Comprehensive Alcohol Testing Solutions

We offer multiple alcohol testing options to match your personal or professional needs:

  • Breath Alcohol Test
    A quick and common test used by law enforcement and employers. It measures Blood Alcohol Concentration (BAC) using a simple breath sample.

  • Saliva Alcohol Test
    A fast, non-invasive test that detects alcohol use within the past 24 hours—ideal for immediate screenings.

  • Hair Alcohol Test
    Designed to detect long-term alcohol use over the past 90 days. This option is often used for more in-depth assessments.

Each testing method gives valuable insight into alcohol consumption and helps ensure you're using the right tool for your unique situation—whether for routine checks, legal compliance, or rehab monitoring.

Our Occupational Health Clinic Team specializes in diagnosing and treating work related injuries with high quality, prompt and affordable care. Our excellent physicians and staff have an extensive knowledge of the complex landscape of workers’ compensation in California, critical to successful injury management. We utilize a return to work program that recognizes the needs of both the employer and injured worker. We understand the employers’ need to minimize the disruption and expense which workplace injuries may cause. We will work with you to develop an alternative-duty program to ensure your employees can continue working during recovery. Our team of professionals will visit your company for worksite evaluations and safety recommendations before an injury occurs, promoting worksite safety. Having St Rose Hospital Emergency Room as back up for injuries that occur after our clinic hours, provides an additional means to care for your employees.
