Hair Follicle Drug Testing - West Newton, PA

What it is, How it works

Hair testing is now acknowledged as an effective method for detecting drug and alcohol consumption. It captures a comprehensive history of these substances by embedding biomarkers in the fibers of hair as it grows. When gathered near the scalp, hair can provide an insight into a user’s drug and alcohol history for nearly a 3-month period. The method of collecting hair is straightforward, relatively resistant to tampering, and simple to transport.

Obtaining a 1.5-inch sample that includes around 200 strands (equivalent to the thickness of a #2 pencil) from the scalp is optimal, yielding 100mg of hair needed for preliminary and confirmatory testing. For assessments like EtG, additional tests, or tests exceeding 10 panels, a 150mg specimen is advisable. It’s suggested to weigh the collected hair using a jeweler’s scale. If scalp hair is not available, an identical quantity of body hair may be substituted. Our reference to head hair signifies only scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

There are four primary stages in a lab’s drug test result processing: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is firstly entered into a laboratory’s system. This phase includes ensuring the sample was correctly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and inputting any supplementary data absent from an electronic chain of custody.

Screening offers an initial examination for signs of drug abuse. While it is an economical method to exclude drug usage for most samples, a positive screen must be verified to hold up in court. Samples indicating a presumptive positive during Screening necessitate subsequent confirmation.

For samples marked presumptively positive in the Screening phase, additional hair is taken from the initial sample to prepare for Extraction. This stage involves extracting drugs from the hair at lower concentrations than those in other methodologies (example: urine or oral fluids), reinforcing hair drug screening's complexity.

Any positive screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples presumed positive undergo necessary washing before confirmation. The comprehensive laboratory process, from Accessioning to Confirmation, is inspected following the CAP (College of American Pathologists) guidelines for Hair and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can uncover drug use spanning up to 90 days, unlike urine tests with a reduced detection period.
• Challenging to manipulate: The difficulty in tampering with a hair drug test enhances result reliability.
• Offers historical insights: Provides a timeline of drug usage over time rather than just recent consumption.

Limitations:

• Incapable of detecting recent usage: It generally takes 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are typically more costly compared to others.
• Result variability: Aspects such as hair pigment and individual growth differences can influence drug metabolite concentration in hair.

Note: Although often termed as "hair follicle tests", these tests examine the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In West Newton, PA, hair follicle testing emerges as a superior alternative to urine testing. Unlike urine tests, hair tests excel in providing a more extensive detection window, showcasing drug use patterns that span several months.
