In that case, I would suspect that the culture ordered from the lab repors only >10^5 CFU, and a lower level of E coli was present in the urinary tract -- enough to cause a positive nitrate, but not enough to be reported as "UTI" on the culture.
Nitrate in the urine indicates that there might be bacteria in your urinary tract or in your bladder. As such, nitrate tests are used to quickly assess whether a person may have a UTI (urinary tract infection) for example. If nitrate is found, no matter the hypothesized cause, other medical tests usually follow.
Yes, blood in the urine can be a symptom of a urinary tract infection (UTI).
Yes, blood in the urine can be a symptom of a urinary tract infection (UTI).
Yes, a UTI can result in the presence of blood in the urine.
Some of the bacteria known to cause urinary tract infections (UTI's) have an enzyme that change nitrate to nitrite. A positive nitrite test indicates that bacteria may be present in significant numbers in urine.reference:- http://www.medscape.com/viewarticle/410581- http://library.med.utah.edu/WebPath/TUTORIAL/URINE/URINE.html
A positive nitrite test in urine typically indicates the presence of bacteria that convert nitrate to nitrite, which is often associated with a urinary tract infection (UTI). This test is commonly part of a urinalysis and can suggest underlying infections, particularly from common pathogens like Escherichia coli. However, a positive result should be interpreted in conjunction with other clinical findings and tests for a definitive diagnosis.
Yes, a urinary tract infection (UTI) can cause blood in the urine. This is known as hematuria and can be a symptom of a UTI.
It's not unusual to have blood in the urine with UTI, but it doesn't not always occur.
