Journal of Chromatography B: Biomedical Sciences and Applications, 1984
A simple, rapid and micro high-performance liquid chromatographic method was developed for separate or simultaneous determination of p-aminohippuric acid and iothalamate in plasma and urine using p-aminobenzoic acid as an internal standard. The method involved deproteinizing samples with two volumes of acetonitrile followed by injection of 5 ...

Traditionally, creatinine clearance is used as an estimation of the glomerular filtration rate (GFR) because of its relative ease and low cost. Errors in collection limit its usefulness. Estimation of GFR using 99m Tc diethylene-triamine pentaacetic acid (Tc-DTPA) by direct scintigraphic determination of fractional radionuclide accumulation within ...

A simple high-performance liquid chromatographic (HPLC) method was developed for the simultaneous determination of iohexol, iothalamate, p-aminohippuric acid (PAH) and n-acetyl-p-aminohippuric acid (n-acetyl-PAH) in human plasma and urine. A C(18) column at a flow rate of 1 ml/min with an aqueous mobile phase of trifluoroacetic acid (0.1% TFA in ...

AbstractA high‐performance liquid chromatographic (HPLC) assay method has been developed for the quantitative determination of iothalamate and p‐aminohippuric acid (PAH) concentrations in serum and urine samples in the male rat. Glomerular filtration rate (GFR) was measured as clearance of iothalamate, while effective renal blood flow (ERBF) was ...

Iothalamate (IOT) clearance and p-aminohippuric acid (PAH) clearance are used for estimation of glomerular filtration rate (GFR) and effective renal plasma flow (ERPF). A simple and rapid method is described for simultaneous determination of IOT and PAH in the same chromatogram in the serum and urine of humans. The mobile phase consisted of methanol-50
