Soon a simple saliva test may diagnose kidney diseases

Scientists have developed a new test, a simple saliva test using a dipstick, which could help diagnose kidney diseases.

Kidney disease can now be diagnosed with a simple saliva test, says a new study. The findings of the study will be presented at ASN Kidney Week 2016 November 15-20 at in Chicago, USA.

The test may also help in predicting patients’ risk of early death.

Simple and inexpensive tools for the diagnosis of kidney disease are lacking. Viviane Calice-Silva, MD, PhD (Pro-Kidney Foundation, Brazil) and her colleagues evaluated the diagnostic performance of a salivary urea nitrogen (SUN) dipstick, in Malawi, a low resource country in Africa.

Th saliva test uses the dipstick technique to diagnose kidney diseases.

“Our data suggest that SUN can improve the detection of kidney disease, increasing the awareness to this devastating complication,” said Dr Calice-Silva. “Also, higher awareness and detection of kidney disease in low resource settings may increase the number of patients who are diagnosed and referred, therefore providing appropriate treatment and improving outcomes.”
