My urine culture shows E. coli resistant to many drugs, including ciprofloxacin and levofloxacin. However, in a different, well established lab (operating since 1965), the same test done three times shows the bacteria are susceptible to these drugs. Which lab results should I trust? How is it possible to get two different results for the same bacteria? The prior lab used automated sensitivity testing, while the other lab reports in vitro DST results

Different labs use different methods, cut offs. Automated may detect low resistance. Follow report from trusted lab. Repeat Urine Culture (same lab) if unsure. Consult doctor before antibiotic change.

A few days after having unprotected sex, I started experiencing a burning sensation while urinating. My partner is also having similar issues, including kidney pain and some abnormal values in her blood report, such as a high pH level. Based on these symptoms, I suspect it might be a urinary tract infection for both of us.

Hello, I am attaching my urine routine test report. Yesterday I had whitish urine with small white strings and a little burning sensation. I told my doctor friend about this, and he asked me to do a routine urine exam but said there is nothing significant in the test. Please help.
