What is it indicated for?

IL Test™ Urea Nitrogen is an in vitro diagnostic test for use with Instrumentation Laboratory’s line of clinical chemistry systems in the quantitative determination of urea and urea nitrogen in human serum, plasma or urine by enzyme-coupled urease/GLDH methodology. Increases in serum urea nitrogen (urea) can be a result of kidney dysfunction or urinary tract obstruction'.
