Hair Follicle Drug Testing - Dexter, MN

What it is, How it works

Hair tests have become essential for detecting alcohol and drug usage. Hair offers an extended history of substances due to biomarkers getting embedded in the hair strand as it grows. When sourced close to the scalp, it can reveal drug and alcohol use for roughly a 3-month window. It’s easy to obtain, relatively resistant to tampering, and straightforward to transport.

A 1.5-inch section consisting of approximately 200 strands of hair (around the thickness of a #2 pencil) near the scalp yields 100mg of hair, deemed perfect for screening and confirmation processes. For EtG, additional tests, and/or panels beyond 10, it's advisable to use 150mg of hair. We suggest measuring the sample with a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair may be used. When referring to head hair, we indicate scalp hair exclusively. Body hair pertains to all other hair types (facial, axillary, etc.).

Process Overview

The primary stages in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with integrating the sample into a lab's system. This process ensures the sample was securely sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and completes additional data entry absent from an electronic chain of custody system.

Screening conducts a preliminary check for substance abuse. Although Screening offers a cost-efficient method to negate drug use in most samples, a positive result after screening necessitates validation to be legally admissible. Samples with suspected positive results in Screening demand a secondary confirmation.

Should a sample show a positive indication in the Screening phase, extra hair is extracted from the submitted specimen and readied for Extraction. Here, substances are extracted from hair at a notably reduced concentration compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation for any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with a presumptive positive are washed as needed. The entire lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug screenings can trace drug consumption up to 90 days, unlike urine tests, which have a more limited detection period.
• Challenging to falsify: It's notably hard to deceive a hair drug test, thus enhancing result accuracy.
• Historical insights: It can illustrate a pattern of drug consumption over a duration, rather than just recent use.

Limitations:

• Incapacity to detect recent consumption: Approximately 5-7 days are required for drugs to become perceptible in hair.
• Expense: Hair drug screenings typically incur higher costs than alternative testing techniques.
• Result variability: Elements such as hair hue and personal growth differences can influence drug metabolite concentrations within hair.

Note: Frequently labeled as "hair follicle tests", the test focuses on analyzing the hair strand rather than the hair follicle beneath the scalp.
