![]() ![]() because they have had a stroke or heart attack previously), anticoagulants (medicines which thin the blood and reduce the formation of clots), are used to minimise the risk of blood clots forming. Therefore, when a person is at high risk of one of the above conditions (e.g. These conditions are all potentially fatal. In thromboembolic disease, fragments of blood clots dislodge and circulate in the blood, potentially obstructing blood vessels in the lungs and causing pulmonary embolism, or vessels in the heart and causing heart attack, or in the brain and causing stroke. When this occurs, a person may be at an increased risk of thromboembolic disease. However, there are several conditions that can cause blood clots to form in the absence of active bleeding. Normally, clotting only occurs when there is blood loss from a damaged blood vessel. They are called this because they contribute to the formation of a blood clot.įor more information, see Blood Function and Composition. When damage occurs to a blood vessel, a series of reactions take place involving substances found in the blood known as clotting factors.

In general it is difficult to detect infection before day 7 because, especially with WBC alone(2,3). However post operatively patients may demonstrate increases up of 3,000uL during the first 2 days due to the systemic response to imposed trauma (surgery)(2,3). **No current accepted guidelines exist for upper limit cut off scores.
