Hair Follicle Drug Testing - Holts Corner, TN

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a chronological record of alcohol and drug activity by embedding biomarkers within the fibers of the developing hair strand. Positioned near the scalp, hair can offer nearly a 90-day timeframe for identifying the use of alcohol and drugs. Collection of hair is straightforward, relatively resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, containing approximately 200 hair strands (akin to the size of a #2 pencil) nearest the scalp, will produce 100mg of hair, the optimal quantity for both screening and confirmation. For assessments like EtG, additional tests, and those exceeding 10 panels, 150mg of hair is advisable. Using a jeweler's scale for specimen weighing is suggested. In cases where scalp hair is inaccessible, an equivalent volume of body hair may be used. The term head hair specifically indicates scalp hair, whereas body hair denotes all alternative hair types (like facial and axillary).

Process Overview

The key phases in the laboratory analysis of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of introducing a sample into a lab's system. This stage involves validating the sample's sealing and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody system.

Screening entails an initial rapid evaluation for the presence of drugs. Though Screening is an economical strategy for dismissing drug presence in most samples, any positive result from Screening necessitates a confirmation to be legally viable. Samples with a presumptive positive screening require a subsequent confirmation test.

For any sample testing positive at the Screening phase, additional hair is extracted from the initial portion and readied for Extraction. Here, drugs are isolated from hair at a significantly lower concentration compared to other test methods (e.g., urine or oral fluid), which makes hair drug screening a highly challenging technique to execute.

Confirmation of any positive screen outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are washed prior to confirmation if required. The comprehensive lab process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation in line with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the ability to identify drug use for as long as 90 days, while urine tests have a shorter timeframe.
• Low possibility of evasion: The likelihood of falsifying a hair drug test is minimal, therefore enhancing result reliability.
• Historical pattern analysis: It provides insight into drug usage trends over time, beyond current use.

Limitations:

• Incapability to detect recent intake: Detection of drugs in hair typically starts around 5-7 days post-use.
• Higher expense: Hair drug tests are often pricier than alternative testing approaches.
• Variable outcomes: Influences such as hair color and individual growth rates may alter drug metabolite concentration.

Note: Despite being often referred to as "hair follicle tests," the analysis targets the hair strand rather than the follicle beneath the scalp.
