Hair Follicle Drug Testing - Walnut Cove, NC

What it is, How it works

Hair analysis has emerged as an effective method in identifying the use of drugs and alcohol. Hair acts as a long-term record of drug and alcohol intake by embedding biomarkers within the strands as they grow. Sampled near the scalp, hair can offer a detection timeline stretching up to roughly 3 months for both alcohol and various drugs. Collecting it is straightforward, it's fairly resistant to tampering, and it can be transported with ease.

A hair sample of 1.5 inches, approximately 200 strands (comparable to a pencil's #2 diameter), taken nearest to the scalp, yields 100mg of hair—a prime amount for both screening and confirmation. For tests like EtG and those exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the hair sample using a jeweler’s scale. If scalp hair is missing, the same quantity of body hair can be substituted. When discussing head hair, it specifically pertains to scalp hair, while body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The drug test laboratory procedure comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample’s preliminary integration into the lab’s database. This process ensures proper sealing and shipping of the sample, assigns it a random LAN (Laboratory Accessioning Number), and fills in any missing data that isn't covered electronically.

Screening performs an initial swift assessment for substances of abuse. While it’s a cost-effective method for disqualifying drug presence in most samples, any positive screening requires confirmation for legal acceptability. Samples that test positive in Screening necessitate a secondary confirmation.

A sample indicated as positive in the Screening phase will have additional hair drawn from the initial collection for Extraction. During Extraction, drug substances are retrieved from hair at significantly lower levels compared to other methods (e.g., urine or oral fluid), illustrating why hair drug testing is renowned for its complexity.

Verification of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if needed. The entire test process from Accessioning to Confirmation is accredited under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests can reveal drug consumption up to 90 days, unlike the shorter timeframe of urine tests.
• Challenging to falsify: The difficulty in deceiving a hair drug test enhances its result accuracy.
• Displays historical usage: It outlines drug consumption patterns over time, not solely recent usage.

Limitations:

• Incapable of detecting recent consumption: Drugs typically become noticeable in hair after roughly 5-7 days.
• Expense: Hair drug testing is typically costlier compared to other testing methods.
• Variable outcomes: Elements like hair color and personal growth rates can influence drug metabolite concentrations in hair.

Note: While often dubbed "hair follicle tests", the actual examination is performed on the hair strand, not the follicle beneath the scalp.
