You’ve asked some very specific questions. Here are my thoughts:
1. Your last urine sample showed leukocytes, but from what I can tell, other infection markers weren't mentioned (like proteins, nitrites, or potentially red blood cells). It’s entirely possible those leukocytes came from vaginal contamination rather than the urinary tract itself. Because of that, determining how clean the sample actually was is vital.
It's quite common to find leukocytes or even bacteria (under a microscope) in urine when there isn't an actual urinary tract infection, but rather just "contamination" during collection. A urine culture is always more reliable than a quick dipstick test.
Since your last urine culture—if I understood correctly—was sterile three weeks ago, but this recent leukocyte finding is bothering you, you could start by re-checking the urine with a test strip. Just be extremely careful with how you collect the sample to avoid mixing it with vaginal discharge or skin contact. Since this is a quick and easy thing to do at your primary care doctor or gynecologist's office, there's really no reason not to double-check with a test strip first.
Definitely talk through these concerns and any next steps with your gynecologist or primary care physician.
2. Regarding CRP, infections in the lower urinary tract (the urethra and bladder) generally shouldn't cause a significant rise in CRP, unlike upper urinary tract infections. So, a CRP test won't really help confirm or rule out a lower urinary tract issue.
Best regards. 😉
Thanks for the reply... I will definitely head back to the lab to check my urine again. For context, on the day I had that urine culture three weeks ago, I also had a routine urinalysis which showed:
cloudy
proteins at 0.15 g/L (trace)
leukocyte esterase 70 (1+)
Leukocytes 7-8
quite a few squamous epithelial cells
some bacteria and amorphous urates...
...And then the culture came back sterile, yet during a routine checkup with my gynecologist, the test strip showed 4+ leukocytes in the urine.
Then I had my CRP checked yesterday, and it came back at 4.8...
Could you please tell me more about what these urine results mean? I read somewhere that leukocyte esterase indicates inflammation, essentially acting as a marker for it...
Also, one more question about the proteins being 0.15 g/L...
The urine wasn't my first morning sample... so I'm wondering—isn't that a slightly high amount of protein for urine that had only been sitting in the bladder for an hour?
I also read that proteinuria is diagnosed if daily values exceed 0.15 g/L...
Additionally, my blood pressure was recorded at 130/90 one day... then normal at 110/70 the next... but I was told to keep monitoring it. Does any of this mean anything to you?
Thanks for the help and the response.🙂
