Saliva testing to

achieve a higher quality of care

Chronic kidney disease (CKD) affects as many as 10% of dogs and 35% of cats, and is the most common cause of mortality in cats over 5 years old (1)

Annual blood & urine work is usually recommended for animals over 7 years old; however, this is costly and invasive, leading many pet parents to forego testing, especially when there are no other clinical signs present.

Recent studies have shown that high blood urea, a common marker for CKD, is also present in the saliva (2-3). This is why sn biomedical is developing Kidney-Chek™ - a salivary urea test for companion animals. This is a simple, less invasive and more affordable option to screen for kidney disease in your animals. If Kidney-Chek™ shows up positive, it is then recommended that more detailed analysis of blood & urine take place, as high blood urea can also occur with other conditions, such as severe dehydration, gastrointestinal bleeding, or kidney stones (4).
