Introduction Since the first publications on cardiac troponin (cTn) in the 1970s, around 20.000 scientific reports on this powerful biomarker of myocardial injury have been published. Over time, cTn assays improved their analytical performance and became the designated biomarker for ruling out or ruling in acute...

Accurate estimation of in vivo blood glucose concentration is potentially compromised by in vitro glycolysis, the temperature- and time-dependent enzymatic metabolism of glucose by blood cells after blood is removed from the body.  For more than 40 years it was recommended that in order to avoid the potential problem ...

In health, plasma total calcium concentration is maintained within the approximate reference interval: 2.20-2.60 mmol/L (8.8-10.4 mg/dL), so that hypercalcemia (increased blood calcium) is defined as plasma total calcium greater than 2.60 mmol/L (10.4 mg/dL). The two most common causes of hypercalcemia are malignant...
