Hair Follicle Drug Testing - Justin, TX

What it is, How it works

Hair testing has emerged as a significant method for identifying substance consumption. Hair retains a lengthy record of alcohol and drug usage by embedding biomarkers within the fibers of hair strands as they grow. When collected near the scalp, hair can reveal up to an approximately 3-month detection duration for substances. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.

A hair sample measuring 1.5 inches, consisting of roughly 200 strands (approximately the size of a #2 pencil), can provide 100mg, which is the optimal sample size for both screening and confirmation processes. For EtG, supplementary tests, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. Should scalp hair be unavailable, a similar quantity of body hair may be used. In the context of head hair, we specifically mean scalp hair. Body hair refers to all other hair types, including facial and axillary hair.

Process Overview

The lab processing of a drug test comprises four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial submission of a specimen into a laboratory's system. This stage includes checking that the sample was sealed and transported correctly, generating a random LAN (Laboratory Accessioning Number), and completing any additional data entry not provided by an electronic chain of custody.

Screening is a preliminary assessment for substance abuse. Although Screening is a cost-efficient method for excluding drug usage on most samples, a positive screen must be verified to be court-admissible. Samples that are tentatively positive during Screening require subsequent confirmation.

When a sample is arguably positive during the Screening phase, supplementary hair is extracted from the initial sample for further Extraction. In this phase, substances are isolated from hair at much lower concentrations than those in other testing methods (e.g., urine or oral fluid), making hair drug testing one of the more complex methods to execute.

The confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All tentative positive specimens undergo washing prior to confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is reviewed in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can trace substance usage up to 90 days, unlike urine tests, which have a more limited detection timeframe.
• High tamper resistance: It is exceedingly challenging to compromise a hair drug test, enhancing result accuracy.
• Offers historical insights: The test can reveal a history of drug usage over a prolonged period, not merely recent consumption.

Limitations:

• Incapacity to detect recent usage: Detecting drugs in hair requires approximately 5-7 days.
• Expense: Hair drug tests are typically more costly than alternative drug testing techniques.
• Result variability: Variables such as hair color and individual hair growth rates may influence the level of drug metabolites in the hair.

Note: Although often labeled as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle located beneath the scalp.
