The serum glucose test, abbreviated as "BG" or "Glu", measures the liver's ability to produce glucose (gluconeogenesis); it is usually the last function to be lost in the setting of fulminant liver failure. [17]
A major source of transferrin secretion in the brain is the choroid plexus in the ventricular system. [15] The main role of transferrin is to deliver iron from absorption centers in the duodenum and white blood cell macrophages to all tissues. Transferrin plays a key role in areas where erythropoiesis and active cell division occur. [16]
Blood testing of the soluble transferrin receptor (sTfR) is used as a measure of functional iron status and the investigation of iron deficiency anemia. Ferritin , a routine investigation for anemia, is an acute-phase reactant , and may be elevated in states of inflammation , thereby falsely indicating that iron stores are adequate. [ 2 ]
Total iron-binding capacity (TIBC) or sometimes transferrin iron-binding capacity is a medical laboratory test that measures the blood's capacity to bind iron with transferrin. [1] Transferrin can bind two atoms of ferric iron (Fe 3+ ) with high affinity.
Transferrin receptor (TfR) is a carrier protein for transferrin. It is needed for the import of iron into cells and is regulated in response to intracellular iron concentration. It imports iron by internalizing the transferrin-iron complex through receptor-mediated endocytosis . [ 1 ]
Carbohydrate-deficient transferrin is elevated in the blood of people with heavy alcohol consumption but elevated levels can also be found in a number of medical conditions. The limitations of the assay depend upon the methodology of the test.
A test strip is a band/piece/strip of paper or other material used for biological testing. Specifically, test strip may refer to: Food testing strips; Glucose meter test strip; Lipolysis test strip; Urine test strip; Universal indicator pH test strips; It may also refer to: Teststrip, an art gallery in Auckland, New Zealand
Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).
