Hair Follicle Drug Testing - Woodland, WI

What it is, How it works

The utilization of hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair offers a long-standing record of alcohol and other drugs by incorporating biomarkers within the strands of growing hair. When gathered near the scalp, hair can offer a detection period of up to approximately three months for alcohol and other substances. Collecting hair is straightforward, relatively challenging to tamper with, and simple to dispatch.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (equivalent to the diameter of a #2 pencil) closest to the scalp will yield 100mg, which is the optimal amount for both screening and verification. For EtG, additional tests, and/or analyses extending beyond 10 panels, a 150mg sample is suggested. It's advisable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. When referring to head hair, we mean scalp hair specifically. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result primarily encompasses four phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary handling of a sample within a laboratory’s system. This stage involves confirming the sample was sealed and dispatched correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody system.

Screening is a preliminary, expedited assessment for substances of abuse. While Screening is an economical approach to dismiss drug use in a majority of samples, any positive results necessitate confirmation for court admissibility. Samples showing presumptive positive results in Screening require further confirmation.

Should a sample show presumptive positivity during the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. Here, substances are derived from hair at concentrations notably lower than those found in other methods (e.g., urine or oral fluid), which is why hair drug screening poses the most complex methodology.

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

Advantages of hair drug testing:

• Prolonged detection period: Hair drug analyses can identify drug use up to 90 days, as opposed to urine tests with shorter detection spans.
• Resistance to manipulation: It is exceedingly difficult to falsify a hair drug test, thus enhancing result accuracy.
• Provides chronological data: Can display a pattern of substance use over time, not just current use.

Limitations:

• Inability to detect recent consumption: Drugs only become traceable in hair after approximately 5-7 days.
• Expense: Hair drug analyses generally incur higher costs than other testing methods.
• Resulting variations: Differing factors like hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly referred to as "hair follicle tests," the analysis targets the hair strand itself rather than the follicle beneath the scalp.
