bleeding time tests the function of ____
platelets
materials in bleeding time
70% isopropyl alcohol

3 methods in bleeding time
duke’s method
modified ivy’s method
copley-lalitch method
the lobe of the ear is the site of choice for puncture. it should be warmed before the test or before incision is made. then take bleeding time
duke’s method
reference range for duke’s method
2-4 minutes
capillary puncture is standardized and the average of bleeding time from three separate incisions in the forearm is noted. this provides a very accurate technique if the incisions are identical
modified ivy’s method
in modified ivy’s method, what pressure is used on the sphygmomanometer?
40mmHg
reference range for modified ivy’s method
1/2 - 7 minutes
