May permit 48-h refrigerated storage for convenient NSE/S-100 sampling in cardiac surgery; leaves open broader validation.
Does storing blood samples at room temperature or 4 degrees C for up to 48 hours affect the measured levels of S-100 and NSE in patients undergoing cardiac surgery?
Blood samples for NSE and S-100 assays can be stored at 4 degrees C for up to 48 hours without affecting measured levels, allowing for more convenient serial sampling during cardiac surgery.
