Hair Follicle Drug Testing - Jonestown, MD

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extensive record by capturing biomarkers in the strands' fibers as they grow. Collected close to the scalp, hair offers a detection timeframe of up to 90 days for drugs and alcohol. Hair samples are easy to gather, difficult to tamper with, and simple to mail.

A sample size of about 1.5 inches consisting of roughly 200 hair strands (similar to the width of a #2 pencil) taken near the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advised. It's best to weigh the sample on a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. References to head hair imply scalp hair specifically, while body hair denotes all other types such as facial and axillary.

Process Overview

The primary laboratory stages for processing drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial entry of a sample into the lab's system, ensuring proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional information initially omitted by an electronic custody chain.

Screening performs a preliminary check for drug abuse. Although cost-efficient for excluding drug use in most cases, a positive Screening result requires subsequent confirmation for legal acceptability. Presumptively positive samples during Screening must undergo additional confirmation.

When a sample is tentatively positive at the Screening phase, more hair is extracted from the original specimen for the Extraction process. Here, drugs are isolated at much lower concentrations than with other methods (e.g., urine or oral fluid), which is why hair drug testing is among the most complex techniques to conduct.

Any positive finding in Screening is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The laboratory workflow from Accessioning to Confirmation is validated under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect drugs for up to 90 days, unlike urine tests with a shorter timeframe.
• Hard to tamper: Tampering with hair tests is complex, ensuring more reliable outcomes.
• Provides historical insights: It reveals usage patterns over time, not merely recent consumption.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair after around 5-7 days.
• Expense: Hair testing is usually costlier than other methods.
• Result variability: Factors like hair color and growth rate differences can influence metabolite concentrations in hair.

Note: While commonly termed as "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
