Hair Follicle Drug Testing - Onycha, AL

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol use. It captures a long-term record of drug consumption by embedding biomarkers in the fibers of the developing hair strand. When collected near the scalp, hair offers a detection period of up to around 3 months for both alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A 1.5-inch segment containing approximately 200 hair strands (roughly equivalent to the circumference of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred amount for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advised. We suggest using a jeweler’s scale for specimen weighing. In the absence of scalp hair, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The core stages in the laboratory workflow of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the foundational processing of a sample into the laboratory system. This process ensures that the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry that an electronic chain of custody might not provide.

Screening is a preliminary rapid assessment for drugs of abuse. While Screening is a cost-effective approach for discounting drug usage in most samples, a positive result from Screening requires confirmation to be considered valid in legal settings. Samples with presumptive positive results during Screening necessitate additional confirmation.

When a sample indicates a presumptive positive result in Screening, additional hair is extracted from the initial specimen for the Extraction phase. Here, drugs are extracted from hair at much lower concentrations than found in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening compared to other methodologies.

Confirmation of any positive results from the screening phase is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation if necessary. The whole laboratory procedure, from Accessioning to Confirmation, is evaluated in compliance with the CAP (College of American Pathologists) Hair designation and according to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug testing can identify drug use for up to 90 days, in contrast to urine tests with shorter detection periods.
• Challenge to manipulate: It is quite challenging to fake a hair drug test, enhancing the accuracy of results.
• Historical insights: It reveals a timeline of drug use over an extended period, rather than just recent activity.

Limitations:

• Unable to detect recent use: Drugs become detectable in hair about 5-7 days after consumption.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Outcome variability: Factors like hair color and individual growth rates can impact drug metabolite concentrations in the hair.

Note: Although commonly referred to as "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle to urine testing in Onycha, AL, hair tests offer superior detection accuracy and reliability. This method provides a broad 90-day detection span, surpassing urine tests significantly.
