Screening for primary aldosteronism using the newly developed IDS-iSYS® automated assay system
BACKGROUND The recommended approach to screening for primary aldosteronism (PA) in at-risk populations is to determine the ratio of aldosterone concentration (serum (SAC)/plasma (PAC)) to renin measured in plasma as activity (PRA) or concentration (DRC). However, lack of assay standardisation mandates the need for method-specific decision thresholds and clinical validation in the local populati...
متن کاملFour automated 25-OH total vitamin D immunoassays and commercial liquid chromatography tandem-mass spectrometry in Finnish population.
BACKGROUND Comparing four fully automated 25-OH-D immunoassays to a commercially available liquid chromatography-tandem mass spectrometry (LC-MS/MS) method with human serum samples from Finnish population. METHODS 400 samples were analyzed with the Liaison Total Vitamin D, the IDS-iSYS 25-Hydroxy Vitamin D, the ARCHITECT 25-OH Vitamin D, the ADVIA Centaur Vitamin D Total, and a commercially a...
متن کاملIDS iSYS automated intact procollagen-1-N-terminus pro-peptide assay: method evaluation and reference intervals in adults and children.
BACKGROUND We carried out a technical evaluation of the Immunodiagnostic Systems (IDS) automated intact procollagen-I N-terminus propeptide (PINP) assay on the iSYS platform, and established reference intervals for PINP in both adults and children. METHODS Assay imprecision, recovery and interference were studied. Serum and plasma values were compared, and PINP stability was assessed. Using 8...
متن کاملAssessment of vitamin C status.
Vitamin C is L-xyloascorbic acid (ascorbic acid, AA). Its first oxidation product is dehydroascorbic acid (dehydroAA) which also possesses vitamin C activity, possibly because of the ease with which many animal tissues can reduce it back to AA (Grimble & Hughes, 1967). AA and dehydroAA may be referred to as ‘total vitamin C’. T h e determination of AA, or of AA and dehydroAA, is central to all ...
متن کاملVitamin K Status in Chronic Kidney Disease
The purpose of this review is to summarize the research to date on vitamin K status in chronic kidney disease (CKD). This review includes a summary of the data available on vitamin K status in patients across the spectrum of CKD as well as the link between vitamin K deficiency in CKD and bone dynamics, including mineralization and demineralization, as well as ectopic mineralization. It also des...
