Hair Follicle Drug Testing - San Lorenzo Valley, CA

What it is, How it works

Hair assessments are now recognized as a robust means for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and compound usage by embedding biomarkers within the strands as they grow. When harvested proximal to the scalp, such samples can yield a detection interval of nearly three months for alcohol and substances. The collection of hair is straightforward, resistant to tampering, and simple to transport.

A 1.5-inch section comprising roughly 200 hair strands (comparable to a #2 pencil) nearest the scalp will yield around 100mg of hair, which is an optimal amount for preliminary and confirmatory tests. For EtG, supplemental, or analyses exceeding 10 panels, 150mg of the sample is advisable. The measurement of the sample should be carried out using a jeweler’s scale. If scalp hair is not accessible, a similar amount of body hair might be utilized. In reference to head hair, it strictly pertains to scalp hair. Body hair denotes all other types of hair (facial, axillary, etc.).

Process Overview

The primary phases in the lab processing of a drug analysis outcome encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning focuses on the initial integration of a sample into a lab’s system. This step ensures the sample is correctly sealed and transported, designates a unique LAN (Laboratory Accessioning Number), and completes extra data input absent from an electronic chain of custody mechanism.

Screening conducts a preliminary swift assessment for substance misuse. Screening is a budget-friendly method to exclude drug presence in the majority of specimens, yet a positive result requires validation to be legally acceptable. Samples showing presumptive positivity in Screening mandate an additional confirmation.

In cases where a sample shows presumptive positivity during the Screening phase, additional strands are extracted from the preliminary sample and readied for Extraction. Here, drugs are retrieved from hair at a notably lower concentration compared to different methodologies (e.g., urine or oral fluid), which is why hair analysis is the most intricate methodology to execute.

Confirmation of any positive screening assessment utilizes GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples undergo washing before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug evaluations can identify drug consumption for up to 90 days, unlike urine tests, which have a shorter detection window.
• Hard to manipulate: Manipulating a hair drug evaluation is challenging, enhancing result reliability.
• Yields historical insight: It reveals a usage pattern over time rather than only recent consumption.

Limitations:

• Incapable of detecting recent intake: Approximately 5-7 days are needed for drugs to manifest in hair.
• Expense: Hair drug analyses are typically more costly than other testing approaches.
• Result discrepancies: Factors like hair hue and personal growth differences might influence the drug metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests", the examination itself is of the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In San Lorenzo Valley, CA, hair follicle testing stands out when compared to urine testing due to its superior detection capabilities. While urine tests are common, hair testing offers greater accuracy and reliability by reflecting a longer history of drug use.
