A Limited Sampling, Simple, and Useful Method for Determination of Glomerular Filtration Rate in Cats by Using a New Accurate HPLC Method to Measure Iohexol Plasmatic Concentrations

Table 3

Results of the accuracies of four simplified clearance Models A, B, C, and D in nonazotaemic cats (𝑛=35) and azotaemic cats (𝑛=15) when compared to GFR determination with 7-point reference clearance. There are no significant differences between the different methods neither at the 15%, the 30% levels nor at the 50% level.

Model	Nonazotaemic			Azotaemic
	Accuracy within			Accuracy within
	15%	30%	50%	15%	30%	50%
A	87	92	95	92	100	100
B	66	92	95	77	100	100
C	79	92	95	100	100	100
D	47	64	87	53	80	93
