Pet parents often forgo screening testing due to cost and a lack of perceived value if the animal shows no clinical signs of disease. 

Recent studies have shown that saliva urea correlates with blood urea in both acute and chronic kidney disease and can be used to screen for azotemia.

Kidney-Chek™ measures salivary urea to catch azotemia in both cats and dogs!

​

Kidney-Chek™ is a clinically proven*, patent pending salivary urea test designed to detect azotemia in companion animals.

It is a simple, non-invasive, and more affordable option to screen for kidney issues between regular veterinary exams.

Kidney-Chek™ interpretation

In dogs, with normal clinical presentation:

In cats, with normal clinical presentation:

Note: in cases where renal insufficiency is suspected clinically, no strip result can rule out azotemia and blood testing is recommended.

High urea can be a result of many conditions, including:

• Chronic Kidney Disease (CKD)

• Acute renal toxicity - i.e. from ingesting ethylene glycol (antifreeze) or fertilizer

• Gastrointestinal bleeding - i.e. from ulceration due to chronic NSAID use

• Acute kidney injury

• Severe dehydration

• Urinary tract obstruction

Kidney-Chek™ was evaluated as a rapid, non-invasive method to screen for azotemia. The test is a semi-quantitative method that assesses 7 levels of saliva urea concentration, and indirectly serum urea, from < 3 to > 17 mmol/L. Ninety-two dogs (14 azotemic) and 56 cats (16 azotemic) were enrolled. Saliva urea was compared to serum urea and the sensitivity and specificity calculated for detecting serum urea above the upper limit of the reference interval.

It is recommended that Kidney-Chek™ be used as an exclusion test with additional investigation for dogs with a test strip reading of 9-11 mmol/L and higher, and for cats with a test strip reading of 12-14 mmol/L and higher.
