Does hemolysis affect ionized calcium
Did you know?
Does hemolysis affect ionized calcium? Hemolysis will falsely lower ionized calcium values. Once collected, the pH of a blood sample may decrease from cell metabolism or increase due to loss of carbon dioxide if the specimen is exposed to air. Ionized calcium values change inversely to pH. The magnitude of change … See more Two analytes greatly impacted by hemolysis are potassium and lactate dehydrogenase, in which their concentrations in erythrocytes are more than 20 times and … See more As previously reported, in vitro hemolysis is known to negatively interfere with sodium due to a diluting effect (13,14), as the intracellular concentration of sodium is significantly lower than the concentration in serum or plasma. See more Hemolysis is a natural process where the body destroys older RBCs that no longer work efficiently. However, some conditions, medications, and toxins may cause RBCs to break down prematurely. When this occurs, … See more Hemolysis may falsely increase the following analytes: AST, alanine transaminase (ALT), LDH, total bilirubin, glucose, calcium, phosphorus, total protein, albumin, … See more WebNov 28, 2005 · Hypercalcemia is defined as a total serum calcium concentration >10.5 mEq/L (or an elevation in ionized calcium >4.8 mg/dL).
