Hair Follicle Drug Testing - Danville, IA

What it is, How it works

Hair testing has emerged as an effective method for detecting drug and alcohol usage. Hair offers a comprehensive history of alcohol and drugs by capturing biomarkers within its fibers as it grows. By collecting hair near the scalp, it can reveal substance use for a detection window of roughly 3 months for alcohol and drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and easy to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil) nearest the scalp yields 100mg, the optimal amount for both screening and confirmation. For tests involving EtG, add-ons, and/or those exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair cannot be sourced, an equivalent quantity of body hair may be gathered. Reference to head hair exclusively denotes scalp hair, while body hair encompasses all other types (like facial, axillary, etc.).

Process Overview

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

Accessioning marks the initial processing of a sample into a laboratory’s system. This step ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not covered by an electronic chain of custody system.

Screening entails a preliminary rapid check for substances of abuse. While Screening provides a cost-effective means to eliminate drug use in most samples, a positive result must be confirmed to hold up in court. Any samples suspected to be positive in Screening necessitate a follow-up confirmation.

Samples that appear positive during the Screening phase undergo further preparation in Extraction by pulling more hair from the initial sample. In this stage, drugs are extracted from hair at lower concentrations than in other methods (such as urine or oral fluid), highlighting why hair drug screening is considered the most complex methodology.

Confirmation of any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation as well as accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, in contrast to urine tests which have a shorter detection duration.
• Challenging to deceive: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Historical data provision: It shows a pattern of drug use over time, not limited to recent activity.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for drugs to be detected in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Result variability: Variations like hair color and individual differences in hair growth may impact drug metabolite concentration in hair.

Note: Frequently termed "hair follicle tests", the procedure evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Danville, IA, hair testing emerges superior when juxtaposed with urine testing. Hair follicle assessments bring enhanced reliability due to their expanded detection period and their reduced tampering susceptibility.
