A simple assay method for added stable caesium in blood plasma
A new assay method was developed to determine added stable caesium (Cs) in blood plasma. The simple and inexpensive method is based on the competition between stable and radioactive Cs in binding to ammonium-iron(II)-hexacyanoferrate(III) (AFCF), followed by the precipitation of AFCF-bound Cs with plasma proteins, and the measurement of the radioactivity of the precipitate...
Keywords: ammonium-iron(II)-hexacyanoferrate(III), Blood, Caesium, Plasma, Prussian blue
01/2006 | Radiochimica Acta, Oldenbourg WissenschaftsverlagGlobal tests of haemostasis
Global tests of haemostasis represent several reaction steps in the physiologic process of clotting. The proportion of plasma or whole blood in the test mixture of a global test is significantly higher than in clotting factor tests...

01/2006 | Hämostaseologie, SchattauerThe role of ethylenediamine tetraacetic acid (EDTA) as in vitro anticoagulant for diagnostic purposes
Anticoagulants are used to prevent clot formation both in vitro and in vivo. In the specific field of in vitro diagnostics, anticoagulants are commonly added to collection tubes either to maintain blood in the fluid state for hematological testing or to obtain suitable plasma for coagulation and clinical chemistry analyses...

05/2007 | Clinical Chemical Laboratory Medicine, Walter de GruyterLong-term stability of endogenous B-type natriuretic peptide (BNP) and amino terminal proBNP (NT-proBNP) in frozen plasma samples
The aim of the present study was to assess the long-term stability of endogenous B-type natriuretic peptide (BNP) and amino terminal proBNP (NT-proBNP) in plasma samples stored at –20°C without addition of protease inhibitors (e.g., aprotinin)...

12/2004 | Clinical Chemical Laboratory Medicine, Walter de GruyterIs idiopathic recurrent calcium urolithiasis in males a cellular disease? Laboratory findings in plasma, urine and erythrocytes, emphasizing the absence and presence of stones, oxidative and mineral metabolism: an observational study
Background: The site of origin of idiopathic recurrent calcium urolithiasis (IRCU) – a disorder characterized by stones composed of calcium oxalate (CaOx) and/or calcium phosphate (CaPi) – is uncertain, because in urine such risk factors for stones as disturbed Ox, Ca and Pi are not regularly observed...
