I am a 51 yr old female and urine ph is 5 and specific gravity 1.003. crp is 4. i have ida .

What's the question?: This is what your urine specific gravity will normally be if you drink a few glasses of water beforehand. The only real reason to check urine ph is to see whether the specimen has been overgrown with alkali-producing bacteria. C-reactive protein reference-range values vary from lab to lab, the value fluctuates & means nothing in the absence of a history, no relevance to iron deficiency anemia.
