What the CSPT Exam Covers
The CSPT examination tests your ability to apply advanced sterile compounding knowledge in a clinical or institutional pharmacy setting. Understanding the following topic areas is essential for passing.
USP 797 Cleanroom Classifications
USP 797 defines the environmental requirements for compounding sterile preparations. The primary engineering control (PEC) — such as a laminar airflow workbench (LAFW) or biological safety cabinet (BSC) — must maintain ISO 5 air quality. The buffer area surrounding the PEC must meet ISO 7 standards, while the ante area must meet ISO 8. Horizontal-flow LAFWs are used for non-hazardous drug preparations; BSCs with vertical airflow are required for hazardous drug compounding to protect the compounder.
Beyond-Use Dating Under Updated USP 797
The updated USP 797 chapter categorizes CSPs into three sterility categories. Category 1 CSPs are prepared in conditions that do not meet ISO 5 requirements and carry short BUDs — 12 hours at controlled room temperature or 24 hours refrigerated. Category 2 CSPs are prepared in ISO 5 PECs with supporting ISO 7/ISO 8 environments and may receive extended BUDs based on sterility testing. Category 3 CSPs have the most stringent environmental and testing requirements and may qualify for the longest BUDs. Knowing BUD limits for each category is a high-frequency exam topic.
Personnel Competency and Garbing Requirements
Compounding personnel must demonstrate competency through garbing evaluations, hand hygiene technique assessments, gloved fingertip sampling, and media fill testing. Media fill tests simulate aseptic technique using growth media instead of actual drug product — any growth in the media indicates a breach of aseptic technique. Personnel must complete initial competency assessments and periodic reassessments per USP 797 requirements.
Aseptic Technique and Critical Sites
A critical site is any surface or opening that is at risk for contamination and could affect the sterility of a CSP. This includes the needle tip, vial septum, ampule neck, and syringe tip. Proper aseptic technique requires disinfecting all critical sites with 70% IPA and allowing full contact time before manipulation. Vials are accessed using a coring-prevention technique; ampules require a filter needle or filter straw during withdrawal.
Environmental Monitoring
Cleanroom environmental monitoring includes viable air sampling (active and passive), surface sampling using contact plates or swabs, and non-viable particle counts. Temperature, humidity, and pressure differential logs must be maintained. ISO 5 areas require more frequent monitoring than ISO 7 or ISO 8 areas. Out-of-specification results trigger corrective action documentation.
USP 800 Hazardous Drug Handling
USP 800 governs the handling of hazardous drugs (HDs) listed on the NIOSH hazardous drug list. Requirements include negative pressure rooms for HDs, use of closed-system transfer devices (CSTDs), and a four-step decontamination process: deactivation, decontamination, cleaning, and disinfection. Personnel handling HDs must use appropriate PPE including double gloves, a chemotherapy gown, and respiratory protection where indicated.

Sample CSPT - Compounded Sterile Preparation Technician Practice Questions
Try these questions from our free CSPT - Compounded Sterile Preparation Technician practice tests. The correct answer and an explanation follow each question.
When should a compounded sterile preparation be discarded if it was prepared in a non-sterile-to-sterile compounding process?
- A. Only when the BUD has passed
- B. Whenever there is visible turbidity, particulate matter, or container damage
- C. Only if the patient reports adverse effects
- D. After 30 days regardless of storage conditions
Answer: B. Whenever there is visible turbidity, particulate matter, or container damage
Any visible turbidity, particulate matter, or container damage is grounds for immediate discard regardless of the BUD.
After filtering a compounded sterile preparation through a 0.22-micron membrane filter, a bubble point integrity test is performed. What does this test confirm?
- A. That the filter removed all particulate matter above 0.22 microns
- B. That the filter membrane is intact and was not compromised during filtration
- C. That the filtrate is free of endotoxins
- D. That the drug concentration did not change during filtration
Answer: B. That the filter membrane is intact and was not compromised during filtration
The bubble point integrity test verifies that the filter membrane has not been punctured, torn, or otherwise compromised. A breached filter could allow microorganisms to pass through, invalidating the sterilization process. USP requires post-filtration integrity testing for high-risk CSPs.
A CSPT technician notices that the label on a compounded product lists a dose of '10 mcg' but the preparation record indicates '10 mg.' What should the technician do?
- A. Dispense the product using clinical judgment about which is correct
- B. Immediately hold the product and clarify the discrepancy with the pharmacist
- C. Assume the label is correct since it was printed last
- D. Correct the preparation record to match the label without verification
Answer: B. Immediately hold the product and clarify the discrepancy with the pharmacist
Any discrepancy between the label and preparation record requires immediate clarification with the pharmacist before the product is dispensed.
What should be done if a compounded sterile preparation fails a quality control test?
- A. Release it for patient use with a warning label
- B. Store it separately for future testing
- C. Dilute the preparation to meet standards
- D. Discard the preparation and investigate the cause of failure
Answer: D. Discard the preparation and investigate the cause of failure
Failed CSPs should be discarded, and the cause of failure should be investigated to prevent recurrence.
