Measure of Glomerular Filtration Rate in cats and dogs. The new assay from deltaDOT/RVC provides a highly accurate measure  of glomerular filtration rate (GFR). Because GFR is directly correlated  with functional renal mass, quantification of GFR is generally accepted as the best measure of renal function. The test is simple to carry out, safe and provides rapid results. The  quantitative nature of the results also means that repeated assays over  an animal’s lifetime enables disease progression to be accurately  monitored and the efficacy of treatment established. Prices start at £150 plus VAT for a single test, but discounts apply when  multiple tests are booked at the same time. Click HERE for more details and a test request form.
