Haemochromatosis is protean in its manifestations, i.e., often presenting with signs or symptoms suggestive of other diagnoses that affect specific organ systems.Many of the signs and symptoms below are uncommon, and most patients with the hereditary form of haemochromatosis do not show any overt signs of disease nor do they have premature morbidity, if they are diagnosed early, but, more ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Pancreatic diseases are diseases that affect the pancreas, an organ in most vertebrates and in humans and other mammals located in the abdomen. [1] The pancreas plays a role in the digestive and endocrine system , producing enzymes which aid the digestion process and the hormone insulin , which regulates blood sugar levels. [ 2 ]
Up to 90% [12] of PanNETs are nonsecretory or nonfunctional, in which there is no secretion, or the quantity or type of products, such as pancreatic polypeptide (PPoma), chromogranin A, and neurotensin, do not cause a clinical syndrome although blood levels may be elevated. [13] In total, 85% of PanNETs have an elevated blood marker. [2]
A pancreatic tumor is an abnormal growth in the pancreas. [1] In adults, almost 90% are pancreatic cancer and a few are benign. [1] Pancreatic tumors are rare in children. [1] Classification is based on cellular differentiation (ductal, acinar, neuroendocrine, other) and gross appearance (intraductal, cystic, solid). [1]
An ectopic pancreas is an anatomical abnormality in which pancreatic tissue has grown outside its normal location and without vascular or other anatomical connections to the pancreas. [2] It is a disease which is congenital [ 2 ] and is also known as heterotopic, accessory, or aberrant pancreas.
To confirm the diagnosis of gastrinoma a series of blood tests must be made. One of those tests is the serum gastrin level, which is the most reliable test for patients with gastrinoma. The normal levels of gastrin are 150 pg/mL ( > 72.15 pmol/L); therefore elevated levels of > 1000 pg/mL (> 480 pmol/L) would establish the diagnosis of ...
These blood tests are needed to diagnose insulinoma: [7] low glucose levels; elevated insulin levels; elevated C-peptide levels; If available, a proinsulin level might be useful, as well. Other blood tests may help rule out other conditions which can cause hypoglycemia.
