Lab results

The laboratory results that contribute to a survival calculation are derived from blood tests like serum and plasma. Results from hemolyzed blood specimens should be excluded. If the precision level (that is, decimal points) of the raw data reported by the lab exceeds that of the Survival Calculator, simply round values as appropriate. In general, lab tests conducted within the first forty-eight hours of hospital admission offer the most reliable data for survival calculations.

BUN

Enter the highest BUN value recorded during the first forty-eight hours of admission. BUN units are mg/100 ml. If no BUN value is available, leave the default value of 12.

CPK

Enter the highest CPK value using units of IU/liter. If no CPK value is available, leave the age-specific default value.

Glucose

Enter the highest glucose value using units of mg/100 ml. If no glucose value is available, leave the age-specific default value.

pH

Enter the most abnormal pH value (either high or low). If no pH value is available, leave the default value of 7.4.

PO2

Enter the lowest PO2 value using units of mmHg. If no PO2 value is available, leave the default value of 80.

SGOT

Enter the highest SGOT value using units of u/liter. If no SGOT value is available, leave the default value of 12.

Blood count

Enter the highest white blood cell count (WBC) using units of cc/mm. If no WBC value is available, leave the age-specific default value.
