Hair Follicle Drug Testing - Shafter, CA

What it is, How it works

Hair testing has emerged as an effective method for detecting drug and alcohol consumption. By capturing biomarkers within the strands of growing hair, it offers a long-term record of alcohol and drug use. When collected near the scalp, hair can provide a detection window of up to around 3 months for alcohol and various drugs. The collection of hair is straightforward, relatively resistant to tampering, and easily transportable.

A 1.5-inch sample consisting of approximately 200 hair strands (roughly equivalent to the thickness of a #2 pencil) taken from the scalp will yield 100mg of hair, which is the ideal amount for both screening and confirmation processes. For EtG, additional tests, or panels exceeding 10, it is advised to collect 150mg of the sample. Using a jeweler’s scale is suggested for measuring the specimen. If scalp hair is not accessible, an equivalent quantity of body hair can be gathered. The term head hair pertains specifically to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial process of integrating a sample into the laboratory system. This step includes confirming the proper sealing and shipping of the sample, assigning a randomized Laboratory Accessioning Number (LAN), and completing any additional data entry not covered by an electronic chain of custody system.

Screening constitutes an initial evaluation for substances of abuse. Although Screening offers a cost-effective approach to exclude drug use for most samples, a positive result demands confirmation to hold validity in legal settings. Samples that show a presumptive positive during Screening necessitate a secondary verification.

Should a sample show a presumptive positive during Screening, additional hair is extracted from the initial sample to prepare for Extraction. During this phase, drugs are extracted from hair in significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening a challenge to perform.

Positive screening results require Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are subjected to washing before the confirmation process if required. The complete laboratory workflow from Accessioning to Confirmation is scrutinized according to the CAP (College of American Pathologists) Hair designation and compliant with the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can capture drug usage over a span of up to 90 days, unlike urine tests which offer a shorter detection period.
• Difficulty to cheat: It is extremely challenging to falsify a hair drug test, thus enhancing the reliability of the results.
• Provides historical data: The test can illustrate a trend of drug use over time rather than just indicating recent consumption.

Limitations:

• Cannot detect recent use: Detection of drugs in hair typically requires about 5-7 days.
• Cost: Hair drug tests often incur higher costs when compared to other testing methods.
• Variations in results: The concentration of drug metabolites in hair may vary due to factors like hair color and individual hair growth differences.

Note: Although commonly called "hair follicle tests", the analysis actually involves the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing is increasingly favored in Shafter, CA, over urine testing for several reasons. With superior detection accuracy and reliability, hair tests provide a clearer picture of substance use, leaving little room for error or deception.
