How to interpret urine culture/ urinalysis?

How to interpret urine culture/ urinalysis?

Normal ranges: The urinalysis report should contain a normal reference range for each item tested. If there are any tests that fall out of that range, it will be flagged as abnormal. As far as a urine culture is concerned, if the specimen was collected correctly, any bacteria found would be considered abnormal and should probably be treated, especially if you have symptoms of a urinary tract infection.

If my urinalysis was normal can a urine culture still show I have a uti?

Yes: Because of this relative insensitivity of dipstick urinalysis, the absence of leukocyte esterase (let) does not rule out urinary tract infection (uti). Similarly, and more common, a positive let on dipstick does not always indicate the presence of a uti. A urine culture should generally be done when symptoms suggest the presence of a UTI regardless of the urinalysis results.

Can a positive urine culture with group b strep, but normal urinalysis confirm a UTI? Or likely to not be a UTI?

Can a positive urine culture with group b strep, but normal urinalysis confirm a UTI? Or likely to not be a UTI?

Confirm a UTI: Group B strep is usually a gut bacteria. If there are symptoms such as burning on urination foul-smelling urine for the positive culture it is most likely a urinary tract infection. Urinalysis probably would show a positive leukocyte esterase test. The culture is usually the goal stand it if it is greater than 100, 000 colonies.

Hwbc & lrbc in a urinalysis and blood? I did have a UTI at the time. My urine culture was normal. Should I be worried?

Incomplete info: All lab results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the position to do that. It would be helpful to look at the actual lab results. Blood in urine is something to be concerned about and you should consult your doctor.

During a routine checkup, my urinalysis showed elevated wbc, negative urine culture, no symptoms. What may the cause be?

Various Causes.: Having WBCs in your urine without symptoms is described as sterile pyuria. This depends also on how many WBCs are present. This can be due to many conditions including contamination, various infections including STIs, inflammatory conditions etc. I would discuss with your provider and have them review your full urinalysis to see if there are any other abnormalities present and review your history.

Went for a microscopic urinalysis results - mucus present and urine culture- organisms recovered in low numbers. What do these mean? Infection?

Unlikely: Urine screening tests also look for other markers of infection like nitrite and leukocyte enzymes. If those were negative and urine culture had low number of bacteria, it is not likely to be infection.

Burning feeling all day after bowel movement and ejaculation? Urinalysis and Urine Culture Test clear. Issues from 6 years after varicolectomy. Solution

Diagnosis first: In such a situation, one can ask for a Voiding Cystourethrogram (VCUG) and for an Abdominal + Bladder ultrasound scan. The VCUG may show that the urine is flowing the correct way during urination, or if there is a problem, it may show urine going into an unusual direction or location. The urologist and radiologist can help figure this one out.

Tiny sample of urine is spread on a bacterial growth culture medium, e.G agar & placed in an incubator to grow. Positive urine cultures demonstrate colonies of bacteria which can then be identified.
