These are wastes filtered by the kidneys, and if they are elevated, they indicate presence of kidney disease. Low levels are not a cause for concern. when disorders listed by the first poster are present, these levels may be low, but other cryptogram will also be present that are more diagnostic than these. These low values, by themselves, do not mean you have any of those situation. You have nothing to worry in this area if these are your blood values.
