Hair Follicle Drug Testing - Wickett, TX

What it is, How it works

Hair testing is viewed as an effective method for detecting drug and alcohol consumption. Hair captures a prolonged record of alcohol and drugs by encasing biomarkers within the fibers of the advancing hair strand. When taken near the scalp, hair can reveal a detection window of up to roughly three months for alcohol and drugs. Hair is straightforward to collect, somewhat resistant to tampering, and easy to transport.

A 1.5-inch section of about 200 hair strands (comparable to a #2 pencil) closest to the scalp will yield 100mg of hair, which is the ideal sample for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the specimen is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not available, an equal amount of body hair may be utilized. Reference to head hair pertains solely to scalp hair. Body hair comprises all other hair types (facial, axillary, etc.).

Process Overview

The four principal phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary processing of a sample into a lab's system. This entails confirming that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry absent in an electronic chain of custody system.

Screening entails an initial rapid check for drugs of abuse. Although Screening is an economical method to exclude drug use in most samples, a positive result must be validated to be admissible in court. All samples that show presumptive positivity in Screening necessitate secondary confirmation.

If a sample demonstrates presumptive positivity during the Screening phase, more hair is extracted from the initial specimen and prepared for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration compared to other methodologies (e.g., urine or oral fluid), which is why hair drug screening is one of the most intricate methodologies to execute.

Confirmation of positive screening results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if required. The entire lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests that have a shorter detection window.
• Hard to cheat: It is quite challenging to cheat a hair drug test, resulting in more precise outcomes.
• Gives historical data: It can delineate a pattern of drug use over time, not merely recent usage.

Limitations:

• Cannot detect recent use: It takes roughly 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are typically pricier than other drug testing methodologies.
• Result variations: Variables such as hair color and individual disparities in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly referred to as "hair follicle tests", the test itself evaluates the hair strand and not the hair follicle beneath the scalp
