Hair Follicle Drug Testing - Marshall, AR

What it is, How it works

Hair analysis has emerged as a vital means for identifying drug and alcohol usage. It offers a prolonged timeline of substance intake by trapping biomarkers within the hair's fibers. When cut close to the scalp, hair can reveal up to a three-month timeframe for alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch sample comprising around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, extra panels, and tests beyond 10 panels, a 150mg sample is advised. It is best to weigh the sample with a jeweler’s scale. If scalp hair isn’t available, the same amount of body hair can be used. When mentioning head hair, it refers solely to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample undergoes initial processing within the lab’s framework. This step ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input omitted by an electronic chain of custody system.

Screening serves as a preliminary check for drug abuse. Although it is cost-effective for eliminating drug usage in most samples, a positive screen requires confirmation for legal admissibility. Samples that are presumptive positive in Screening necessitate further confirmation.

Should a sample be presumptively positive at Screening, additional hair is extracted from the original sample for Extraction. This stage removes drugs from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to perform.

GC/MS, GC/MS/MS or LC/MS/MS methods confirm any positive screening result. All samples presumed positive are cleansed before confirmation if necessary. The complete laboratory procedure from Accessioning through Confirmation is evaluated under CAP (College of American Pathologists) Hair designation and validated against ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests detect drug usage for as long as 90 days, whereas urine tests offer a shorter window.
• Difficulty to cheat: Cheating a hair drug test is notably tough, enhancing result accuracy.
• Provides historical data: It reveals a drug use pattern over time, rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs require about 5-7 days to be traceable in hair.
• Cost: Hair drug tests usually incur higher costs than other methods.
• Variations in results: Differences such as hair color and personal growth rates can influence metabolite concentrations in the hair.

Note: Though often called "hair follicle tests", the examination is conducted on the hair strand, not the follicle beneath the scalp
