Assessment of clotting time Aim: to determine time taken for clotting by Capillary tube method Principle: Formation of fibrin threads after a series of reactions between Several clotting factors. Requirements:- Capillary tube method, Watch, Cotton, Spirit lancet, Coagulation time may be performed by Capillary blood or venous blood method Capillary blood methods:- Slide method (4-10 mins). Capillary tube method (3-9 ming). Dale and laid lane methods Venous blood method:- ① dee and white blood (5-15 min). Howell method Silicon tube method. Procedure:- A capillary tube about loom length is used. Clean the fingertip with alcohol. Dry and make a deep prick. Note the time as the blood Starts to flows. Drane immediately into capillary tube by placing one end of The thread of clot us. first seen the time from the capillary tube on the drop of blood. See that at 3/4th of the capillary tube is filled with blood after about 2 min Starts Snapping the capillary tube of an The interval of 30 See. nothing Wether a fibrin thread has been formed between. Snapped ends. Note time. Assessment of Bleeding time Aim: To assess the time taken to assess bleeding after finger puncture! Principle:- Haemostatic mechanisms helps to Stoppage of bleeding Which needs sometime is determined. Requirements: Filter paper, water, Spirit, cotton and lancet. 1. the bleeding time can be performed by following methods. . Duke method (2-5 min), Macfarlane method. IVY method (1-7 min), Mielke method. Template method (2.5-10min), Simplate method.. procedure:-! Clean the fingertip with alcohol and allow it to dry make a quick deep prick with a lancet. Blood will start flowing. Note the time of blood flow immediately. With a filter paper absorb blood coming out every quarts minute (15 see) using a fresh part of filter paper for each touch.

Note the bleeding time the moment the blood starts to flow to bleeding Stops. = Normal Nathe:- (2-5 mins). Bleeding time increases in Scurvy, purpura, glanzmanins disease, infectious mono nueles fis, and multiple myeloma. Result: The bleeding time of the given blood sample is 10022 1:45 ming.
