    This study was planned to determine the efficacies of single plasma sample methods (SPSMs) in indicating glomerular filtration rate (GFR) by taking two plasma sample method (TPSM) as reference in the determination of the GFR in cases with clinically stable renal transplantation. Ninety-six renal transplantation cases (33 female, 63 male; age interval 18-67, mean age 37.46 +/- A 11.81 years) progressing stably clinically and as laboratory, with minimum 6 months after transplantation were included in the study. The GFR values of the cases were measured with SPSM and TPSM. It is observed that all SPSMs have a strong correlation with TPSM. Highest correlation was observed between Groth&Aasted SPSM and TPSM GFR (intraclass correlation coefficient: 0.965). In the analyses performed by using the Bland-Altman analysis, GFR values calculated by all SPSMs were concordant to the TPSM which is the gold standard method in 95 % confidence interval (average +/- A 1.96 standard deviation) and were within the clinically acceptable limits. The narrowest concordance interval was obtained between Groth&Aasted Tc-99 m DTPA SPSM and Tc-99 m DTPA TPSM..Besides, we have obtained the minimum bias and precision value by the Groth&Aasted method. As a result; we can see that all the SPSMs give reliable results in measuring GFR in cases with renal transplantation; besides, we suggest Groth&Aasted method as the first option.
