Clotted blood is also known as a sentinel clot, and can provide an important clue as to the origin of bleeding. In anemic states, the density measurements may be lower, and this is also the case as the hematoma begins to resorb. Bile and simple ascites have lower measurements, usually 0-10 HU. With chylous ascites, fat fluid levels may be observed but the density remains low, as with simple ascites.\u003c/p\u003e","id":1488,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/1488","nextQuestionPath":"/articles/haemoperitoneum/questions/1485","relatedArticles":[{"id":21489,"title":"Sentinel clot sign","link":"/articles/sentinel-clot-sign?lang=us"},{"id":67058,"title":"Chylous ascites","link":"/articles/chylous-ascites?lang=us"}],"alsoUsedIn":[],"stem":"\u003cp\u003eA focus of abdominal fluid is measured as being 65 Hounsfield Units in density on CT.
