What is the difference between urea and BUN
Urea is removed from the body through the kidneys, where it is filtered out of the blood and excreted in the urine.
Urea is one of the substances in urine, and urine is in your blood stream until the kidney extract the urine from your blood.
The normal range of urea in blood is typically between 7-20 mg/dL. Levels can vary slightly depending on the specific laboratory reference range used. Elevated urea levels may indicate kidney dysfunction or dehydration, while low levels could be seen in conditions like liver disease or malnutrition.
the blood plasma carries waste products, including urea.
Urea is formed in the liver from excess proteins. Therefore, the blood that travels from the liver to the kidney via the heart has relatively high levels (but not unsafe levels) of urea. It is filtered completely in the kidneys, and passes out in the urine. Consequently, blood in the renal veins (ie. leaving the kidneys) should have no urea, as it is a toxin which, if allowed to accumulate in the body, can poison us.
The normal range for microalbumin in urine is less than 30 mg/day. Elevated levels may indicate kidney damage or dysfunction. It is important to consult with a healthcare provider for proper evaluation and interpretation of test results.
Yes, the blood transports urea and other waste products so that they can be excreted.
Fibrinogen and Urea are not found in blood. Fibrinogen is a clotting factor found in plasma, while urea is a waste product of protein metabolism mostly excreted by kidneys. Glycogen, Glucose, and Albumin are all present in blood.

Kidney
A urea electrolyte test is a blood test that measures the levels of urea nitrogen, creatinine, and electrolytes such as sodium, potassium, and chloride in the blood. It helps evaluate kidney function and the body's electrolyte balance.
