In Australia, we always see ‘urea’ referred to in results how do I enter that into the software?

Is Urea the same as Uric Acid?

The short answer is urea is the same as Blood Urea Nitrogen or BUN, which is a biomarker in the software. Add the "Urea" result into the BUN section.

No, Urea is not the same as Uric Acid!

Here's some background info on Urea and Uric Acid

Urea is formed in the liver and is the final product in protein catabolism, along with CO2. It is formed almost entirely by the liver from both protein metabolism and protein digestion. We can measure the amount of urea in the blood and that is what the "Urea" biomarker on your lab results refers to. In the US, Urea on a blood test is called BUN or Blood Urea Nitrogen. It's the same thing as Urea. Both reflect the ratio between the production and clearance of urea. The amount of urea excreted as Urea or BUN varies with the amount of dietary protein intake. Increased Urea or BUN may be due to increased production of urea by the liver or decreased excretion by the kidney.

Uric acid is something completely different. Uric acid is produced as an end product of purine, nucleic acid, and nucleoprotein metabolism. Levels represent the end product of protein utilization and deamination in the liver. The kidneys store and excrete about 2/3rds of the uric acid produced daily, making it an indirect marker of renal function as well. The remaining 1/3rd is excreted in the stool. Uric acid is the end-product of xanthine oxidase activation and reduced tissue oxygenation will induce its production. An over-production of uric acid occurs in conditions of excessive breakdown and catabolism of nucleic acids, increased destruction of cells, and an inability to adequately excrete uric acid.
