title: The estimation of nitrate and nitrite in saliva and urine.
abstract: A method for the estimation of nitrate and nitrite is described in which nitrate is converted to nitrite by Klebsiella pneumoniae (UNF 9232) and nitrite is estimated by the Griess reaction before and after incubation. The method is suitable for the estimation of 1-25 nmol of each ion in body fluids, many samples can be handled simultaneously, and special apparatus is not required.
