IDEXX Cystatin B Test
A first-of-its-kind veterinary test to detect kidney injury.
With the IDEXX Cystatin B Test, IDEXX’s kidney health suite is more comprehensive than ever. Never before have veterinarians been able to detect active or acute injury to the kidneys with a kidney injury marker. Now with the IDEXX Cystatin B Test, a simple, urine-based test for unwell patients, you can uncover renal tubular injury when clinical signs may or may not be apparent.
Can a kidney tell you if it’s injured? It can now.
If you don’t know an injury has occurred, how can you treat for it? The IDEXX Cystatin B Test helps uncover subclinical ongoing (active) injury to the kidney that may or may not affect its function.
When can your practice get its paws on the IDEXX Cystatin B Test?
In 2024, the IDEXX Cystatin B Test will be added to a number of IDEXX Reference Laboratories panels and profiles that include urinalysis. Plus, it will be available as a standalone and add-on test.

FAQs
Cystatin B is a member of the cystatin family of cysteine proteases. It is a small intracellular protein that is released into the urine when epithelial cells are damaged or die.
Kidney disease is a pathological state or condition where the function of the kidneys has been permanently altered. A patient is diagnosed with kidney disease when the kidneys’ ability to do one or all of their primary functions is compromised. Kidney injury refers to damage to the kidneys that may or may not affect the function of the kidneys.
Cystatin B is an intracellular protein that is released into the urine following damage to renal tubular epithelial cells. Cystatin B can be used to identify kidney injury but does not evaluate kidney function. Other renal biomarkers, such as SDMA, creatinine, and BUN, correlate with glomerular filtration rate (GFR) and are used to evaluate kidney function.
Store 10 days at 2-8° C. Do not freeze.
