Pre-transfusion laboratory values of Hemoglobin, INR, and total Platelet Count are compared by Cardiac surgical categories of Bi-ventricular or Single Ventricle Diagnosis across operative settings (pre-operative, operative, or post-operative). Mean, minimum and Maximum values, and percentage distribution are shown. (P_1 =1^st percentile, P_50=50^th percentile (median), P_99=99^th percentile)
