Urine Nitrite is a measure of the amount of nitrite in the urine. The presence of nitrite in the urine may indicate a urinary tract infection.

iollo markers that associate with Nitrite

Arginine

Arginine is the precursor for nitric oxide synthesis. Nitric oxide can be oxidized to form nitrite. Higher arginine availability may increase nitric oxide production and nitrite levels.

Asymmetric dimethylarginine

ADMA is an endogenous inhibitor of nitric oxide synthase. Higher ADMA levels can suppress nitric oxide production from arginine, potentially leading to reduced nitrite levels.

Ornithine

Ornithine and citrulline can be interconverted in the urea cycle. Changes in ornithine levels may impact citrulline and downstream nitric oxide and nitrite production.
