Serum cystatin C has been suggested as a new marker of GFR. For the introduction of this marker into clinical use a rapid and automated method is required. We have developed and validated an assay for serum cystatin C using latex particle-enhanced immunoturbidimetry. Intra- and inter-assay precision were < 3% and < 5% across the assay range.

Placental teratomas are very rare, and the features that distinguish them on sonography and allow their differentiation from other placental tumors have not been fully described. Prenatal recognition of this tumor is prognostically useful because, unlike other neoplasms, placental teratoma is benign and almost never associated with congenital deformities in(More)
AIM To establish a reference range in the paediatric population for the new glomerular filtration rate (GFR) marker, cystatin C, and to compare it with that of creatinine. METHODS Cystatin C and creatinine were measured by particle enhanced nephelometric immunoassay (PENIA) and fixed interval Jaff¿e methods, respectively, in 291 children aged 1 day to 17(More)
OBJECTIVES Nonalcoholic fatty liver disease (NAFLD) is commonly associated with type 2 diabetes mellitus (DM) though its prevalence is not well studied. We conducted a prospective study of prevalence and risk factors of NAFLD in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS 204 type 2 DM patients attending an out-patient diabetic clinic(More)
OBJECTIVE The aim of this study was to investigate the inter-relationship between urinary excretion of alpha-1-microglobulin (A1M), retinol-binding protein (RBP) and albumin in term and premature neonates, with urine collected into cotton wool balls and extracted by a novel method. SUBJECTS AND METHODS Sixty-four infants were studied on the first day of(More)
OBJECTIVE The objective of this presentation is to provide an overview of sonographic manifestations of Budd-Chiari syndrome (BCS). METHODS Patients were scanned with ultrasound systems using mainly a 2- to 5-MHz curvilinear transducer and in some patients a 5- to 12-MHz linear transducer. The patients were asked to fast from the previous night or for at(More)
The measurement of urine albumin now has a well-established role in the monitoring of patients with diabetes mellitus. We have developed a particle-enhanced immunoturbidimetric inhibition assay for urine albumin on the Dade aca analyzer. The inhibition approach removes any of the potential antigen excess difficulties that could be expected from the wide(More)
BACKGROUND The affinity and specificity of protein reabsorption by proximal tubular cells have been investigated using techniques for monitoring endocytosis, demonstrating a high capacity but low affinity process. It is not known whether uptake is through binding to a single binding site/receptor with differing affinities, or if there are several classes of(More)
