Hair Follicle Drug Testing - Reserve, WI

What it is, How it works

Seen as efficient, hair testing serves as a valuable means to identify drug and alcohol consumption. By preserving biomarkers within the structure of the growing hair, it provides a comprehensive history of substance use. When retrieved near the scalp, it can reveal drug and alcohol use history for a period of roughly three months. Hair samples are easy to collect, challenging to tamper with, and conveniently shipped.

A 1.5-inch segment containing approximately 200 hair strands (resembling the width of a #2 pencil) next to the scalp provides 100mg of hair, considered an optimal sample for both screening and validation. For extended tests, such as EtG, additional analyses, and tests exceeding ten panels, 150mg of the sample is advisable. It is suggested to use a jeweler's scale for specimen measurement. In the absence of scalp hair, a comparable volume of body hair might be taken. 'Head hair' denotes scalp hair exclusively, while 'body hair' includes all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis for drug testing involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where samples are processed into the laboratory's system. This comprises confirming proper sealing and shipment of the sample, assigning it a LAN (Laboratory Accessioning Number) randomly, and finishing any remaining data entry not completed via an electronic chain of custody system.

The Screening phase consists of a preliminary fast check for substance abuse. Although it's an economical approach to eliminate drug use in many samples, court-admissible evidence necessitates confirming any positive screen. Any samples that test potentially positive during Screening necessitate additional confirmation.

If Screening indicates a possibly positive outcome, additional hair is extracted from the original sample and readied for Extraction. In Extraction, drugs are retrieved at significantly lower concentrations from hair compared to other methods (like urine or oral fluid), hence making hair drug testing one of the most complex methods to conduct.

Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before Confirming, all samples deemed presumptively positive are cleansed as needed. The entire laboratory procedure from Accessioning through Confirmation is assessed both under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage spanning up to 90 days, unlike urine tests offering a comparatively limited detection timeline.
• Challenging to manipulate: Cheating a hair drug test is quite difficult, ensuring more reliable outcomes.
• Offers historical insights: Helps in understanding patterns of drug consumption over time, beyond just recent use.

Limitations:

• Inability to determine recent consumption: Drugs become traceable in hair roughly 5-7 days post-use.
• Expense: Typically, hair drug testing incurs a greater cost as compared to alternative drug-testing approaches.
• Result variability: Elements such as hair color and individual hair growth differences may influence metabolite concentration levels in hair.

Note: Although commonly referred to as "hair follicle tests," it is the hair strand that undergoes analysis, not the follicle beneath the scalp.
