Hair Follicle Drug Testing - Parkville, PA

What it is, How it works

Hair analysis is increasingly regarded as an effective means for identifying drug and alcohol consumption. This method offers a prolonged overview of substance intake by encapsulating biomarkers within the growing hair strands. When gathered near the scalp, hair can deliver a detection timeframe of up to roughly three months for various substances. Collecting hair is straightforward, not easily tampered with, and convenient for transport.

A 1.5-inch segment, comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) gathered closest to the scalp, yields 100mg of hair, which is optimal for accurate screening and verification. For EtG supplements and/or tests exceeding 10 panels, 150mg of the sample is preferred. Using a jeweler’s scale to measure the specimen is advisable. If scalp hair is inaccessible, an equivalent quantity of body hair can be substituted. By head hair, we mean exclusively scalp hair, whereas body hair includes all other types (such as facial, axillary, etc.).

Process Overview

The laboratory process for drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into the laboratory system. This step involves confirming proper sample sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.

The Screening phase performs a preliminary rapid assessment for potential drug usage. While Screening is an economical approach to exclude drug use in most cases, a positive finding requires confirmation for court admissibility. Thus, samples that test positive in Screening must undergo secondary confirmation.

If the Screening stage suggests a positive result, additional hair is extracted from the initial specimen for the Extraction process. At this phase, the drugs are isolated from the hair at notably lower concentrations than other methods (e.g., urine or saliva), underscoring the complexity of hair drug screening procedures.

Positive screening confirmations are completed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test presumptively positive are cleaned prior to confirmation as needed. The comprehensive laboratory process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a span of up to 90 days, unlike urine tests that have a more limited detection window.
• Hard to manipulate: Tampering with hair drug tests is extremely challenging, enhancing result accuracy.
• Historical insight: These tests depict a timeline of drug use patterns, not merely recent occurrences.

Limitations:

• Cannot detect recent drug use: It takes roughly 5-7 days before drugs become detectable in hair.
• Expense: Hair drug testing tends to be costlier than other testing options.
• Result variability: Factors like hair color and individual hair growth differences can alter the concentration of drug metabolites in hair strands.

Note: Although often referred to as "hair follicle tests," the analysis actually examines the hair strand itself, not the scalp-anchored hair follicle.
