What does nitrates in your urine indicate?
Normal urine contains chemicals called nitrates. If bacteria enter the urinary tract, nitrates can turn into different, similarly named chemicals called nitrites. Nitrites in urine may be a sign of a urinary tract infection (UTI). UTIs are one of the most common types of infections, especially in women.
What bacteria causes nitrates in urine?
A positive result on the nitrite test is highly specific for UTI, typically because of urease-splitting organisms, such as Proteus species and, occasionally, E coli; however, it is very insensitive as a screening tool, as only 25% of patients with UTI have a positive nitrite test result.
What is a positive UA for UTI?
We define a urinalysis as positive if it contains nitrites, leukocyte esterase, bacteria, or >10 white blood cells per high-power field. We define positive urine culture as >100 000 colony-forming units of a single species (voided) or >100 colony-forming units of a single species (catheterized) [8].
What antibiotic is used for nitrates in urine?
Nitrofurantoin is an oral antibiotic that is used in the treatment and prevention of lower UTIs.
What is the most common antibiotic for a UTI?
Drugs commonly recommended for simple UTIs include:
- Trimethoprim/sulfamethoxazole (Bactrim, Septra, others)
- Fosfomycin (Monurol)
- Nitrofurantoin (Macrodantin, Macrobid)
- Cephalexin (Keflex)
- Ceftriaxone.
Does cranberry juice help with UTI?
Cranberry juice and cranberry juice supplements are perhaps the most popular natural treatments for UTIs. Cranberries contain compounds such as phenolic acids and flavonoids, which may help treat and prevent UTIs.
Does cranberry juice cure a UTI?
If you do want to try cranberry juice to prevent UTIs, it’s better to drink pure, unsweetened cranberry juice (rather than cranberry juice cocktail). Drinking cranberry juice cocktail doesn’t seem to prevent UTIs better than drinking any other fruit juice. There is no proof that cranberry can cure a UTI.
