Hair Follicle Drug Testing - Port Barre, LA

What it is, How it works

Hair testing is increasingly recognized as a significant method for detecting drug and alcohol consumption. Hair offers a prolonged historical record of drug and alcohol use by encapsulating biomarkers within the hair strand as it grows. If collected near the scalp, hair can offer an approximate 3-month window for detecting alcohol and other substances. Hair is easy to gather, relatively difficult to tamper with, and convenient to send.

A 1.5-inch sample of around 200 hairs (akin to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for testing and verification. For EtG, add-ons, or tests exceeding 10 panels, a sample of 150mg is advised. It's best to weigh the sample on a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair may be used. "Head hair" specifically refers to scalp hair, whereas "body hair" refers to all other types (facial, axillary, etc.).

Process Overview

The four primary stages in the laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step in integrating a sample into a lab’s protocol. This step verifies that the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional information not captured by an electronic custody system.

Screening provides a preliminary evaluation for substances of abuse. Screening offers an economical way to rule out drug use for most samples, though any positive screening results require confirmation to be legally admissible. Samples testing positive in Screening mandate further Confirmation.

For samples testing positive during Screening, additional hair is extracted from the original sample to prepare for Extraction. Drugs are extracted from hair at significantly lower concentrations compared to other testing methods (e.g., urine or saliva), highlighting the challenge of performing hair drug tests.

Any confirmed positive results from Screening undergo verification using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before Confirmation as required. All stages, from Accessioning to Confirmation, adhere to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, whereas urine tests detect recent use with a shorter period.
• Hard to manipulate: Hair drug tests are challenging to cheat, ensuring more reliable results.
• Provides usage patterns: It can show a history of drug use over time rather than immediate consumption.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing tends to be costlier than other testing methods.
• Test results may vary: Hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests," the analysis focuses on the hair strand, not the follicle itself under the scalp.
