Hair Follicle Drug Testing - North Laurel, MD

What it is, How it works

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair can retain a chronological history of substance use by embedding chemical markers within the fibers of the growing hair. By collecting samples near the scalp, hair can reveal up to around a 3-month period for detecting alcohol and substances. The collection of hair samples is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the optimal amount for testing and validating. For EtG, additional tests, and screenings beyond 10 panels, a 150mg sample is suggested. It's advised to weigh the sample using a jeweler's scale. If scalp hair isn't available, a similar quantity of body hair may be used. When talking about head hair, we mean scalp hair exclusively. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The drug testing in a lab encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the start of a sample's processing within a lab's framework. It involves ensuring proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and filling in any missing data not included in an electronic chain of custody record.

Screening provides a preliminary, rapid assessment for common drugs of abuse. Though economical for dismissing drug presence in most samples, positive screenings necessitate confirmation for legal acceptance. Samples found presumptively positive in Screening demand further verification.

If a sample tests presumptively positive during Screening, additional hair is extracted from the original sample to undergo Extraction. Here, substances are separated from hair at much lower concentrations compared to other methods (like urine or oral fluids), making hair drug testing particularly challenging.

Verification of any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing as needed before confirmation. The entire sequence from Accessioning to Confirmation is assessed following the CAP (College of American Pathologists) Hair accreditation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can uncover drug usage up to 90 days, unlike urine tests with shorter detection spans.
• Challenging to falsify: Hair drug tests are tough to manipulate, enhancing result accuracy.
• Tracks usage history: It reveals drug consumption over time, not just recent usage.

Limitations:

• Incapable of detecting recent use: Drugs become traceable in hair around 5-7 days post-use.
• Expense: Hair drug testing is often pricier compared to other testing techniques.
• Result variability: Factors including hair color and individual hair growth can influence drug metabolite concentrations in hair.

Note: Often termed "hair follicle tests," these tests assess the hair strand, not the follicle located under the scalp.
