Hair Follicle Drug Testing - Centennial Park, AZ

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged historical record of drugs and alcohol by capturing biomarkers within the fibers of the hair as it grows. Collected near the scalp, hair can reveal substance use within an approximate three-month period. It is straightforward to collect, relatively resistant to tampering, and simple to transport.

A sample of 1.5 inches, consisting of roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp, equates to 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG and additional tests exceeding 10 panels, a specimen size of 150mg is advised. Using a jeweler's scale to weigh the sample is recommended. If scalp hair is not available, the same amount of body hair may be utilized. The term head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial processing of a sample within a laboratory's framework. This step involves checking that the sample was sealed and shipped correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry not included via an electronic chain of custody system.

Screening is a preliminary check for drugs of abuse. It is an economical way to eliminate drug usage in most samples; however, a positive Screen must be validated for court admissibility. Samples that test presumptively positive in Screening require subsequent confirmation.

In the event of a presumptively positive result in the Screening phase, additional hair is taken from the original specimen for Extraction. At this stage, drugs are extracted at a much lower concentration compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening as a methodology.

GC/MS, GC/MS/MS, or LC/MS/MS are utilized for the Confirmation of any positive Screening results. All samples that test presumptively positive are cleansed prior to Confirmation if required. The entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests are capable of identifying drug usage for up to 90 days, unlike urine tests that offer a shorter detection duration.
• Hard to manipulate: Cheating a hair drug test is quite challenging, thereby enhancing accuracy.
• Provides usage patterns: It reveals a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Cannot detect immediate use: It requires about 5-7 days before drugs become traceable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variability: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

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

Why Hair Follicle Testing Beats Urine Testing

In Centennial Park, AZ, hair follicle testing surpasses traditional urine tests by offering superior detection accuracy and reliability. Hair tests can detect drug use over a much longer period, up to 90 days, allowing for a comprehensive understanding of an individual's substance use history.
