Hair Follicle Drug Testing - Souderton, PA

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, providing an extended history of substance use. When collected near the scalp, hair offers a detection period of up to about 3 months for alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (approximately the size of a #2 pencil) near the scalp yields 100mg of hair, an optimal sample size for screening and confirmation. For EtG, additional screenings, and/or tests exceeding 10 panels, a specimen of 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair cannot be collected, an equivalent amount of body hair may be used. The term head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial step of entering a sample into a lab’s system. This process includes ensuring the sample was sealed and transported correctly, issuing a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry if not provided by an electronic chain of custody system.

Screening offers a preliminary check for drug abuse. While Screening is a cost-efficient way to exclude drug usage in most samples, a positive screen must be verified to be legally admissible. Samples that show a presumptive positive during Screening require further confirmation.

In cases of presumptive positive results from Screening, additional hair is collected from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.

Any positive screening result goes through Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed if necessary before confirmation. The lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, compared to urine tests which have a shorter detection window.
• Difficulty to cheat: It is very difficult to cheat a hair drug test, making the results more accurate.
• Provides historical data: It can provide a pattern of drug use over a period of time, not just recent use.

Limitations:

• Cannot detect recent use: It takes approximately 5-7 days for drugs to be detectable in hair.
• Cost: Hair drug tests are generally more expensive than other drug testing methods.
• Variations in results: Factors such as hair color and individual variations in hair growth can affect the concentration of drug metabolites in the hair.

Note: Although commonly referred to as "hair follicle tests," the test analyzes the hair strand rather than the hair follicle below the scalp.
