Hair Follicle Drug Testing - Fox Run, PA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying substance use. By capturing biomarkers in the fibers of a growing hair strand, hair offers an extended history of drug and alcohol consumption. When obtained near the scalp, hair enables a detection timeframe of up to roughly 90 days for substances. Hair collection is straightforward, difficult to tamper with, and easy to transport.

A sample of 1.5 inches containing around 200 hairs (approximately the diameter of a #2 pencil) from near the scalp yields 100mg, ideal for screening and confirmation. For EtG, extra tests, or panels above 10, 150mg is suggested. It’s advisable to weigh the sample using a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair can be gathered. "Head hair" specifically refers to scalp hair, while "body hair" includes other types (facial, underarm, etc.).

Process Overview

The lab procedure for drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into the lab's system, which includes verifying proper sealing and dispatch, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any extra data entry not covered by an electronic chain of custody.

Screening provides an initial, swift assessment for drug misuse. Though cost-efficient for excluding drug use in most samples, a positive screen requires confirmation for court admissibility. Samples that test positive in Screening must undergo further verification.

For samples presumed positive in the Screening stage, additional hair is extracted and readied for Extraction. Drugs are removed from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.

Confirmation of positive screening outcomes is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Positive samples are cleaned before confirmation if needed. The lab process from Accessioning to Confirmation is reviewed under CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assays can reveal drug use for up to 90 days, whereas urine tests have a shorter timeframe.
• Hard to falsify: Cheating a hair drug test is notably difficult, thus enhancing result accuracy.
• Historical data: It offers a timeline of drug consumption over time, unlike recent use detection alone.

Limitations:

• No recent use detection: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug testing is generally costlier than other drug screening methods.
• Results variability: Elements like hair color and growth variability can impact metabolite concentrations in hair.

Note: While sometimes called "hair follicle tests", the analysis actually focuses on the hair strand, not the follicle beneath the scalp.
