Hair Follicle Drug Testing - Princeton, NE

What it is, How it works

Hair analysis has become recognized as an effective means for identifying drug and alcohol consumption. Hair serves as a chronic snapshot of substance use by encasing biomarkers within the strands of a developing hair piece. When taken close to the scalp, hair can reveal up to around a 3-month lookback period for substances like alcohol and other drugs. Gathering hair is uncomplicated, relatively tamper-proof, and simple to transport.

A hair sample measuring 1.5 inches with roughly 200 strands (equivalent to the girth of a #2 pencil) from the scalp offers 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg of the specimen is suggested. It's advisable to weigh this on a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair may be used. When we reference head hair, we're specifically talking about scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The drug test laboratory process consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the procedure of initially entering a sample into a lab's system. This step verifies that the sample was properly sealed and mailed, allocates a random LAN (Laboratory Accessioning Number), and finalizes any incomplete data entry not handled by the electronic chain of custody system.

Screening is a preliminary expedited review to identify drug abuse. While Screening is cost-efficient in excluding drug usage in most samples, any positive outcomes need to be confirmed for legal acceptability. Samples registering presumptive positives during Screening require subsequent confirmation.

If a sample is tentatively positive during Screening, additional hair is derived from the original specimen and readied for Extraction. During this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), marking hair testing as the most challenging methodology.

Any positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive undergo washing prior to confirmation as necessary. The comprehensive lab procedure, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair credentials and complies with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can ascertain drug consumption over a 90-day span, unlike urine tests with shorter periods.
• Hard to manipulate: Manipulating the outcome of a hair drug test is very challenging, enhancing result accuracy.
• Chronological data: They provide a historical analysis of substance usage, rather than just recent activity.

Limitations:

• Incapable of detecting recent consumption: Drugs typically become noticeable in hair 5-7 days post-use.
• Expense: Hair drug tests generally cost more than alternative testing methods.
• Result variability: Elements like hair color and personal growth differences can impact drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests," the focus is on analyzing the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair testing offers several advantages over urine testing in Princeton, NE, primarily due to its higher detection accuracy and reliability.
