The Bleeding Time (BT) & Clotting Time (CT) routine test assesses your blood’s ability to clot, with BT measuring how long a small cut bleeds (normal 2-7 min, platelet function) and CT measuring tube clotting (normal 5-15 min, coagulation factors), helping diagnose bleeding/clotting disorders before surgery or for unexplained bleeding, though some modern labs use more advanced tests like PT/INR
