Hair Follicle Drug Testing - Perryville, PA

What it is, How it works

Hair analyses are increasingly recognized as a vital method for detecting substance and alcohol consumption. Hair can capture biomarkers within its strands, providing a retrospective account of substance use. When collected from the scalp, it presents an approximate 3-month detection period for substances. Collecting hair is straightforward, less susceptible to tampering, and convenient to dispatch.

A 1.5-inch sample encompassing around 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample size for both screening and confirmation. For EtG, supplementary tests, or tests exceeding 10 panels, a sample of 150mg is suggested. We advocate measuring the sample on a jeweler’s scale. In cases where scalp hair is impractical, an equivalent quantity of body hair can be gathered. References to head hair pertain exclusively to scalp hair, whereas body hair refers to all other types of hair (including facial, axillary, etc.).

Process Overview

The primary stages in lab processing for a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase where the sample is ushered into a laboratory’s system, involving the verification of the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody system.

Screening is the initial swift evaluation for substance misuse. Though it provides an economical method to negate drug usage for most samples, a positive screen must be confirmed for court admissibility. Samples that test presumptively positive during Screening necessitate a secondary confirmation.

If Screening yields a presumptive positive, additional hair is extracted from the initial sample for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to other methodologies (like urine or oral fluid), making hair drug screening the most intricate methodology to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS methods are utilized to confirm positive screening results. All presumptive positive samples undergo washing as needed before confirmation. The comprehensive laboratory procedure from Accessioning through Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal substance use up to 90 days, in contrast to urine tests, which have a shorter window.
• Resistance to manipulation: It's challenging to manipulate a hair drug test, ensuring result accuracy.
• Historical usage insight: Provides a profile of substance use over time, not merely recent usage.

Limitations:

• Inability to detect recent use: Drugs typically take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests usually incur higher costs compared to other drug testing approaches.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests", the evaluation actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Perryville, PA, hair follicle testing proves superior to urine testing due to enhanced detection accuracy.

• The drug detection window extends far beyond short phases covered by urine tests.
