Hair Follicle Drug Testing - Theriot, LA

What it is, How it works

The use of hair testing is increasingly recognized as an effective approach for identifying drug and alcohol consumption. Hair can capture biomarkers within its fibers, offering a comprehensive history of substance use. By collecting hair near the scalp, it is possible to detect drugs and alcohol use for up to roughly 90 days. The collection process is straightforward, resistant to tampering, and easy to transport.

To conduct a thorough screening and confirmation, a 1.5-inch sample comprising approximately 200 hair strands (about the dimension of a #2 pencil) near the scalp is required, yielding a sample weighing 100mg. For tests involving EtG, add-ons, or more than 10 panels, a 150mg specimen is advised. It's best to use a jeweler’s scale for weighing the sample. If scalp hair isn’t available, a comparable amount of body hair can be utilized. The term "head hair" exclusively refers to scalp hair, while "body hair" encompasses all other hair types (including facial, axillary, etc.).

Process Overview

The processing of a drug test result in the laboratory entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the lab's system. This step involves confirming that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any other necessary data entry that an electronic chain of custody system hasn't already captured.

Screening is a preliminary assessment for possible drug abuse. While it provides a cost-effective method to eliminate drug presence in most samples, positive findings must undergo confirmation to be valid in legal scenarios. Samples that are presumptively positive during Screening must be confirmed through secondary analysis.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen and prepped for Extraction. In this stage, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening a complex methodology to execute.

Any positive results from Screening are confirmed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before Confirmation if necessary. The complete laboratory process, from Accessioning to Confirmation, undergoes review under the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Challenging to falsify: Cheating a hair drug test is notably difficult, which enhances result accuracy.
• Historical insight: It offers a usage pattern over time, instead of only recent usage information.

Limitations:

• Incapable of recent usage detection: Drugs take about 5-7 days to become traceable in hair.
• Expense: Hair drug tests tend to be pricier compared to other testing methods.
• Result variability: Elements like hair color and individual disparities in hair growth can influence the levels of drug metabolites in hair.

Note: Although often called "hair follicle tests", the actual analysis is conducted on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair Follicle Testing vs Urine Testing in Theriot, LA
In Theriot, the advantages of hair follicle drug tests are becoming increasingly apparent when compared to traditional urine tests. Hair testing offers superior detection accuracy and reliability, especially when assessing long-term substance use.
