to confirmation. The entire lab procedure from Accessioning to Confirmation is evaluated per both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, while urine tests have a shorter detection span.
• Resistance to tampering: It's extremely challenging to tamper with a hair drug test, yielding more reliable outcomes.
• Records historical usage: It reveals a pattern of drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent consumption: Drug presence in hair becomes detectable roughly 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier than other testing forms.
• Results variability: Variables like hair color and individual differences in hair growth can influence drug metabolite levels in hair.

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