Hair Follicle Drug Testing - Independence, MO

What it is, How it works

Hair analysis has grown to be recognized as an effective method for detecting alcohol and drug use. Hair maintains a prolonged record of alcohol and drug intake by capturing biomarkers within the elongating hair fibers. When obtained near the scalp, hair can furnish an approximate 3-month detection period for substances. Hair sampling is straightforward, difficult to tamper with, and convenient to transport.

A 1.5-inch segment, containing about 200 hair strands (roughly equivalent to the diameter of a #2 pencil) positioned nearest the scalp, will yield 100mg of hair, which is the optimal amount for testing and validation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale is recommended for weighing the specimen. In cases where scalp hair is not available, a proportional amount of body hair may be obtained. Head hair pertains specifically to scalp hair, whereas body hair encompasses other types (face, armpits, etc.).

Process Overview

The primary steps in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into a lab's framework. This stage involves confirming the sample's secure sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any residual data entry absent from an electronic documentation system.

Screening comprises an initial evaluation for common drugs. Though Screening is a cost-effective method for excluding drug usage in most samples, a positive result requires confirmation to be court-admissible. Samples with presumptive positives during Screening will necessitate further verification.

In instances where a sample shows a presumptive positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are removed from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.

The Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing prior to Confirmation as necessary. The entire procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use up to 90 days, whereas urine tests have a more limited detection period.
• Hard to tamper with: It is exceptionally challenging to deceive a hair drug test, thereby enhancing the accuracy of results.
• Offers past usage patterns: It provides an array of drug use over time, beyond just recent consumption.

Limitations:

• Cannot identify recent use: Drugs take roughly 5-7 days to be present in hair.
• Expense: Hair drug tests are typically costlier than alternate drug testing solutions.
• Result variability: Aspects like hair color and individual hair growth rates can influence the concentration of drug metabolites in hair.

Note: Frequently labeled as "hair follicle tests," this test evaluates the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
