Final answer:
Quality assurance in sterile product compounding includes checking equipment accuracy and precision, performing validation runs, and using HPLC for compound concentration verification.
Step-by-step explanation:
An example of quality assurance and validation testing performed by pharmacy technicians (PT) who compound sterile products involves checking the precision and accuracy of the compounding equipment used to prepare the medications. To ensure that the equipment dispenses the correct volume of a drug, a quality control chemist would test the machines multiple times, as shown in the scenario where a chemist checks the volume of cough syrup dispensed by filling several bottles and measuring the volumes.
This process may include validation runs, assessment of extraction recovery, and even bioanalytical methods like High-Performance Liquid Chromatography (HPLC) to confirm the stability and concentration of the compounds being tested.
