Hair Follicle Drug Testing - Elizabeth, LA

What it is, How it works

Hair testing is widely recognized as a potent method for identifying alcohol and drug consumption. It offers an extended history of substance use by capturing biomarkers within the hair's growing fibers. A hair sample taken close to the scalp can provide a detection window of about 3 months for drug and alcohol presence. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch section of approximately 200 hair strands (similar in size to a #2 pencil) cut nearest to the scalp yields about 100mg of hair, which is optimal for both screening and confirmation. For EtG, supplementary tests, or tests beyond 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale to weigh the specimen precisely. Should scalp hair be unavailable, a similar quantity of body hair is acceptable. Here, head hair refers exclusively to scalp hair, and body hair includes facial, axillary, and other types.

Process Overview

The laboratory drug test processing consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase that incorporates the sample into the lab's system, confirming it was properly sealed and transported, assigning a unique Laboratory Accessioning Number (LAN), and completing any required data entry when an electronic chain of custody system doesn't provide such information.

Screening is a preliminary, efficient method to detect substance abuse. Although cost-effective and able to rule out drug usage in many cases, a positive screen requires confirmation to be considered valid in legal contexts. Any samples that test presumptively positive during screening need further verification.

For samples that are presumptively positive in Screening, additional hair is retrieved from the initial sample for Extraction. In this stage, drugs are isolated from the hair at a much lower concentration than other methods like urine or oral fluid testing, making hair drug screening the most sophisticated method.

Confirmation of positive screening results is conducted through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing prior to confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection time frame: Hair tests can identify drug use up to 90 days, unlike urine tests with shorter detection periods.
• Difficult to manipulate: Cheating on a hair drug test is very hard, ensuring more accurate results.
• Historical usage data: It reveals a timeline of drug use, not just recent activity.

Limitations:

• Cannot detect recent usage: Drugs become detectable in hair after around 5-7 days.
• Expense: Typically, hair drug tests are costlier than alternative testing methods.
• Result variations: Drug metabolite concentration in hair can be influenced by individual hair color and growth rate.

Note: Despite the common term "hair follicle tests", the analysis is performed on the hair strand itself and not on the follicle underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
