🧪 The Final Check: What is Sterility Testing? 🔬
Sterility testing is a vital check used in the manufacturing of healthcare products (like injectable medicines, eye drops, or surgical devices) to confirm they are completely free from any viable microorganisms—no bacteria, no fungi, nothing alive!
It's the mandatory last line of defense to ensure a product is safe to use and won't cause infection when administered to a patient.
The Basics: The Gold Standard
The process typically involves taking samples from the product and placing them in different types of special liquid culture media (nutritive broths) designed to encourage the growth of any contaminating microbes.
The samples are incubated for a standard period (often 14 days).
