Hair Follicle Drug Testing - Prairie View, TX

What it is, How it works

Hair analysis is now recognized as an effective means for detecting substance use of drugs and alcohol. Hair serves as a long-term indication of alcohol and other drug consumption by embedding biomarkers within the fibrous structure of the growing hair. When gathered near the scalp, hair can reveal a detection period for alcohol and drugs of approximately three months. Hair is easy to gather, somewhat tamper-resistant, and convenient to transport.

A 1.5-inch section consisting of around 200 hairs (similar in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation. For tests like EtG and those requiring over 10 panels, a 150mg specimen is advisable. We suggest using a jeweler's scale to weigh the sample. In cases where scalp hair is unavailable, an equivalent amount of body hair can be utilized. When we mention head hair, it is specific to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The drug test result's laboratory processing comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with entering a sample into a lab’s system. This step checks if the sample was sealed and transported appropriately, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by an electronic chain of custody system.

Screening performs a preliminary rapid check for substances of abuse. While this is a cost-effective method to rule out drug consumption in most cases, a positive screen must be validated to be usable in legal settings. Presumptively positive samples in Screening require subsequent confirmation.

When a sample screens as presumptively positive, additional hair is obtained from the original sample to prepare for Extraction. During this phase, substances are extracted from hair at much lower concentrations than other methods (like urine or oral fluid), making hair drug screening the most challenging to conduct.

Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples thought to be positive undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect substance use for up to 90 days, compared to the shorter detection span of urine tests.
• Difficulty to cheat: Cheating on a hair drug test is extremely challenging, resulting in more reliable outcomes.
• Provides historical data: It outlines a pattern of substance use over a duration, rather than capturing only recent use.

Limitations:

• Cannot detect recent use: It takes around 5-7 days for drugs to become evident in hair.
• Cost: Hair drug tests are typically pricier than other drug testing approaches.
• Variations in results: Aspects such as hair color and individual hair growth differences may influence the drug metabolite concentration in hair.

Note: Though often termed as "hair follicle tests", the analysis focuses on the hair strand rather than the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing
