Estimation of Glomerular Filtration Rate by Use of Beta-Trace Protein

Estimation of glomerular filtration rate by use of beta-trace protein.

Improved Glomerular Filtration Rate Estimation by an Artificial Neural Network

BACKGROUND Accurate evaluation of glomerular filtration rates (GFRs) is of critical importance in clinical practice. A previous study showed that models based on artificial neural networks (ANNs) could achieve a better performance than traditional equations. However, large-sample cross-sectional surveys have not resolved questions about ANN performance. METHODS A total of 1,180 patients that ...

Assessment of serum beta-trace protein (BTP) measurement in the prediction of glomerular filtration rate. Comparison with serum cystatin C.

Serum BTP measurement is sometimes believed to be an alternative marker of glomerular filtration rate (GFR) assessment. The aim of the present work was to investigate the correlation between creatinine, cystatin C, and BTP values in sera and to compare the diagnostic efficacy for serum BTP and cystatin C with the glomerular filtration rate estimate. 25 individuals were tested. GFR was estimated...

Measurement of glomerular filtration rate with Tc-99m DTPA [Persian]

Abstract is NOT available

Beta-trace protein is not better than cystatin C as an indicator of reduced glomerular filtration rate.

To the Editor: Recent studies suggest that serum cystatin C [reviewed in Refs. (1, 2)] and -trace protein (3, 4) identify reductions in glomerular filtration rate (GFR) better than creatinine does. Woitas et al. (5 ) compared for the first time the diagnostic performance of cystatin C, -trace protein, 2microglobulin, and creatinine in relation to inulin clearance. They noted that we reported a ...
