Hair Follicle Drug Testing - Dominion, MD

What it is, How it works

Hair testing has emerged as an effective means for detecting drug and alcohol consumption. Hair captures a long-term record of drugs and alcohol by encasing biomarkers within the fibers of the growing strand. When taken near the scalp, hair can reveal up to a three-month detection window for alcohol and other substances. Collecting hair is straightforward, not easily tampered with, and conveniently shipped.

A specimen of 1.5 inches or approximately 200 hair strands (about the size of a #2 pencil) closest to the scalp yields 100mg, which is the optimal sample size for screening and confirmation. For tests involving EtG, additional analysis, or those exceeding 10 panels, a 150mg sample is suggested. We recommend weighing the specimen using a jeweler’s scale. If scalp hair is unobtainable, an equivalent amount of body hair can be used. When discussing head hair, this specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary steps in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially entering a sample into the laboratory's system. This step includes confirming that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.

Screening provides an initial, rapid assessment for drugs of abuse. It serves as a cost-effective method to eliminate drug use in most samples, but a positive screen requires confirmation to be valid in legal proceedings. Any tentative positives in Screening require further confirmation.

If a sample appears positive in Screening, additional hair is extracted from the initial sample for Extraction. This phase isolates drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), thus making hair drug testing the most challenging method to execute.

Confirmation of any positive results from screening is performed using GC/MS, GC/MS/MS or LC/MS/MS techniques. All tentatively positive samples are cleansed prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, versus urine tests which have a more limited detection timeframe.
• Challenging to manipulate: Fabricating results from a hair drug test is extremely difficult, enhancing accuracy.
• Tracks historical usage: It can reveal a usage trend over time, rather than just recent consumption.

Limitations:

• Incapable of detecting recent use: It typically takes 5-7 days before drugs become detectable in hair.
• Expenses: Hair drug tests frequently cost more than other testing methods.
• Result variations: Differences such as hair color and personal hair growth rates can impact metabolite levels in hair.

Note: While commonly called "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
