Hair Follicle Drug Testing - Deweyville, TX

What it is, How it works

Hair analysis has gained recognition as an efficient means to uncover drug and alcohol consumption. Hair retains a prolonged history of substance use by embedding biomarkers within its fibers as it grows. When harvested near the scalp, hair offers a detection window of about three months for alcohol and drugs. Collecting hair is easy, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (akin to the thickness of a #2 pencil) cut nearest to the scalp yields 100mg of hair, ideal for both preliminary and confirmatory testing. When it comes to EtG, additional tests, and tests exceeding 10 panels, a sample size of 150mg is preferred. It is suggested to use a jeweler’s scale to measure the specimen. Should scalp hair be inaccessible, a similar quantity of body hair may be retrieved. "Head hair" specifically refers to scalp hair, while "body hair" pertains to hair from other areas (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results encompasses four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the sample’s initial processing into the lab’s system. It involves ensuring the sample’s seal and proper shipment, assigning it a random Laboratory Accessioning Number (LAN), and completing any data entry not available via an electronic chain of custody system.

Screening consists of a preliminary rapid test for drugs of abuse. Although Screening efficiently eliminates drug use in most samples, a positive screen necessitates confirmation for legal validity. Any samples testing presumptively positive during Screening require additional confirmation.

When a sample shows a presumptive positive during Screening, additional hair is drawn from the initial sample for Extraction. In this phase, drugs are isolated from hair at concentrations far lower than those in alternative methodologies (e.g., urine or oral fluid), making hair drug testing one of the most challenging techniques to execute.

Confirmation of any positive screen result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation, as needed. The comprehensive lab process, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace drug use up to 90 days, surpassing urine tests with shorter detection durations.
• Challenging to manipulate: Cheating a hair drug test is considerably difficult, enhancing the reliability of the results.
• Offers historical insight: Provides a timeline of drug use over time, extending beyond recent consumption.

Limitations:

• Inability to detect recent use: Detecting drugs in hair requires a period of approximately 5-7 days.
• Expense: Hair drug tests are typically pricier compared to other drug testing methods.
• Result variability: Factors like hair color and individual hair growth variations can impact drug metabolite concentrations in hair.

Note: Despite often being termed "hair follicle tests," the actual analysis targets the hair strand, not the scalp's hair follicle.
