aConversion factor for units: Serum creatinine in mg/dL to µmol/L, ×88.4; blood urea nitrogen in mg/dL to mmol/L, ×0.357; glucose mg/dL to mmol/L, 0.05551.
bPlatelet count may not have been accurate. Although no clot was documented to have been found in the tube, repeat platelet count 6 h later was 129 k/cc3.
