What is difference between blood urea and blood urea nitrogen?
The conversion between both is that blood urea is approximately 2.14 times blood nitrogen bound to urea. Chemical formula of urea is ( NH2 )2 >C=O. i.e. Molecular weight of urea is 60 while nitrogen in it is 28 . 60/28 = 2.14 , so the conversion is blood urea nitrogen × 2.14 = blood urea , a calculative value .
What causes low urea levels?
A low urea value may be caused by a diet very low in protein, malnutrition, or severe liver damage. Drinking excessive amounts of liquid may cause overhydration and cause a low urea value. Women and children may have lower urea levels than men because of how their bodies break down protein.
