Weekly biological variation of serum biochemistry analytes and fibroblast growth factor 23 in healthy cats and cats with chronic kidney disease.
Objective: The objective of the study was to determine the biological variation of select serum biochemistry analytes and fibroblast growth factor 23 in both clinically healthy cats and cats with chronic kidney disease.
Methods: Eleven healthy cats and seven cats with chronic kidney disease International Renal Interest Society Stages 2 and 3 were included. Sera were collected once a week for 6 weeks and frozen for batch analysis in duplicate. Blood urea nitrogen, total carbon dioxide, creatinine, magnesium, phosphate, potassium, symmetric dimethylarginine, total calcium and fibroblast growth factor 23 were measured. Restricted maximum likelihood estimations were used to determine the coefficients of variation, and the inverse indices of individuality and reference change values were calculated.
Results: No analytes had low individuality. Biochemistry analytes had either intermediate or high individuality in healthy cats and cats with chronic kidney disease. Fibroblast growth factor 23 had high individuality in healthy cats and cats with chronic kidney disease. The reference change values for analytes was overall similar between healthy cats and cats with chronic kidney disease, including the reference change values for creatinine (19.8% and 18.4%, respectively), symmetric dimethylarginine (35.2% and 35.5%, respectively) and fibroblast growth factor 23 (60.0% and 75.5%, respectively).
Clinical significance: Biological variation estimates for each analyte were similar between healthy cats and those with chronic kidney disease. All analytes had intermediate to high individuality in cats with chronic kidney disease; thus, determining a cat's baseline and applying the reference change values to subsequent measurements may enhance the detection of clinically relevant changes that could be missed when using population-based reference intervals.
期刊介绍：
Journal of Small Animal Practice (JSAP) is a monthly peer-reviewed publication integrating clinical research papers and case reports from international sources, covering all aspects of medicine and surgery relating to dogs, cats and other small animals. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. JSAP publishes high quality original articles, as well as other scientific and educational information. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of small animal medicine and surgery.
In addition to original articles, JSAP will publish invited editorials (relating to a manuscript in the same issue or a topic of current interest), review articles, which provide in-depth discussion of important clinical issues, and other scientific and educational information from around the world.
The final decision on publication of a manuscript rests with the Editorial Board and ultimately with the Editor. All papers, regardless of type, represent the opinion of the authors and not necessarily that of the Editor, the Association or the Publisher.
The Journal of Small Animal Practice is published on behalf of the British Small Animal Veterinary Association and is also the official scientific journal of the World Small Animal Veterinary Association
