Hair Follicle Drug Testing - Lafayette, AL

What it is, How it works

The utilization of hair testing has garnered recognition as a potent method for identifying substance and alcohol consumption. Hair retains a prolonged record of drug and alcohol usage by capturing biomarkers within the fibers of the growing strand. When acquired near the scalp, hair can offer nearly a 3-month timeframe for drug and alcohol detection. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.

A sample of 1.5 inches containing around 200 hair strands (about the thickness of a #2 pencil) near the scalp yields approximately 100mg of hair, which is the perfect quantity for testing and validation. For EtG, additional tests, and/or panels above 10, 150mg of hair is advised. It’s suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair may be utilized. When discussing head hair, it specifically pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result primarily comprises four stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning focuses on integrating the sample into the lab’s system initially. This step includes confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing additional data entry not covered by electronic chain of custody processes.

Screening conducts a primary swift examination for substances. Although Screening is an economical method for dismissing drug usage in most samples, a positive result demands confirmation to be legally defensible. Samples that test presumptively positive require further confirmation.

In cases where a sample tests positive in the Screening step, more hair is processed from the initial sample for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging to execute.

Confirmation of positive Screening results is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples testing presumptively positive undergo washing before confirmation if necessary. Each phase, from Accessioning to Confirmation, is thoroughly reviewed under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which have a limited detection period.
• Challenging to deceive: It is nearly impossible to falsify a hair drug test, ensuring more reliable results.
• Supplies historical information: It can reveal a pattern of drug use over time, not solely recent consumption.

Limitations:

• Undetectable recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are generally pricier than other drug testing methodologies.
• Result variability: Elements such as hair color and individual hair growth differences can impact drug metabolite levels in the hair.

Note: Commonly termed "hair follicle tests," the examination assesses the hair strand rather than the follicle beneath the scalp
