Hair Follicle Drug Testing - Lincoln, NE

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. By encasing biomarkers within the hair fibers as they grow, hair offers a comprehensive record of substance use over time. When samples are taken from near the scalp, it can reveal drug and alcohol activity over a span of up to three months. Collecting hair is straightforward, alteration is relatively challenging, and transportation is uncomplicated.

A sample measuring 1.5 inches consisting of around 200 hair strands (equivalent to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for screening and confirmatory analysis. For enhanced tests like EtG, or panels above ten, a 150mg specimen is advisable. It's suggested to use a jeweler's scale for precise weighing of the specimen. Should scalp hair be absent, a similar quantity of body hair can be used. Scalp hair specifically denotes head hair, while body hair pertains to all other hair types (including facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result encompasses four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails incorporating the sample into a laboratory's framework. This step ensures the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data input absent from an electronic chain of custody system.

Screening provides an initial scan for drugs of interest. While it offers a cost-efficient solution to rule out drug presence in most samples, confirmation is necessary for legal viability in cases of positive results. Presumptive positive samples in Screening require subsequent validation.

Upon a presumptive positive result during Screening, additional hair is extracted from the primary specimen for the Extraction phase. In this phase, drugs are drawn from the hair at much lower levels than alternative methods (e.g., urine or saliva), which explains the complexity of conducting hair drug analysis.

Verification of any presumptive positive results occurs using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo a cleansing process prior to confirmation as required. The entire process, spanning from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) guidelines for Hair and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing identifies substance use for up to 90 days, unlike urine testing with its shorter detection range.
• Resistance to tampering: Hair drug testing is notably difficult to manipulate, enhancing result reliability.
• Historical consumption patterns: It reveals a pattern of drug consumption over time instead of merely recent use.

Limitations:

• Inability to detect recent consumption: Drugs only become noticeable in hair approximately 5-7 days post-consumption.
• Higher expense: Generally, hair drug testing costs more than alternative methods.
• Result variability: Attributes like hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Commonly known as "hair follicle tests", the analysis targets the hair strand rather than the underlying scalp follicle.
