Hair Follicle Drug Testing - Brentwood, CA

What it is, How it works

The utilization of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair acts as a repository for a prolonged timeline of alcohol and drug consumption by embedding biomarkers within the strands as they grow. When hair is obtained near the scalp, it can offer a detection range of approximately three months for alcohol and drug use. The collection process is straightforward, relatively resistant to tampering, and provides ease of transport.

A sample measuring 1.5 inches with roughly 200 hair strands (comparable to the thickness of a #2 pencil) taken nearest to the scalp yields 100mg of hair, which is optimal for initial screening and further analysis. For EtG evaluations, supplemental tests, or assessments exceeding 10 panels, a specimen weight of 150mg is advisable. It is advisable to determine the specimen's weight using a jeweler’s scale. In cases where scalp hair is absent, a comparable amount of body hair can be utilized. When referencing head hair, it pertains exclusively to scalp hair, whereas body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

The primary stages in laboratory drug test result processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the integration of a sample into the laboratory framework. This phase ensures that the sample is appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and addresses any supplemental data input not already available through an electronic chain of custody system.

Screening offers an initial preliminary evaluation for substances of abuse. Screening serves as a cost-effective approach to exclude drug usage in the majority of cases; however, any positive findings require confirmation for legal validity. Samples yielding presumptive positive results during Screening necessitate further confirmation.

If a sample exhibits a presumptive positive result during Screening, additional hair is extracted from the initial specimen for the Extraction phase. At this juncture, drugs are isolated from hair at concentrations significantly lower than other methods (e.g., urine or oral fluid), which underscores the complexity of hair drug screening.

Confirmation of any positive results identified during screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning through Confirmation is conducted under the oversight of the CAP (College of American Pathologists) Hair designation in alignment with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for as long as 90 days, whereas urine tests offer a more limited detection timeframe.
• Increased challenge to manipulate results: Manipulating the outcome of a hair drug test is exceedingly challenging, lending greater accuracy to the findings.
• Chronological data provision: It can depict a timeline of drug use, indicating habitual patterns rather than just recent consumption.

Limitations:

• Incapable of detecting immediate usage: Drugs require approximately 5-7 days to become traceable in hair.
• Expense: Hair drug testing generally incurs higher costs compared to alternative methods.
• Result variability: Factors such as hair color and personal hair growth differences can influence drug metabolite concentrations within hair.

Note: Commonly termed "hair follicle tests", the procedure actually analyzes the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Brentwood, CA, supersedes traditional urine tests by offering superior detection opportunities. Its enhanced accuracy captures a more comprehensive substance history, surpassing the limitations of short-term urine tests.
