Hair Follicle Drug Testing - Smithfield, NE

What it is, How it works

Utilizing hair testing has become recognized as an effective approach for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and other substances by embedding biomarkers within the strands during growth. When sampled near the scalp, hair can offer a detection window extending up to roughly three months for alcohol and other substances. The process of collecting hair is straightforward, relatively resistant to tampering, and easy to transport.

Obtaining a 1.5-inch specimen of approximately 200 hair strands (equivalent to a #2 pencil's diameter) closest to the scalp yields 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the specimen is advisable. It's recommended to use a jeweler’s scale for precise weighing of the specimen. In situations where scalp hair isn’t available, a comparable amount of body hair can be collected. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The key stages in lab processing for drug testing results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step of incorporating a sample into a lab’s system. This includes making sure that the sample was correctly sealed and dispatched, the random LAN (Laboratory Accessioning Number) is assigned, and any additional data entry required beyond what’s provided by an electronic chain of custody system is completed.

Screening consists of an initial rapid assessment for narcotics. Although it is a cost-efficient method to dismiss drug usage in the majority of samples, a positive screen needs verification to be valid in legal settings. Any samples that show a presumptive positive in Screening must undergo further confirmation.

If a presumptive positive is detected in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. Drugs are retrieved from hair at much lower concentrations than other methods such as urine or oral fluid, which is why hair drug testing is notably challenging.

To verify any positive screening finding, GC/MS, GC/MS/MS, or LC/MS/MS methodologies are employed. All presumptive positive specimens undergo washing pre-confirmation evidence as necessary. The total laboratory progression from Accessioning to Confirmation is assessed under both CAP (College of American Pathologists) Hair designation standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection timeframe: Hair drug assessments can identify substance usage for up to 90 days, relative to urine tests, which offer a briefer detection span.
• Challenging to manipulate: Manipulating hair drug tests is extremely difficult, resulting in more precise outcomes.
• Records historical substance usage: Capable of demonstrating a pattern of substance usage across time, not only recent consumption.

Limitations:

• Incapable of detecting recent consumption: Drugs become detectable in hair approximately 5-7 days after use.
• Higher cost: Hair drug assessments are typically pricier compared to alternative drug testing techniques.
• Result variability: Elements like hair pigmentation and individual growth differences can impact drug metabolite concentration in hair.

Note: Though frequently termed "hair follicle tests", the analysis focuses on the hair strand and not the hair follicle below the scalp.
