Hair Follicle Drug Testing - Waconia, MN

What it is, How it works

Hair testing has emerged as a significant method for identifying drug and alcohol use. Hair offers an extended history of alcohol and drug consumption by capturing biomarkers within the fiber of the hair strand as it grows. When collected near the scalp, hair provides a detection period of up to three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch hair sample consisting of approximately 200 strands (about the thickness of a #2 pencil) taken nearest the scalp will yield 100mg, the optimal amount for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advised. Measuring the hair sample using a jeweler’s scale is recommended. In the absence of scalp hair, an equivalent quantity of body hair can be used. "Head hair" refers solely to scalp hair, whereas "body hair" encompasses other hair types (facial, axillary, etc.).

Process Overview

The principal steps in lab processing of drug test samples include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of inputting a sample into a laboratory system. It involves ensuring the sample was sealed and dispatched correctly, generating a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry that's not part of an electronic chain of custody system.

Screening involves a quick initial review for drugs of abuse. Screening serves as an economical way to eliminate drug use in most samples, but a positive result must be confirmed for court admissibility. Any samples that screen positively require further confirmation.

If a sample yields a presumptive positive result during Screening, more hair is gathered from the original sample for Extraction. During this phase, drugs are retrieved from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening among the most challenging techniques to conduct.

Positive screening results are confirmed using GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, presumptive positive samples are washed as necessary. The entire laboratory processing from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests, which have a shorter detection timeframe.
• Hard to alter results: Cheating a hair drug test is highly challenging, resulting in more reliable outcomes.
• Tracks usage history: It offers a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug testing generally costs more than alternative drug testing methods.
• Result variability: Hair color and personal disparities in hair growth can influence drug metabolite concentration in hair.

Note: Although often referred to as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing holds several advantages over traditional urine tests, especially in Waconia, MN. Firstly, the detection window is significantly longer, allowing for a 90-day review of substance use.
