Datasheet:

Urea (BUN) is the main product of human protein metabolism. Urea constitutes the majority of non-

protein nitrogen in blood. Blood urea nitrogen is one of the main indexes of renal function. This kit use

indophenol blue colorimetric method to test NH₃-N product by urease hydrolysis. The concentration of

indophenol is proportional to urea nitrogen concentration.

Reagents and Equipment Required but Not Provided:

Spectrophotometer, balance, cryogenic centrifuge, 1 mL glass cuvette, mortar/homogenizer, constant

temperature water bath pot.
