Hair Follicle Drug Testing - Duncanville, AL

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair acts as a historical record, capturing biomarkers within its fibers. Samples cut near the scalp can reveal alcohol and other drug usage within a roughly 90-day timeframe. Hair is easy to gather, challenging to alter, and simple to transport.

To obtain the ideal screening and confirmation sample, collect a 1.5-inch portion of about 200 hair strands (resembling a #2 pencil’s thickness) closest to the scalp, yielding 100mg of hair. For EtG, add-ons, and/or tests exceeding 10 panels, a suggested specimen amount is 150mg. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair can't be retrieved, a comparable quantity of body hair can be used. The term "head hair" refers specifically to scalp hair, whereas "body hair" includes all other types (such as facial or axillary).

Process Overview

The key steps in processing a drug testing result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a laboratory's records. This process ensures proper sealing and shipping of the sample, assigns a LAN (Laboratory Accessioning Number), and completes any necessary supplementary data entry absent from an electronic chain of custody system.

Screening is a quick initial check for drugs of abuse. While it is an economical method for dismissing drug usage in most samples, a positive result in Screening requires confirmation for court admissibility. Any samples with presumptive positive results require secondary verification.

For samples with presumptive positives in the Screening stage, additional hair from the original specimen is prepared for Extraction. In this stage, drug substances are extracted from the hair's lower concentration than in other testing forms (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation for any positive Screening outcomes is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The laboratory process is thoroughly reviewed, from Accessioning to Confirmation, under the CAP designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Difficult to manipulate: Tampering with a hair drug test is highly challenging, thus enhancing result accuracy.
• Historical pattern: Provides insights into drug usage over time, not merely recent consumption.

Limitations:

• Delayed detection: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests are usually pricier compared to other testing methods.
• Result variability: Factors like hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", the analysis pertains to the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests surpass urine tests due to their superior detection capabilities and reliability. Unlike urine tests, hair tests provide a broader view of substance use, detecting usage patterns over an extended period.

Employers in Duncanville benefit from hair testing as it minimizes false negatives and provides a comprehensive perspective on an individual's drug history, unlike the more limited scope of urine testing.

Extended Detection Window
