Hair Follicle Drug Testing - Holmen, WI

What it is, How it works

As a compelling approach for identifying drug and alcohol consumption, hair testing offers valuable insights. Hair captures long-term drug and alcohol biomarkers within the hair strand's fibers as it grows. When obtained near the scalp, a hair sample allows for up to roughly a 3-month detection dimension for various drugs, including alcohol. Hair is straightforward to gather, somewhat resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, approximately 200 hair strands (roughly the thickness of a #2 pencil), closest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmation. For tests such as EtG, add-ons, or panels surpassing 10, a 150mg sample is advisable. It's suggested to weigh the sample using a jeweler's scale. If scalp hair isn't available, a similar quantity of body hair may be utilized. When head hair is specified, it signifies exclusively scalp hair. Body hair includes all other kinds (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes initial processing within the lab's system. This entails confirming the sample's proper sealing and shipment, assigning a randomized LAN (Laboratory Accessioning Number), and filling any additional data not provided through an electronic chain of custody.

Screening is a preliminary, rapid assessment for drugs of abuse. While cost-effective for ruling out drug use in most samples, any positive screenings require confirmation to be considered legally valid. Samples testing presumptively positive in the Screening must undergo a follow-up confirmation.

For samples with a presumptively positive result during Screening, more hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from the hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to perform.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are cleansed before confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is monitored under both CAP (College of American Pathologists) Hair protocols and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a span of up to 90 days, unlike urine tests that offer a shorter detection period.
• Challenging to falsify: Hair drug tests are extremely difficult to manipulate, ensuring greater accuracy in results.
• Offers usage pattern history: It reveals patterns of drug use over time, not merely recent usage.

Limitations:

• Not suitable for recent drug use detection: It requires around 5-7 days before drugs become detectable in hair.
• Expense: Typically, hair drug tests are more costly compared to other drug testing methods.
• Result variations: Factors like hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: Despite being termed "hair follicle tests," the analysis targets the hair strand rather than the follicle beneath the scalp.
