Hair Follicle Drug Testing - Dent, MN

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands as it grows, providing a lengthy history of substance use. When taken near the scalp, hair offers a detection period of up to roughly three months for alcohol and other drugs. It is easy to collect, resistant to tampering, and simple to transport.

A 1.5-inch piece consisting of around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair can be used. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The primary stages involved in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves introducing a sample into the lab's system, which includes validating that it was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and performing any required data entry not covered by an electronic chain of custody system.

Screening entails an initial rapid check for drugs of abuse. While Screening is a cost-efficient approach to exclude drug use in most samples, a positive result must be confirmed to be legally valid. Presumptive positive results in Screening necessitate a secondary confirmation.

If the sample tests positive during the Screening phase, additional hair is extracted from the original sample for the Extraction process. In Extraction, drugs are isolated from hair at a significantly lower concentration than in other methods (such as urine or oral fluid), which makes hair drug testing a challenging procedure.

GC/MS, GC/MS/MS, or LC/MS/MS is used to validate any positive result from Screening. Presumptive positive samples are cleansed before confirmation when necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and follows the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, as opposed to urine tests with a narrower detection span.
• Challenging to manipulate: Cheating on a hair drug test is exceptionally difficult, enhancing result accuracy.
• Historical use data: It can outline a pattern of drug use over time, rather than merely recent consumption.

Limitations:

• Incapable of detecting recent usage: Drugs take approximately 5-7 days post-consumption to become detectable in hair.
• Expense: Hair drug tests are typically pricier compared to other drug testing methodologies.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in the hair.

Note: Although often termed "hair follicle tests", the analysis is performed on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Dent, MN, hair follicle testing outperforms traditional urine tests by providing superior accuracy and reliability.
