Hair Follicle Drug Testing - Northcote, MN

What it is, How it works

Hair testing is increasingly viewed as an effective method for detecting alcohol and drug usage. Hair can reveal an extended timeline of alcohol and other drugs by embedding biomarkers in the fibers of the hair as it grows. When hair is gathered near the scalp, it offers up to about a 3-month window for detecting alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and easy to transport.

A 1.5-inch cut of roughly 200 hair strands (comparable to the diameter of a #2 pencil) from the scalp will yield 100mg of hair, which is the preferred sample size for screening and confirmation purposes. For EtG, add-ons, and/or testing exceeding 10 panels, 150mg of the sample is advisable. It is suggested to use a jeweler's scale for weighing the sample. If scalp hair is not an option, a similar amount of body hair can be collected. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial phase of integrating a sample into a laboratory's system. This step checks that the sample was sealed and transported correctly, a random LAN (Laboratory Accessioning Number) is assigned, and any further data entry not covered by an electronic chain of custody system is completed.

Screening refers to a preliminary check for drugs of abuse. Although Screening is a cost-efficient means to eliminate drug usage in most samples, a positive result in Screening necessitates confirmation for court acceptance. Samples with a presumptive positive in Screening require an additional confirmation.

Should a sample test as presumptive positive at the Screening stage, more hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at a lower concentration than other techniques (such as urine or oral fluid), which is why hair drug screening is the most sophisticated method to undertake.

Confirmation of any screening positive is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as needed. Both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards oversee the entire laboratory process from Accessioning to Confirmation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for approximately 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: Deceiving a hair drug test is exceedingly difficult, resulting in more precise results.
• Provides historical usage data: It can chart a pattern of drug use over time, beyond just recent consumption.

Limitations:

• Cannot identify recent usage: It typically takes 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are typically pricier than alternative drug testing methods.
• Result variability: Variables such as hair color and individual disparities in hair growth can impact drug metabolite concentration in the hair.

Note: Although often termed as "hair follicle tests", the test actually analyzes the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Northcote, MN, hair follicle testing is gaining traction over traditional urine tests. The method’s benefits include superior detection accuracy and increased reliability for assessing substance use.
