Hair Follicle Drug Testing - Houma, LA

What it is, How it works

Hair analysis is regarded as a significant method for identifying drug and alcohol consumption. The hair stores a timeline of alcohol and drug intake by capturing markers within the strands. If taken near the scalp, hair can offer an observation window of up to roughly three months for substances. The collection process for hair is straightforward, moderately resistant to tampering, and easy to transport.

A sample measuring 1.5 inches with around 200 hair strands (roughly resembling the thickness of a #2 pencil) at the area closest to the scalp provides 100mg, which is optimal for both screening and validation. For EtG, additional tests, and/or panels exceeding 10, a sample weighing 150mg is advised. It’s recommended to use a jeweler’s scale for precise weighing of the sample. When scalp hair is not an option, similar quantities of body hair can be used. Reference to head hair pertains solely to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The key stages in lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase in entering a sample into a lab's framework. This step involves ensuring the sample's seal and shipment conditions, assigning a laboratory accessioning number (LAN) randomly, and completing any additional informational entry not covered by an electronic custody system.

Screening serves as a preliminary rapid assessment for substance abuse. Screening is a budget-friendly method to eliminate drug use in most samples, although a positive result requires confirmation for court validity. Samples with positive screening outcomes need definitive confirmation.

If screening results indicate a likely positive, additional hair is utilized from the original sample for Extraction. At this phase, substances are withdrawn from hair at significantly reduced concentrations compared to other methods (such as urine or oral fluids), hence making hair drug testing exceptionally challenging.

Any affirmative screening outcome undergoes verification using GC/MS, GC/MS/MS or LC/MS/MS. Samples displaying presumptive positives are cleaned before confirmation if necessary. The complete procedure from Accessioning to Confirmation is carried out under the CAP (College of American Pathologists) Hair guidelines, conforming to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations detect usage for as long as 90 days, unlike urine tests which have a briefer detection span.
• Reduced likelihood of tampering: Cheating a hair test is extremely challenging, enhancing result accuracy.
• Historical insight: Offers a usage pattern over time, beyond just recent data.

Limitations:

• Incapable of identifying recent usage: A timeframe of about 5-7 days is required for drugs to appear in hair.
• Expense: Hair testing typically costs more than alternative methods of drug testing.
• Result variation: Factors like hair color and personal differences in hair growth may influence metabolites concentration in hair.

Note: Despite commonly being called "hair follicle tests", the analysis focuses on strands, not the follicle beneath the scalp
