Hair Follicle Drug Testing - Dundee, MN

What it is, How it works

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair strands capture a long-term record of alcohol and drug use by containing biomarkers within the hair's growing fibers. When gathered near the scalp, hair can provide a detection timeframe of up to about three months for alcohol and drugs. The collection process is straightforward, with minimal risk of tampering, and the samples are easy to transport.

A hair specimen of 1.5 inches, around 200 strands (approximately the thickness of a #2 pencil), nearest to the scalp supplies 100mg of hair—ideal for both initial screening and verification tests. For tests such as EtG, additional screenings, or panels exceeding 10, a sample of 150mg is suggested. Accurate specimen weighing can be done using a jeweler's scale. If scalp hair is not accessible, an equivalent quantity of body hair can be used. By head hair, we mean only scalp hair; body hair pertains to all other types (e.g., facial, axillary).

Process Overview

The laboratory procedures for processing a drug test result consist of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into the laboratory's system, including ensuring the proper sealing and shipping of the sample, random LAN (Laboratory Accessioning Number) assignment, and finalizing any necessary data entry not covered by the electronic chain of custody.

Screening is a preliminary check for drugs of abuse. Though cost-effective for excluding drug usage in many samples, a positive result from Screening necessitates further confirmation for legal admissibility. Presumptive positives from Screening must undergo an additional confirmation step.

When Screening indicates a presumptive positive, more hair is utilized from the initial sample and prepared for Extraction. In this phase, drugs are separated from hair at a concentration much lower compared to methods like urine or oral fluid, highlighting hair drug screening’s complexity.

Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleaned as needed before confirmation. From Accessioning to Confirmation, the lab procedures are overseen by the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests reveal drug usage up to 90 days, whereas urine tests have a limited detection period.
• High resistance to tampering: Cheating a hair drug test is notably challenging, thus ensuring more reliable results.
• Historical usage pattern: It shows patterns of drug use over time, rather than just recent usage.

Limitations:

• Ineffective for recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing methods.
• Potential result variability: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", these tests analyze the hair shaft itself and not the follicles beneath the scalp.
