Hair Follicle Drug Testing - Highland Home, AL

What it is, How it works

Hair testing is increasingly regarded as a robust method for detecting drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can offer a detection window of up to about 3 months for alcohol and other substances. Hair is straightforward to collect, somewhat resistant to tampering, and easy to transport.

A 1.5-inch section consisting of roughly 200 hair strands (about the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal quantity for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't available, an equivalent volume of body hair is acceptable. When mentioning head hair, we refer solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four essential steps in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab’s system. This comprises verifying the sample’s seal and proper shipment, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not provided by an electronic chain of custody system.

Screening entails a preliminary quick evaluation for substances of abuse. While Screening is an affordable way to eliminate drug usage on most samples, a positive screen must be validated to be admissible in legal settings. Any samples that are presumptively positive in Screening necessitate secondary confirmation.

If a sample tests presumptively positive in the Screening phase, additional hair is extracted from the initial sample and set for Extraction. In this phase, drugs are isolated from hair at a substantially lower concentration than in other techniques (e.g., urine or oral fluid), which makes hair drug testing the most challenging methodology to execute.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The entire lab process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can identify drug use for as long as 90 days, in contrast to urine tests which have a briefer detection window.
• Hard to manipulate: Tampering with a hair drug test is notably difficult, ensuring more precise results.
• Yields historical data: It can show a pattern of drug use over time, not just recent usage.

Limitations:

• Unable to detect recent usage: It requires about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests tend to be more costly than other drug screening methods.
• Results variability: Variables such as hair color and individual differences in hair growth can influence the level of drug metabolites in the hair.

Note: While commonly called "hair follicle tests", the test itself examines the hair strand and not the hair follicle beneath the scalp
