Hair Follicle Drug Testing - Bristol, TN

What it is, How it works

Hair analysis has emerged as an effective means for detecting the use of drugs and alcohol. Hair captures a prolonged history of substance use by encapsulating biomarkers within the hair fiber during its growth. When obtained near the scalp, hair can offer a detection window of up to three months for both alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch sample comprising approximately 200 strands of hair (roughly the diameter of a #2 pencil) taken nearest the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests involving more than 10 panels, a specimen of 150mg is advisable. It's suggested to use a jeweler’s scale for weighing the sample. If scalp hair isn't available, a similar quantity of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The key phases in laboratory processing to derive a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the preliminary processing of a sample into the lab’s system. This procedure involves ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and inputting any extra data not handled by an electronic chain of custody process.

Screening performs an initial rapid check for substances of abuse. Although Screening is economical for ruling out drug use in most samples, a positive result necessitates confirmation to be acceptable in legal settings. Any samples that test presumptively positive during Screening demand secondary verification.

For samples that test presumptively positive in Screening, additional hair is extracted from the initial sample for the Extraction process. This phase involves extracting drugs from hair at substantially lower concentrations compared to other methods (like urine or oral fluid), which makes hair drug testing the most complex method.

Confirmation of any positive screening findings is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The entire laboratory progression from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings identify drug use for as long as 90 days, unlike urine tests which offer a shorter detection timeframe.
• Challenging to manipulate: Hair drug screenings are extremely tough to deceive, resulting in more precise outcomes.
• Historical pattern indication: They indicate drug use tendencies over time, rather than capturing only recent usage.

Limitations:

• Lacks detection for recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Generally, hair drug tests are pricier compared to other drug testing methods.
• Result variation: Elements like hair color and personal differences in hair growth can impact drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests", the testing actually involves the hair strand, not the follicle located beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Bristol, TN, hair follicle testing surpasses urine testing, offering numerous advantages. Hair tests illustrate a higher degree of accuracy by detecting substances consumed over a more extensive duration, making them superior. This reliability is essential for employers, ensuring a drug-free environment, and reducing the chances of false-negative results often linked with urine tests.
