Von Willebrand factor (vWF) is one of several proteins in the body's blood clotting system that work together, and in sequence, to stop bleeding. Von Willebrand factor tests help investigate excessive bleeding.
Peritoneal fluid is the liquid in the space surrounding the organs in the abdomen. Lab tests performed on this fluid help diagnose the cause of ascites (fluid build-up) or peritonitis (inflammation of the peritoneum).
Pericardial fluid analysis is used to help diagnose the cause of inflammation of the pericardium (pericarditis) and/or fluid accumulation around the heart (pericardial effusion).
Lactoferrin is protein released into the stool when there is inflammation in the digestive tract. A stool lactoferrin test may be used to detect inflammatory bowel disease (IBD) and distinguish between IBD and non-inflammatory conditions.
Janus Kinase 2 (JAK2) gene mutations are associated with bone marrow disorders called myeloproliferative neoplasms (MPNs) caused by the production of too many blood cells. JAK2 mutation tests help diagnose MPNs.
Heparin is a drug used to treat people who have dangerous blood clots or to prevent clots in those with a high risk of developing them. Heparin anti-Xa blood tests are sometimes used to monitor and adjust standard heparin therapy.
Des-gamma-carboxy prothrombin (DCP) is an abnormal form of prothrombin, a clotting factor produced by the liver. A DCP blood test may be used to monitor the effectiveness of treatment for hepatocellular carcinoma (HCC), a type of liver cancer.
