A method is described based on a reaction that requires magnesium-ATP as a co-factor for the activity of hexokinase (HK), coupled with glucose 6-phosphate dehydrogenase (G6PDH). Glucose and NADP are converted to D-gluconolactone 6-phosphate and NADPH, respectively. The rate of increase in absorbance at 340 nm due to the formation of NADPH is proportional to(More)
BACKGROUND Troponin measurements are now central to the diagnosis of acute coronary syndromes and for the stratification of the severity of cardiac disease. Some laboratories have quickly adopted the new testing strategies, which include troponin measurement for the diagnosis of acute myocardial infarction, while others are still developing appropriate(More)
17-oxogenic steroids have been analysed by gas chromatography (GC) with capillary column and flame ionization detector. The best separation of steroid products was gained after ethyloxime-trimethylsilyl ether formation. The value of the GC method as a screening procedure for patients with suspected adrenal disease is illustrated in selected cases where the(More)
