IDEXX kidney health solutions

Kidney function is a vital window into your patient's overall health, but you can't manage what you can't see. Our suite of tests and technologies sheds light on your patient's kidney health, helping you intervene earlier and treat with greater confidence.

Diagnostic solutions

The tools you need to assess kidney function, injury, and management of treatment—resulting in better outcomes throughout the life of your patients.

Deeper insights, earlier.

IDEXX SDMA testing

Whether in-house or at the reference lab, SDMA can keep you ahead of the curve when it comes to declining kidney function—detecting mild to moderate loss that creatinine misses.1–3

Including SDMA in your chemistry profile adds substantial value for both the sick and well patient in the early detection of primary renal diseases as well as the reflection of impact on renal health caused by concurrent diseases.2–14

IDEXX Cystatin B Test

With the 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. Now with the IDEXX Cystatin B Test, a simple urine-based test, you can uncover kidney injury when clinical signs may or may not be apparent and gain additional insights beyond the changes in functional markers such as SDMA and creatinine.

Stay ahead of phosphorus overload.


The IDEXX FGF-23 Test is an entirely new method to manage and monitor phosphorus overload in cats with chronic kidney disease (CKD) and is now included in the IRIS Treatment Recommendations for CKD in Cats.15

The IDEXX FGF-23 Test can enable confident treatment recommendations, such as diet changes, and it can offer early detection of metabolic bone disease in cats with IRIS CKD Stages 1 and 2.16,17

Complete urinalysis and UPC

A complete urinalysis and urine protein:creatinine (UPC) ratio contribute to a deeper view of kidney health. Looking at urine specific gravity (USG) also provides needed context regarding hydration status as well as kidney function when interpreted alongside the functional kidney biomarkers. In addition, including a UPC ratio may aid in the diagnosis and treatment of CKD. Complete urine testing is integral to confidently assess your patients' kidney health status.

Tools and technologies

From patient-specific insights to individualised baselines, our ever-evolving suite of tools and technologies gives you everything you need to make a confident decision—right alongside your results (both in-house and reference lab).

Every patient is unique. So is their baseline.

VetConnect PLUS

A single test result, while important, is limited in value with nothing to compare it to. This makes routine monitoring of kidney health essential for patients whether they are sick, well, juvenile, or geriatric. With VetConnect PLUS, you can establish an individualised baseline for every patient, spot trends, and review patient history all in one place.

You can also access differential diagnoses in VetConnect PLUS to help interpret patient results, along with guidance from the latest industry protocols, research, and publications.
