Is it possible for a mild bladder infection to not show up in a urinalysis?

Is it possible for a mild bladder infection to not show up in a urinalysis?

UA for infection: UA depends on several methods to detect infection, one is chemical reactions on the dipstick for leukocytes or protein. Another is the microscopic exam looking for cells and bugs, and the third would be culture or specific antigen tests. Overall sensitivity is high, but not 100% with these methods, but goes up as more are used to detect infection. ...Read more

Would a kidney infection show up in a urinalysis?

Would a kidney infection show up in a urinalysis?

Here are some...: The findings of urinalysis only suggest somewhere along urinary tract (from kidneys, ureters, bladder, to urethra) has inflammation, bleeding, bacteria, not specific to tell where is the exact origin, but high level protein indicates some kidney damage. Then the findings of UA should correlate closely with history and physical exam before giving a firm diagnosis. More? Ask doc timely. ...Read more

I had a urinalysis taken and pus cells count shows 2-4/hpf. I'm 24wks pregnant with cerclage placed. Is this enough pus cells to indicate infection?

I had a urinalysis taken and pus cells count shows 2-4/hpf. I'm 24wks pregnant with cerclage placed. Is this enough pus cells to indicate infection?

Sounds like no: In the US we do use the term pus cells in regards to a urinalysis. A UTI would be diagnosed by white blood cells, leucocyte esterase and/or nitrates. If there is any concern on a urinalysis though a urine culture can be ordered to confirm. ...Read more

Dipstick showed "+++" blood. Urinalysis showed "small" blood and no RBCs. How can it have blood but no rbcs? Doesn't blood = rbcs? CBC shows anemia

Dipstick showed "+++" blood. Urinalysis showed "small" blood and no RBCs.   How can it have blood but no rbcs? Doesn't blood = rbcs?  CBC shows anemia

Repeat Urinalysis: You are partially right. But RBCs can dissolve (Hemolysis) if the urine sample is not fresh when it is examined under the microscope. Therefore a fresh urine sample examined within 30 minutes of sampling should be sent to lab again and they should be cautioned that the test needs to be done right away and not let the urine sit in some corner of the office or in the lab before it is checked. ...Read more

In the ER recently for a bladder infection urinalysis shows presence of bilirubin. I'm taking Lamisil (terbinafine) could that be why?

In the ER recently for a bladder infection urinalysis shows presence of bilirubin. I'm taking Lamisil (terbinafine) could that be why?

Not likely: because urine bilirubin is sometimes detected by color alone, but always possible. Have your doctor repeat urinalysis after your cystitis clears, and ask if you should have a blood test for liver function tests. Lamisil (terbinafine) can affect liver, especially if you are taking other meds. ...Read more

Urinalysis clear, urine culture clear, ultrasound of bladder shows bladder wall thickening. is it infection or something else? Suffering from 6 years.

More information: Not enough information to give precise advice. Difficulty emptying bladder and thickening of bladder wall is consistent with a neurogenic bladder. What are your symptoms? What has your Urologist told you he believes the diagnosis is? You may want to get a second opinion. You can arrange a consultation on Health Tap. You would want copies of your studies to upload, along with your medical history ...Read more

Leukocyte esterase, ua my results were large. It also said "does not show any significant bacterial infection". Am i ok? Or do I need a 2nd opinion?

Leukocyte esterase, ua my results were large. It also said "does not show any significant bacterial infection".  Am i ok?  Or do I need a 2nd opinion?

Culture that urine. : A urinalysis (ua) cannot always identify the presence of bacteria or an infection. Although leukocytes can be present in the urine from other non-infectious causes, an infection should always be considered, and only a urine culture can diagnose or exclude an infection. ...Read more

How can a yeast infection cause my UA to show small traces of blood in urine.

How can a yeast infection cause my UA to show small traces of blood in urine.

Here are some...: Yeast alone almost unlikely cause UTI; usually it is a secondary cause like a patient with indwelling catheter, stent, or infected stones, etc. in the urinary tract. If there are no suspectable or identifiable underlying causes found, one has to think if urine contamination takes place in its collection. Besides, always interpret the test result with correlating with clinical profile. ...Read more

Recent abdo/pelvic MRI shows simple cyst left kidney. Could it cause: ua over 18mth high pyuria, occasional haematuria, proteinuria & infection?

Recent abdo/pelvic MRI shows simple cyst left kidney. Could it cause: ua over 18mth high pyuria, occasional haematuria, proteinuria & infection?

Simple cyst : Simple renal cysts are relatively common. If on MRI or contrast enhanced ct or even a good ultrasound, they meet the criteria for simple cyst, there's really no reason for concern. Solitary cysts of the kidney (of this nature) are not associated with the symptoms and findings you described. ...Read more

Trace hematuria, and proteinuria on some ua dipstick. Blood work shows normal kidney function. Ct w/contrast, xray kub, and us all normal. Ideas?

Benign glomerular dz: Hematuria and proteinuria suggests a glomerular cause ( kidney filter) since the urologic studies are negative. Kidney biopsy would be diagnostic but makes no sense since risk of progressive renal failure is very low as long as the urine protein is less than 500 mg a day. Diagnosis would include IgA nephropathy, thin basement membrane disease among others. As long as normal function u r ok. ...Read more

Will a urinary tract infection show up on dipstick urine test?

Mostly: Nitrite reagent in dipstick works for most gram negative organisms, but does show gram positive bacteria like enterococcus, staphlococcus or streptococcus etc.. Latter 2 are considered "skin" organisms but can be cause of utis in some, especially subjects on intermittent catheterization. Leucoocte esterase for wbcs in urine usually but, not always reliable. Urine culture is most reliable. ...Read more

Should u worry if ur urine tested positive for blood during a kidney infection but the dipstick showed no sign of infection sent to.Lab now?

Should u worry if ur urine tested positive for blood during a kidney infection but the dipstick showed no sign of infection sent to.Lab now?

See answer: If there was not an abnormal number of white cells (leukocytes) in the urine and the primary abnormal finding in the urinalysis was only the presence of blood, i would question the diagnosis of a kidney infection and look for other causes of your symptoms and microscopic blood (stone, incidental, etc). Urine culture results is what will or will not validate a uti. Ct scan imaging likely needed. ...Read more

?collection method ?: Most get pee at this age from having a kid pee in a cup.Unfortunately this squat pee is a vaginal washout mixed with pee and this can show leukocytes.I try to get moms to clean the area and get a labia spread (like a boy) pee if possible.If not a catheter specimen will bypass the washout effect.Kids with some stress or fever may show leukocytes in their pee, but it should not be a large amount ...Read more

Ua (Definition)

A ua is a urinalysis, or chemical and microscopic analysis of the urine. The standard urinalysis is performed with a dipstick test for ph, blood, protein, sugar, and ketones. In addition, a urinalysis usually includes a microscope examination to identify if the urine contains cells, "casts" (structures that indicate a problem originating in the kidney) or crystals (such as ...Read more
