1. What other tests are used with urea to check how my kidneys are functioning?
Urea and creatinine are often the first tests that are used to check how well the kidneys are able to filter waste products from your blood. Your doctor may also request electrolyte tests such as sodium and potassium, or calcium to help understand how your kidneys are functioning.
2. How does urea change with age?
Urea levels increase with age. Urea levels in very young babies are about 2/3 of the levels found in healthy young adults, while levels in adults over 60 years of age are slightly higher than younger adults. Levels are also slightly higher in men than women.
3. What happens to urea in pregnancy?
Urea levels are normally slightly lower in pregnancy, especially in the last few months when the fetus is using large amounts of protein for growth.
