Hair Follicle Drug Testing - Fostoria, IA

What it is, How it works

Hair testing is now regarded as an efficient method for detecting drug and alcohol consumption. By capturing biomarkers within the fibers of growing hair strands, hair serves as a long-term indicator of alcohol and drug use. When samples are taken close to the scalp, hair has the ability to reveal a detection timeframe of around three months for alcohol and drugs. Collection of hair is straightforward, is not easily tampered with, and is convenient to transport.

For optimal screening and confirmation, a 1.5-inch section of roughly 200 hair strands—comparable in size to a #2 pencil—nearest to the scalp yields 100mg, the ideal sample weight. For EtG tests, additional panels, or tests exceeding 10 panels, a collection of 150mg is advisable. Utilizing a jeweler’s scale is recommended for weighing the sample. Should scalp hair be unavailable, an equivalent quantity of body hair may suffice. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other types, such as facial and axillary hairs.

Process Overview

The process of laboratory drug test analysis includes these four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of integrating a sample into the laboratory's framework. This involves ensuring the sample is properly sealed and sent, assigning it a random LAN (Laboratory Accessioning Number), and completing any remaining data entry tasks not already handled by an electronic custody chain system.

Screening offers an initial assessment for potential drug misuse. It is a cost-efficient method to exclude drug usage in most instances; however, any positive screening results must be confirmed for court admissibility. Samples showing a presumptive positive in Screening require additional validation.

For samples testing presumptive positive during the Screening phase, more hair is extracted from the initial sample for the Extraction process. In this phase, drug concentrations are extracted from hair at a lower level compared to other techniques like urine or oral fluid testing, rendering hair drug screening one of the most challenging methodologies.

Confirmation of positive screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to Confirmation, all presumptive positive samples are washed as needed. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can uncover drug use over a 90-day period, as opposed to urine tests with shorter detection spans.
• Difficulty to cheat: The difficulty in manipulating hair drug tests ensures more reliable outcomes.
• Provides historical data: Offers a timeline of drug consumption patterns, not solely limited to recent usage.

Limitations:

• Cannot detect recent use: Drugs become discernible in hair only after approximately 5-7 days.
• Cost: Generally, hair drug tests entail higher costs compared to alternative drug testing methods.
• Variations in results: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", these tests analyze the hair strand rather than the follicle beneath the scalp.
