Hair Follicle Drug Testing - Winchester, AR

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug usage by capturing biomarkers within the fibers of the growing hair shaft. Collected near the scalp, hair can show alcohol and drug use for up to about a 3-month period. Hair is easy to collect, somewhat challenging to tamper with, and straightforward to transport.

A 1.5-inch portion of around 200 hair strands (comparable to a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal sample amount for both screening and confirmation. For tests involving EtG, additional panels beyond 10, it's advisable to use 150mg of the specimen. Measuring the specimen on a jeweler’s scale is recommended. If scalp hair isn't available, a similar quantity of body hair can be gathered. When we mention head hair, it specifically refers to scalp hair, while body hair refers to other types of hair (like facial or axillary hair).

Process Overview

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

Accessioning includes the initial integration of a sample into a lab's system. This step verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not included by an electronic chain of custody system.

Screening entails a preliminary quick assessment for drugs of abuse. Although Screening is a cost-conscious method to exclude drug use for most samples, a positive screen must be validated to be permissible in court. Any samples testing positive in Screening require a follow-up confirmation.

If a sample is positive in the Screening phase, additional hair is taken from the original specimen for Extraction. Here, drugs are extracted at a lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.

To confirm any positive screening findings, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples testing positive are washed before confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation adheres to oversight under both the CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests reveal drug use for as long as 90 days, whereas urine tests have a shorter detection window.
• Difficult to manipulate: Cheating a hair drug test is quite difficult, enhancing the accuracy of the results.
• Historical data: It offers insight into a drug use pattern over time, not just recent consumption.

Limitations:

• Cannot detect recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically pricier compared to other drug testing techniques.
• Result variations: Elements like hair color and personal hair growth differences can influence the concentration of drug metabolites in hair.

Note: Despite being called "hair follicle tests," the test examines the hair strand and not the follicle beneath the scalp.
