What are potential consequences of not centrifuging specimens in a timely manner?
Understand the Problem
The question is asking about the possible effects or results of delaying the centrifugation of laboratory specimens. It seeks to understand how timing affects the integrity and reliability of the specimens after they are collected.
Answer
Delayed centrifugation can cause cell lysis, inaccurate results, and stability issues.
Delayed centrifugation can cause cell lysis, release of intracellular content, increases in analytes, inaccurate test results, and changes in serum or plasma stability.
Answer for screen readers
Delayed centrifugation can cause cell lysis, release of intracellular content, increases in analytes, inaccurate test results, and changes in serum or plasma stability.
More Information
Delayed centrifugation can lead to issues such as increased analytes due to cell lysis and contamination from intracellular contents, causing inaccurate biochemical results.
Tips
A common mistake is not considering the clotting time before centrifuging serum samples. Once clotting is complete, centrifuge within the recommended time.
