When uric acid concentrations are elevated in a condition known as hyperuricemia, significant harmful health effects result. Blood uric acid levels above 7 mg/dl lead to the formation of monosodium urate (MSU) crystals. After sustained hyperuricemia, these MSU crystals deposit in tendons and joints to cause severe diseases including gout, kidney stones and several forms of kidney disease. Gout is the most prevalent inflammatory arthritis worldwide and frequent monitoring of uric acid levels is critical for disease management. In the case of kidney stones, approximately 5-10% of the 3.3 million Americans seeking medical care for kidney stones are due to elevated uric acid. High blood uric acid levels are also associated with a wide variety of diseases including hypertension, increased cardiovascular mortality, obesity and metabolic syndrome.
|Aliases:||urate, acid urate, monosodium urate|
|Optimum Collection Volume:||25 μL*|
|High consumption of alcohol beverages (particularly beer), fructose and diets high in purine-rich foods can alter Uric Acid levels.
Several drugs may alter Uric Acid levels (Moriwaki 2014).
|Assay Range:||0.07- 20 mg/dL|
Collect Saliva Samples
URIC ACID SALIVA COLLECTION CONSIDERATIONS
Better results begin with better saliva collection. This collection protocol features general considerations to maximize salivary Uric Acid analysis. Use this analyte specific collection protocol to plan your collection methodology and sampling schemes.
Add DNA Analysis to My Study
Considerations for adding Salivary DNA to analyte Studies:
You can combine salivary analytes with easy, accurate, and affordable genomic testing using Salimetrics SalivaLab and the same sample that you are already collecting – no specialized saliva collection devices or additional samples are required.
Don’t know what SNPs are right for you? The SalivaLab’s DNA team specializes in genetic testing services, we recommend you Request a DNA Consult (gratis) to learn more about common considerations such as # of samples, participant ethnicity, and IRB Approval.
