Hair Follicle Drug Testing - Shrewsbury, PA

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair serves as a chronicler of drug and alcohol usage by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair can offer up to around a 3-month timeframe for detecting alcohol and drug presence. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches containing about 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp will yield 100mg, which is the optimal quantity for both screening and verification. For EtG, enhancements, and/or tests exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not obtainable, an equivalent quantity of body hair can be used instead. When we mention head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The procedure for laboratory processing of a drug test outcome consists chiefly of four phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves preparing a sample for entry into a lab's system. This step encompasses ensuring the sample is properly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and finalizing any leftover data entry not covered by an electronic chain of custody system.

Screening initiates a preliminary assessment for substances of abuse. Although Screening offers a cost-efficient way to exclude drug usage in most samples, a positive screening result mandates further confirmation to be viable in legal settings. Samples with presumptive positive results during Screening require subsequent verification.

For samples testing positive in the Screening phase, additional hair is taken from the original specimen for the Extraction step. In Extraction, drugs are isolated from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), making hair drug screening notably complex to execute.

Confirmation for any screening positive is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive are pre-washed as needed before confirmation. The complete laboratory procedure from Accessioning to Confirmation undergoes review in accordance with the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the capability of identifying drug use up to 90 days, unlike urine tests, which have a shorter window.
• Difficult to subvert: Hair drug tests present a substantial challenge for cheating, improving result reliability.
• Historical consumption insights: They reveal a timeline of drug usage patterns over time, beyond just recent intake.

Limitations:

• Cannot recognize recent intake: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug tests typically incur higher costs compared to alternative drug testing techniques.
• Outcome variability: Variables such as hair coloration and personal hair growth rates can influence drug metabolite levels found in hair.

Note: Although sometimes labeled as "hair follicle tests", these tests analyze the strand, not the follicle embedded in the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Shrewsbury, PA, the advantages of hair follicle testing over urine tests are evident. Hair tests provide superior detection accuracy, offering a more reliable insight into drug use.
