Compounded Sterile Preparation Technician (CSPT) Practice Exam

The fluid displacement test is not typically employed for testing the integrity of filters in pharmaceutical or sterile compounding settings. This method is more commonly associated with testing the volume capacity of containers or systems rather than assessing filter functionality. In contrast, the dioctyl phthalate (DOP) test, bubble point test, and visual inspection are all recognized methods for evaluating filter integrity. The DOP test involves using an aerosolized form of dioctyl phthalate to challenge the filter and analyze its ability to capture particles, while the bubble point test assesses the pressure at which the first bubbles emerge in a liquid, indicating pore sizes and filter integrity. Visual inspection allows technicians to examine the filter for any obvious signs of damage or defects, providing a straightforward method to ensure the filter is not compromised. Understanding these testing methods is essential for ensuring the safety and efficacy of sterile preparations, as compromised filters can lead to contamination and pose risks to patient safety.
