Prothrombin is a factor in blood which helps clotting of blood. If ti is less, we may get bleeding and the doctor was checking if the child had less thrombocytes. However, I feel based on experience, the nose bleed came from nose picking, very commonly done by children.(prothrombin is a protein produced by your liver that helps your blood to clot. When you bleed, a series of chemicals (clotting factors) activate in a stepwise fashion. The end result is a clot which stops the bleeding. One step in the process is prothrombin turning into another protein called thrombin)
