Hair Follicle Drug Testing - Atwood, CA

What it is, How it works

Hair testing is recognized as an effective method for identifying the use of drugs and alcohol. Hair offers a comprehensive historical record of alcohol and drugs by capturing biomarkers within the fibers of the hair strands as they grow. When hair is taken close to the scalp, it can reveal a detection period of nearly 90 days for alcohol and drugs. The collection process for hair is straightforward, difficult to tamper with, and easily transportable.

A 1.5-inch cutting of approximately 200 hairs (comparable to a #2 pencil's diameter) from the scalp offers 100mg of hair, the preferred amount for analysis. For EtG, additional analysis, or panels greater than 10, a 150mg specimen is advisable. We suggest weighing the hairs on a jeweler’s scale. If scalp hair is not available, an equivalent portion of body hair is acceptable. References to head hair indicate solely scalp hair. Body hair encompasses all other hair types (such as facial and axillary).

Process Overview

There are four primary phases in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of entering a sample into a lab's database. This step includes checking that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any required data that isn't covered by an electronic chain-of-custody system.

Screening entails a preliminary examination for illicit drugs. Although Screening is a cost-efficient method to dismiss drug usage in most cases, a positive result must be verified to be legally valid. Any samples with a presumptive positive from Screening necessitate extra confirmation.

In cases where a sample shows a presumptive positive during Screening, additional hair is retrieved from the initial specimen to ready for Extraction. This phase involves isolating drugs from hair at notably lower concentrations compared to other techniques (such as urine or oral fluids), which renders hair drug testing the most complex methodology.

Confirmation of any positive screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, in contrast to urine tests, which have a shorter detection period.
• Tough to deceive: Cheating on a hair drug test is exceedingly difficult, enhancing the test's accuracy.
• Delivers historical context: It can indicate a trend of drug use over time, not just recent usage.

Limitations:

• Incapable of detecting recent consumption: Drugs require about 5-7 days to become evident in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing techniques.
• Result variations: Elements such as hair color and personal differences in hair growth can impact drug metabolite levels in the hair.

Note: While commonly labeled as "hair follicle tests," the examination focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Atwood, CA, surpasses urine testing by offering broader detection capabilities and increased accuracy.
