Creatinine storage should be carefully managed to maintain its stability. For short-term needs, store it at 2-8°C, often in a refrigerator for a few weeks. For long-term storage, freezing at -20°C is recommended to preserve its integrity over several months. Avoid repeated freeze-thaw cycles as they can significantly degrade the quality of the creatinine. Always label your storage containers clearly with the date of storage to monitor its shelf-life effectively.
FAQs & Answers
- What is the ideal temperature to store creatinine samples? Short-term storage of creatinine samples should be at 2-8°C, typically in a refrigerator, while long-term storage requires freezing at -20°C to maintain stability.
- Why should repeated freeze-thaw cycles be avoided for creatinine? Repeated freeze-thaw cycles can degrade the quality of creatinine samples, leading to inaccurate test results.
- How long can creatinine be stored refrigerated before freezing? Creatinine can be stored refrigerated at 2-8°C for a few weeks, but for longer storage periods, it is best to freeze the samples.
