Hair Follicle Drug Testing - Roland, OK

What it is, How it works

Hair analysis has emerged as an effective means for detecting drug and alcohol consumption. It offers a historical record of substance use by locking in biomarkers within the strands' fibers as they grow. When gathered near the scalp, hair can reflect a use pattern for alcohol and other drugs for approximately 90 days. The collection process is straightforward, manipulation is relatively challenging, and shipping is convenient.

Obtaining a 1.5-inch hair specimen containing roughly 200 strands (similar in diameter to a #2 pencil) from the scalp provides 100mg of hair, which is optimal for analysis and verification. For EtG, additional tests, or screenings surpassing 10 panels, a 150mg sample is advisable. It's preferable to weigh the sample using a jeweler’s scale. If scalp hair is insufficient, the same amount of body hair can be used. References to head hair denote only scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The drug testing process in labs entails four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the integration of a specimen into the lab's workflow, ensuring it has been properly sealed and delivered, issuing a unique LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by digital chain of custody methods.

Screening performs a preliminary drug abuse inspection. Though this cost-efficient step can discount drug use for most samples, any positive findings need substantiation for legal admissibility. Samples presumptively positive in Screening must undergo additional validation.

For samples with presumptive positivity during Screening, more hair is retrieved from the original sample for Extraction. In this phase, drugs are isolated from the hair at significantly lower concentrations than those found using other techniques (e.g., urine or saliva), which contributes to the complexity of conducting hair drug tests.

Confirmation of positive results from screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positivity undergo washing before confirmation, if necessary. The entire procedure, spanning Accessioning to Confirmation, adheres to guidelines under the CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 certification criteria.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use for up to 90 days, significantly longer than urine tests, which offer shorter detection durations.
• Resistance to tampering: Hair drug tests are notably difficult to falsify, thus enhancing result reliability.
• Historical insight: These tests track a timeline of drug use over time, not just recent instances.

Limitations:

• Lacks recent usage detection: Drugs take about 5-7 days to become traceable in hair samples.
• Expense: Hair drug tests tend to be pricier than alternative testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations.

Note: Commonly called "hair follicle tests", these tests actually assess the hair strand itself, not the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing
