Hi--I found this on a blog (I know I said don't trust a blog, but I already knew the answer, he explained it very well, and I could back it up with hits from legitimate websites). He also had some other posts regarding ACE vs Ace, followup vs follow up, etc.

Another confusion regarding using nitrate versus nitrite comes to my notice. I will just try to explain. Hope this will help you.
NITRATE is a salt of nitric acid. Nitrate generally refers to a class of drugs, in the form of isosorbide mononitrate and isosorbide dinitrate, given for angina pectoris (chest pain). It is never to be written in urinalysis or any lab test concerning urinary tract infection.
NITRITE is a salt of nitrous acid, which is a laboratory data for determining urinary tract infection or UTI. A positive nitrite test indicates that bacteria may be present in significant numbers in urine. This is always meant and said in the urinalysis portion of the laboratory test.
BOTTOM LINE
1. Nitrite--the “i” corresponds with UTI. So, for UTI and urinalysis, it is always nitrite.
2. Nitrate--a drug for angina pectoris, where "a" corresponds to angina.
You can also google "nitrites urinalysis" (no quotes) and "nitrates angina" (again, no quotes) and get hits from legitimate websites like WebMD.com which will back up the blog information.
Hope this helps!
