Salivary Bioscience News

New Uric Acid Assay Kit from Salimetrics Advances Metabolic & Obesity Research Through Non-Invasive Saliva Testing that Correlates with Blood Uric Acid Levels

Uric Acid in Saliva

(November 03, 2015)

Salimetrics’ innovative Salivary Uric Acid Enzymatic Assay facilitates non-invasive monitoring of Uric Acid levels for participant-centric research studies. Saliva as a biospecimen requires no needles, no phlebotomist, and is rapid, easy and economical.

Metabolic syndrome is becoming an ever more prevalent, chronic disease associated with many serious health issues (e.g., abdominal obesity, glucose intolerance, insulin resistance, dyslipidaemia and hypertension). A longitudinal epidemiological study (NHANES 1999-2002), demonstrated a strong link between serum uric acid and metabolic syndrome (3). The research indicates that people who suffer from metabolic syndrome may be at an increased risk of developing type II diabetes and coronary heart disease.

With the newly introduced Salimetrics Salivary Uric Acid Assay Kit, researchers will be able to elucidate the complex mechanisms and pathways related to uric acid’s influences on metabolic syndrome and its risk factors using only a drop of saliva. A strong uric acid serum to saliva correlation of 0.95 to 0.71 has been previously reported (1, 2), which ensures that the measurement of salivary uric acid is an effective biomarker. Decades of research shows that uric acid continues to have strong prognostic potential as an indicator of metabolic syndrome development (3-7) and current research has linked uric acid to oxidative stress, hypertension, and abdominal obesity (8-10).

Salimetrics provides the tools necessary to enable scientific research within this multi-disciplinary field, to further define metabolic syndrome and characterize the multitude of pathways involved. Salivary biomarkers offer a unique advantage over traditional blood sampling by providing researchers with additional opportunities to increase statistical power by maintaining strong participant participation and retention at lower operational costs. Additionally, the use of salivary biomarkers can be pivotal in developing effective clinical diagnostics and pharmaceutical treatments to better the lives of patients.
