Estimating glomerular filtration rates in felines

Abstract

A method of estimating glomerular filtration rate of a feline can include measuring a blood sample of a feline for blood serum concentrations of pseudouridine and acetylthreonine, and optionally phenylacetylglutamine, and/or tryptophan, and also calculating a blood serum level product. The method can also include applying a feline factor as a multiple to the blood serum level product resulting in an estimated glomerular filtration rate. Calculating the blood serum level product can be based on a first weighted value based upon the blood serum concentration of pseudouridine, a second weighted value based upon the blood serum concentration of acetylthreonine,, an optional third weighted value based upon the blood serum concentration of phenylacetylglutamine, and an optional fourth weighted value based upon the blood serum concentration of tryptophan.
