Hair Follicle Drug Testing - Killian, LA

What it is, How it works

Hair analysis is increasingly valued as an effective method for detecting drug and alcohol consumption. Hair captures a historical record of alcohol and drug intake by embedding biomarkers within the fiber structure of the growing hair. Sampling hair close to the scalp can reveal a drug and alcohol detection timeline of roughly three months. Collecting hair is straightforward, relatively tamper-proof, and convenient for transport.

A 1.5-inch hair sample consisting of approximately 200 strands (comparable to the girth of a #2 pencil) sourced near the scalp yields 100mg of hair, ideal for both screening and confirmatory tests. For testing that includes EtG, add-ons, or panels exceeding ten, a 150mg specimen is preferred. Utilizing a jeweler's scale for weighing the sample is advised. In cases where scalp hair is absent, an equivalent volume of body hair is suitable. Here, "head hair" refers exclusively to scalp hair. "Body hair" includes all other hair types such as facial, axillary, etc.

Process Overview

The laboratory processing of drug test results involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into the laboratory system. This includes confirming the sample's sealing and proper shipment, assigning it a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody system.

Screening offers a preliminary and rapid assessment for drugs of abuse. While it's an economical method for negating drug use in most samples, a positive outcome requires confirmation before being court-admissible. Presumptive positives identified during Screening necessitate a secondary verification.

For samples that test presumptively positive during Screening, additional strands are extracted from the initial sample for further processing. The Extraction phase retrieves drugs from hair at significantly lower concentrations compared to other methodologies (such as urine or oral fluids), presenting hair drug screening as a challenging methodology.

Verification of any positive results from Screening is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positives are cleansed before the Confirmation stage as needed. The process from Accessioning to Confirmation is conducted in compliance with both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a 90-day span, contrasting with urine tests that have a narrower detection frame.
• Challenge to deceive: The inherent difficulty in evading a hair drug test enhances result accuracy.
• Offers historical insight: It traces drug usage patterns over time, beyond recent consumption.

Limitations:

• Incapable of detecting recent use: It takes about 5-7 days for drugs to become traceable in hair.
• Expenses: Hair drug tests typically incur greater costs compared to alternative testing methods.
• Result variability: Variables such as hair color and individual hair growth variations can influence drug metabolite concentrations in the hair.

Note: Though often labeled as "hair follicle tests", the actual analysis involves the hair strand rather than the follicle underneath the scalp.
