Bleeding and clotting time in different blood groups

Coagulation Tests

To diagnose a bleeding disorder, your doctor will ask you about your symptoms and medical history. In most cases, patients may develop dermal or mucosal bleeding or excessive bleeding after trauma or surgery procedures.

In this study all incisions were made by a lancet and standard filter papers were selected to draw off the blood. Table 1 Estimated sample size according to different powers the used numbers in the estimated sample size was males and females with 0.

It is seen that the blood stains on the filter paper get smaller to disappear finally when bleeding stops. It is hence necessary to determine normal BT in each geographical zone.

One of them is its wide reference range minutes which has been caused by different races and ages and different areas throughout the world. The most important advantage of BT test is its ability to evaluate normal body homeostasis and the role of vessels in this process.

If you have experience excessive bleeding, the procedure will be carefully monitored. These transfusions must be done in a hospital. Values can vary from one laboratory to another, so ask your doctor to explain the results.

Most people feel a minor stick. Other treatments Some bleeding disorders may be treated with topical products or nasal sprays. It may take longer if you take blood thinners.

Bleeding Disorders

Thrombin time Thrombin time measures how well fibrinogen is working. The side effects of a coagulation test are generally minor.

The normal BT values run in the range of minutes. The results of this test are prepared immediately and need very few amount of blood. They were then sent to the research center along with the filled time tables to be reevaluated by the second observer.

In this method, a blood pressure cuff is placed on upper arm and is then inflated to 40 mm Hg. Note the time stop the stop-watch. The collected blotting papers were encoded. The collected data was then recalculated by another observer and the final values were recorded in the main research center at Lorestan University of Medical Sciences Iran.

Bleeding usually lasts between one to nine minutes. It is not affected by the method of sampling and anticoagulants, either. You may need to discontinue taking certain medications prior to the test. Under sterile conditions make a deep prick on the forearm just below the elbow. RESULTS In this study, 33 normal participants 20 women and 13 men were divided into four age groups of, and over 64 years old.

Common complications of bleeding disorders include: Normal value is2 to 7 minutes 1. All sample takers were trained for performing the test.

A standard filter paper should be used every 30 seconds to draw off it until the blood completely stops.Learn about the different types of bleeding disorders and how they’re treated.

or XII deficiencies are bleeding disorders related to blood clotting problems or abnormal bleeding problems. Bleeding time and clotting time among various Blood groups and also to identify any gender difference among the same.

This is a cross sectional study including. Jan 06,  · Determination of normal range of bleeding time in rural and urban residents of Borujerd, Iran: A pilot study A research on the effects of different blood groups on BT in participants showed that the von Willebrand's factor in the plasma of subjects with blood group O was lower than other blood groups.

Bleeding time and clotting time are not the same. Bleeding time depends on the integrity of platelets and vessel walls, whereas clotting time depends on the availability of coagulation factors. In coagulation disorders like haemophilia, clotting time is prolonged but bleeding time remains normal. standard antisera and bleeding time and clotting time were estimated by Duke method and capillary tube method respectively.

Finally bleeding time and clotting time of different blood groups were compared and statistical analysis was done.

Results: In present study population O group was found in. The time taken for blood to clot mainly reflects the time required for the generation of thrombin in this manner. If the plasma concentration of prothrombin or of some of the other factors is low (or if the factor is absent, or functionally inactive), clotting time will be prolonged.
