Hair Follicle Drug Testing - Greenway, AR

What it is, How it works

Hair testing is now recognized as a significant method for identifying drug and alcohol consumption. Hair encapsulates a comprehensive record of alcohol and drugs by embedding biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair can offer a detection window of up to about 3 months for alcohol and other drugs. Collecting hair is straightforward, not easy to tamper with, and convenient to transport.

A 1.5-inch portion of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal amount for screening and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, a 150mg specimen is suggested. We advocate for measuring the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be collected. When mentioning head hair, we mean scalp hair exclusively. Body hair includes all other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning involves the primary processing of a specimen into a laboratory’s system. This encompasses confirming the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry lacking from an electronic chain of custody process.

Screening involves an initial rapid assessment for illicit substances. Screening is a cost-efficient strategy to exclude drug use in most samples; however, a positive screen must be authenticated to be valid in legal proceedings. Samples that are presumptively positive in Screening demand a secondary confirmation.

In cases where a sample is presumptively positive at the Screening phase, additional hair is gathered from the primary specimen and readied for Extraction. During this phase, substances are extracted from the hair at much lower concentrations compared to other methods (e.g. urine or oral fluid), which makes hair drug testing the most challenging procedure to conduct.

Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation, as necessary. The entire laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use for up to 90 days, whereas urine tests have a shorter detection period.
• Difficult to falsify: Cheating on a hair drug test is extremely challenging, thus enhancing result accuracy.
• Offers historical insights: It can depict a pattern of drug use over time, not merely recent usage.

Limitations:

• No detection of recent use: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Variability in results: Elements such as hair color and individual differences in hair growth can impact the levels of drug metabolites in hair.

Note: Despite common reference to "hair follicle tests," the test examines the hair strand, not the follicle beneath the scalp.
