Final answer:
An elevated blood urea level indicates serious impairment of renal function. Renal uremia is a condition associated with kidney disorders characterized by an increase in blood urea level above 300 mg/dl. Renal failure can lead to abnormal fluid levels, deranged acid levels, abnormal levels of potassium, calcium, phosphate, hematuria, and anemia.
Step-by-step explanation:
An elevated blood urea level indicates serious impairment of renal function. Renal uremia, which is characterized by an increase in blood urea level above 300 mg/dl, is a condition associated with kidney disorders. Biochemically, it is typically detected by an elevated serum creatinine. Renal failure, which is described as a decrease in the glomerular filtration rate, can lead to abnormal fluid levels, deranged acid levels, abnormal levels of potassium, calcium, phosphate, hematuria, and anemia.
