Hair Follicle Drug Testing - Woodson, AR

What it is, How it works

Hair testing is acknowledged as an effective method in identifying alcohol and drug use. Hair archives a prolonged history, capturing biomarkers within the strands as they grow. When cut near the scalp, hair can reveal a detection span of up to 3 months for substances like alcohol. It's easy to collect, resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches and comprising approximately 200 strands—akin to a #2 pencil in thickness—yields about 100mg, which is ideal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a collection of 150mg is advised. It's suggested to measure the sample with a jeweler's scale. Should scalp hair be insufficient, an equivalent quantity of body hair can be used instead. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types, such as facial and axillary.

Process Overview

The procedure of processing a drug test in the lab includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is processed into the lab's system, ensuring it's sealed and transported correctly, assigning a LAN (Laboratory Accessioning Number), and completing any data entry omitted by an electronic chain of custody.

Screening acts as an initial rapid assessment for drug misuse. Although a cost-efficient method to dismiss drug presence in most cases, any positive results must undergo confirmation for court validity. Samples that test positive initially will require secondary confirmation.

If a sample is suspected positive during Screening, additional hair is extracted from the sample for Extraction. Here, drugs are isolated from the hair at a concentration much less than methods like urine or oral fluid, presenting hair drug screening as the most challenging to execute.

Positive screens proceed to Confirmation using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as positive receive a preliminary wash before confirmation. The lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, surpassing the shorter span of urine tests.
• Resistance to cheating: Cheating a hair drug test proves difficult, thus results are more reliable.
• Shows historical usage: It reveals drug use patterns over time, not just immediate usage.

Limitations:

• Inability to identify recent use: Drugs typically become detectable in hair after 5-7 days.
• Expense: Hair drug testing tends to be pricier than other testing techniques.
• Result variability: Hair color and growth differences may influence drug metabolite concentration.

Note: The term "hair follicle test" is often misused since the test examines the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle and urine drug tests in Woodson, AR, hair testing emerges superior in detection accuracy and reliability.
