Protein S antigen (plasma)	Male: 70 - 140% of nml Female: 70 - 140% of nml	Male: 0.7 - 1.4 of nml Female: 0.7 - 1.4 of nml
Prothrombin time (PT)  (plasma)	9 - 12.5 seconds INR: International Normalized Ratio. The INR serves to normalize results obtained from different laboratories for the variable responsiveness of different thromboplastin reagents. Each thromboplastin is assigned an International Sensitivity Index (ISI) based on comparison to an international reference thromboplastin from the World Health Organization. The formula for calculating the INR is: INR = [patient's results/normal patient average](ISI)	9 - 12.5 seconds
Pyruvate (blood)	0.3 - 0.9 mg/dL	34 - 102 µmol/L
