I think a urologist would better answer my question, however... These are the results of my urine cultures through one local hospital. I know that the last 3 results were "clean catch" tests. Which of these indicate true infection and which are most likely "contamination"?
7/6/11 Escherichia coli
2/22/13, Enterococcus species, and Staphylococcus species (presumptive ID)
1/15/14 Corynebacterium species, Non-hemolytic Streptococcus, Staphylococcus species, Lactobacillus species (Presumptive ID)
1/22/14 Gram Positive flora...
1/28/14 Mixed Gram Positive flora...
