Hair Follicle Drug Testing - Lake Havasu City, AZ

What it is, How it works

Hair testing is now recognized as an influential method for detecting drug and alcohol consumption. It provides a prolonged history of these substances by ensnaring biomarkers within the fibers of the growing hair. When sampled near the scalp, it offers a detection span of up to three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A sample measuring 1.5 inches containing around 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp yields approximately 100mg of hair, suitable for both screening and verification. For EtG, supplementary tests, and analysis over 10 panels, 150mg of the specimen is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. "Head hair" denotes scalp hair exclusively, whereas "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary integration of a sample into a lab's system. This step checks if the sample was appropriately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and covers any further data entry absent from an electronic chain of custody system.

Screening carries out an initial rapid assessment for drug abuse signs. Although Screening is a cost-efficient means to discount drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Samples that test presumptively positive in Screening require additional confirmation.

When a sample tests presumptively positive during Screening, more hair is extracted from the initial sample and prepared for Extraction. Drugs are extracted from hair at notably lower concentrations than with other methods (such as urine or oral fluid), making hair drug screening the most complex methodology.

Confirmation of any positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation as required. The lab process from Accessioning to Confirmation is governed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a span of up to 90 days, while urine tests are limited to a shorter detection duration.
• Challenging to falsify: Manipulating a hair drug test is extremely difficult, thus enhancing result accuracy.
• Offers historical insights: It provides a usage pattern over time rather than mere recent use.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically costlier than other testing approaches.
• Result variability: Variables like hair color and personal differences in hair growth impact the concentration of drug metabolites in hair.

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

Why Hair Follicle Testing Beats Urine Testing
