Know your Urine Nitrite. Know your health.
Test your Urine Nitrite and 100+ other biomarkers in a single blood draw.
Nitrites are not normally present in urine. Many of the bacteria that cause urinary tract infections convert nitrates (normally in urine) into nitrites, so a positive result strongly suggests a bacterial UTI. A negative result does not fully rule out infection, since not all bacteria produce nitrites and the urine must sit in the bladder long enough for the conversion to occur. Nitrite is interpreted alongside leukocyte esterase and the microscopic exam to assess for infection.
Urine Nitrite isn't sold on its own. It comes in a routine urinalysis, about $45. A fuller workup adds Vitamin D ($75), hs-CRP ($69), ApoB ($50), and ApoA1 ($50). You can test Urine Nitrite and 100 other biomarkers for $190 as part of an Empirical membership.
Empirical is FSA/HSA eligible, so you can pay with pre-tax dollars. Fast for 8-12 hours beforehand for the most accurate lipid and metabolic results, and expect results in days rather than weeks.
Urine Nitrite is drawn at 2,200+ Quest and BioReference patient service centers across the US, so there's usually one within a short drive. Browse the full directory to find the one closest to you.
