  • Measure airborne particles (both viable and non-viable) daily.

  • Check air pressure differences between rooms regularly.

• Surface Testing

  • Test critical work surfaces and equipment contact points weekly.

  • Track the effectiveness of cleaning procedures.

  • Regularly confirm contamination control measures are working.

• Quality Assurance Tools

  • Automated systems provide real-time alerts, log data, and assist with meeting compliance requirements.

  • These systems help maintain stable conditions and can cut microbial contamination by up to 90%.

Annual certifications ensure compliance with ISO 14644-1, covering HEPA filter performance and room classification standards. Staff must be trained in monitoring practices and know how to handle results that fall outside acceptable limits. This ensures quality control is upheld throughout all operations.

While monitoring maintains a controlled environment, thorough product testing is essential to confirm the safety and effectiveness of compounded medications.

3. Product Testing Requirements

Product testing is a key part of quality control in compounding pharmacies. It ensures medications adhere to strict safety and effectiveness standards. According to USP <797>, specific testing protocols are required to maintain compliance and protect patient safety.

Core Testing Requirements

Sterility and endotoxin testing are essential. Sterility testing, often done through membrane filtration, ensures no microbial contamination in sterile products. The LAL test checks that bacterial endotoxin levels stay below 0.5 EU/mL for injectables. Both are mandatory under USP <797>.

Physical and Chemical Analysis

Compounded medications also undergo checks for pH levels, weight and volume accuracy, active ingredient concentration, and visual inspections. These tests confirm stability, precision, and the absence of particulate matter.
