Hair Follicle Drug Testing - Crisfield, MD

What it is, How it works

Hair testing is recognized as a robust mechanism for identifying drug and alcohol consumption. Hair captures long-term traces of alcohol and drugs by embedding biomarkers within the hair's growing fibers. A sample taken near the scalp can offer a detection period of up to roughly 3 months for substances like alcohol. Hair is easy to gather, challenging to tamper with, and straightforward to ship.

A 1.5-inch portion of roughly 200 hair strands (approximate diameter of a #2 pencil) located nearest to the scalp yields 100mg of hair, which is the perfect amount for both screening and confirmation. For EtG, additional tests, and/or analyses beyond 10 panels, a larger 150mg specimen is advisable. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair isn’t available, a similar quantity of body hair can be used. Head hair specifically refers to hair from the scalp, whereas body hair encompasses all other hair kinds (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result primarily involves these four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about the initial integration of a sample into the lab's infrastructure. It includes confirming that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and doing any additional data entry not available via an electronic chain of custody system.

Screening comprises an initial rapid assessment for drugs of abuse. Although Screening is an economical method for eliminating drug consumption in most cases, a favorable screening result requires validation for legal proceedings. Any samples initially flagged positive in Screening demand secondary substantiation.

In cases of a tentative positive result from Screening, more hair is obtained from the original specimen for Extraction. During this phase, substances are extracted from hair at lower concentrations compared to other techniques (e.g., urine or oral fluid), rendering hair drug screening as the most complex to execute.

A confirmed positive screen is validated using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples preliminarily marked positive are cleansed before confirmation as necessary. The entire laboratory sequence from Accessioning to Verification is conducted under the CAP (College of American Pathologists) Hair designation and upholds ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage over 90 days, unlike urine tests which cover a shorter period.
• Difficult to manipulate: Cheating a hair drug test is highly challenging, enhancing result accuracy.
• Offers historical insight: It showcases a drug use pattern over a certain duration, rather than just recent activity.

Limitations:

• No detection of recent usage: Drugs typically take around 5-7 days to become noticeable in hair.
• Expense: Hair drug tests are usually costlier compared to alternative drug testing approaches.
• Result variability: Variables such as hair shade and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Often termed as "hair follicle tests", the actual test evaluates the hair strand itself and not the follicle below the scalp
