GENDER-BASED DIFFERENCES IN THE BLEEDING TIME AND CLOTTING TIME AND THEIR RELATIONSHIP WITH THE BLOOD GROUPS

It is extraordinary that 100 years after the work of Karl Landsteiner (1900) on blood grouping, the scene is different and numerous studies have been carried out on association of blood groups with diseases. METHODS In order to add to the existing knowledge on the subject, we studied 150 normal healthy subjects (Medical students) to find out the probable relationship between Blood groups and gender with bleeding time & clotting time. Blood group determination was done by mixing the sample of blood with antisera A and B and Anti D antisera and was confirmed by looking for clumping of RBCs under the microscope. Bleeding time was estimated by Duke Method and clotting time was estimated by capillary tube method. RESULTS In our study, we observed that the O blood group individuals are having greater bleeding time and clotting time than the non O blood group individuals. Females had more bleeding time and clotting time than males. CONCLUSION So, through this research, the fact that there is a Gender based difference in the Bleeding time and Clotting time is pro ven. The relationship between bleeding time and clotting time with the blood groups was also studied.
