Hair Follicle Drug Testing - Gaylesville, AL

What it is, How it works

Utilizing hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug intake by incorporating biomarkers within the strands of developing hair. When sampled near the scalp, hair offers an approximate detection span of up to three months for alcohol and drugs. The collection process for hair is straightforward, it is quite resistant to tampering, and it is convenient to transport.

A sample measuring 1.5 inches composed of approximately 200 hair strands (comparable in size to a #2 pencil) taken closest to the scalp will equate to 100mg of hair, which is the ideal sample size for both screening and validation. For tests like EtG, add-ons, and those extending beyond 10 panels, a specimen of 150mg is advised. It's suggested to weigh the sample on a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. The term body hair encompasses all other types (like facial, axillary, etc.).

Process Overview

The laboratory processing for a drug test result encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial incorporation of a sample into the lab's system. This encompasses ensuring the sample was sealed and shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and completing any supplementary data entry not captured by an electronic chain of custody system.

Screening acts as a preliminary rapid assessment for potential drug abuse. While it's a cost-efficient approach to exclude drug usage in most samples, a positive screening warrants a confirmation to hold up in legal proceedings. Samples with presumptive positive outcomes in Screening necessitate a follow-up confirmation.

In the event a sample shows a presumptive positive at the Screening stage, additional hair is extracted from the original specimen and prepared for the Extraction phase. Here, drugs are sourced from the hair at a significantly reduced concentration compared to alternatives such as urine or oral fluid, which explains why hair drug screening is among the more challenging methodologies to undertake.

Confirmation of any positive result from Screening is executed through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings undergo a pre-confirmation wash as needed. The entire lab process, ranging from Accessioning to Confirmation, is subject to review under the CAP (College of American Pathologists) Hair guidelines and adheres to ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Offers a lengthy detection span: Hair drug tests note drug usage up to 90 days, a notable contrast to urine tests with shorter detection periods.
• Challenging to tamper with: Hair drug tests present a significant challenge to cheat, thus enhancing result accuracy.
• Delivers historical usage insights: It outlines a pattern of drug use over an extended period, beyond just recent consumption.

Limitations:

• Incapable of detecting recent intake: There is a lag of about 5-7 days before drugs are traceable in hair.
• Expense: Hair drug tests typically bear a higher cost compared to other testing methods.
• Result inconsistencies: Variables such as hair color and individual hair growth variations may influence drug metabolite concentrations in hair.

Note: Despite the common reference to "hair follicle tests", the analysis focuses on the hair strand itself and not the follicle beneath the scalp.
