I have a high serum urea level 10.1mmol/l. What does this mean?

The blood urea nitrogen (BUN) is one of the chemicals measured in the blood that can reflect kidney function, but also can reflect other things such as bleeding into the gastrointestinal tract, high protein diet, and dehydration.  A normal BUN is between 2.5 and 7.1 millimole per liter (mmole/L) and hence your test is mildly elevated.  I am unable to interpret your test without seeing you and performing a complete history and physical examination.  I suggest that you discuss this with your physician.
