Blood in the urine (called hematuria) is abnormal. There are various etiologies of microscopic (seen only under the microscope) and/or gross hematuria (seen with the nake eye) including benign essential hematuria , urinary tract infection, stone, or possible malignancy. The most common cause identified for asymptomatic microscopic hematuria is “benign essential hematuria”. This means that the kidneys are simply losing some red blood cells into the urinary tract. Urinary tract infection can cause irritation in the bladder causing microscopic hematuria . Kidney cancer and/or bladder cancer can also present as microscopic blood or gross blood. Smoking dramatically increases the risk of developing a tumor in the urinary tract. A stone in the urinary tract can rub the inside of the urinary tract resulting in microscopic or gross hematuria. Evaluation for the possibility of all of these etiologies should be done. However, the only way to diagnose benign essential hematuria is to prove there is no significant stone, tumor, or urinary tract infection. Urine cytology, CT of the abdomen and pelvis or intravenous pyelogram or renal ultrasound, and cystoscopy are the tests to determine the diagnosis.

There is a single instance in which occult blood in urine can be normal. This instance is when you are a woman who is menstruating. Always make sure you are not on your period when collecting urine samples for an occult blood test. If you were or if you are unsure, you need to do the test again. Discuss this with your physician.
If you are not a woman or if you are sure you were not menstruating at the time you collected the urine sample, then this is not normal. Discuss these results and the next step that needs to be taken with your physician. Do not delay this.
If you are in need of medical assistance, contact your physician.…

Two plus protein means that you have protein in your urine. This can be a sign of kidney disease. The 2 plus means that this was not quantitative. It means that there is “some” protein in your urine but does not tell us how much. Hematuria Causes and Risk Factors You might have blood in your urine because of: Urinary tract or kidney infections. Bladder or kidney stones. Certain kidney diseases, such as inflammation in the filtering system (glomerulonephritis) An enlarged prostate (benign prostatic hyperplasia) or prostate cancer.

In urine, you normally expect little to no red blood cells. In this context, it would mean 0–2 red blood cells per high powered field. When you start seeing amounts like this you start to question whether the person was doing strenuous exercise (if they’re there for routine or pre-op lab work), or if it could mean something more serious, like a bleed or kidney disorders.
However, leave the interpretation of your results to your doctor, since they’ll have a more complete picture about your medical history.
Hope this helps.

Many things can cause hematuria (blood in urine) and we typically classify hematuria as being painful or painless. Here’s a list of some reasons but not all reasons :
- strenous exercise- if you have little (perinephric) fat and go run a marathon your kidneys are bouncing around in your retroperitoneum and this can cause trace blood in urine.
- Kidney stone – stones irritate the ureters and cause blood in urine. This is a painful cause of hematuria
- bladder cancer – painless hematuria, usually men 60s or older with a history of tobacco smoke
- urinary tract infection – when lining or your urinary system is inflamed from infection (or non infectious causes) you can have blood in your urine
- anticoagulation- many many people take drugs that thin their blood and or block production of platelets (ie- aspirin, plavix, Coumadin, xaralto, lovinox, etc) and all these meds can cause you to bleed in your urine
- trauma – sex can injure the urethra and lead to hematuria , more severe trauma like pelvic fracture leading bladder rupture or urinary tract injury
- foley insertion – like sex this can also be traumatic to urethra if not done correctly
- Medications – meds like ibuprofen , Motrin , naproxsyn and other NSAIDs are all nephrotoxic if used for prolonged periods and can cause parenchymal damage leading to hematuria
- rhabdomyelisis- muscle breakdown caused by severe over use , dehydration, cocaine use, meds can cause hematuria or mimic it because of the myoglobin released by crushed/injured myocytes
- polycystic kidney disease- genetic disorder that causes people to have many cysts on their kidneys (and liver) cysts can be hemorrhagic and lead to hematuria
- No! Not safe . Pus cells in urine is an indication of an infection most likely a urinary tract infection. Pls see a doctor to evaluate you further . An infection of the kidney called pyelonephritis maybe a cause . In some cases of chronic urinary tract infection , the patient may not feel much symptoms or may simply ignore its subtle ,often intermittent pain on the flanks and dark smelly urine . Urine has its own ammonia smell but a urine with pus cells would have a different type of smell .
- A notmal urine should not have any pus cells or at worse 0–1 Hpf under the microscope.
- a rental ultrasound is advised after a clinical examination by a physician .
- the long term consequence of an untreated, persisting kidney or longstanding urinary tract infection is kidney failure .
Both or these are findings in a urinalysis. Occult means hidden. This is blood that isn’t visible to the eye but that is detectable by testing for it and is visible under a microscope. In urine dipstick testing, 1+ and above indicates significant hematuria, blood in the urine. A trace amount is a negative result. RBCs, or red blood cells, are seen in a microscopic urinalysis, when the specimen is examined under a microscope. Generally speaking, more than 3–5 RBCs per HPF is concerning. And, no, these results aren’t normal but I don’t believe the results given should be alarming but they do merit attention. Lots of things cause hematuria, I can’t emphasize that enough, including strenuous exercise and minor trauma, even trauma from masturbation. I’m not going to get into explanations of power fields and microscopes — you can look into that on your own time, if you care to.
In the future, please review test results with the ordering physician instead of posting them online and asking the general public. It’s a distinct mistake to post test results online and ask for interpretation. I strongly suggest you refrain from doing this again.
What does Urine positive for occult blood means? I had a physical examination indicting i have “Urine positive for occult blood”, I searched and found it’s about kidney.I have other symptoms like frequent micturition, dry lips, occasional pains in liver and stomach, and more pains in liver when running. what’s more i have grey hair a lot.
“Occult blood” means microscopic blood – it would not be obvious from looking at your urine that there was blood in it. Frequently, the causes involve some condition of the kidney, such as an infection or kidney stones. Sometimes, the test is a false positive, meaning some factor made it seem like there was microscopic blood in the urine when there actually is no blood there. Factors that can cause a false positive test result include dehydration and excessive exercise. Please discuss your test results with your doctor to determine what they mean in your case.
If you aren’t close to your period, then we can assume the red cells came from your urinary system. That can be from inflammation of the bladder, parasites exiting through the bladder wall (Schistosoma), free hemoglobin from a hemolytic anemia, bladder cancer, kidney stones, prostate cancer, urethritis from STD’s. Why don’t you see a doctor and let him help you sort it all out.
In a young male or postmenopausal female, it is probably significant. In all others, it may be significant and should be ruled out or in by further history where it might be coming from.
If they have a bladder infection (UTI), then clear it up and repeat the UA (urinalysis) test 2 weeks after the last dose of antibiotics. If they are still there (3–5) then further work needs to be done.
If they are close to the end of their menses (period), then a repeat UA in 2 weeks should show no red cells … if they still have red cells, it needs further work-up.
There are lots of reasons for red cells in the urine and some are “normal siting’s” and some are pathologic. My postmenopausal wife had a kidney removed and didn’t need CHEMO because her doctor took 3–5 red cells that repeated as something to look into. An ultrasound got her a trip to a urologist where they biopsied it and watched it’s growth until 7 mm. at which time it was “actionable” by Medicare rules.
Occult means hidden in medical terminology, so occult blood in urine or faeces can indicate bleeding in the bowel or bladder. There can be a few reasons for the presence of the blood. In urine it can indicate an infection in the bladder,usually confirmed by a laboratory analysis and Appropriate treatment as indicated by the sensitivity test conducted by the lab. A 2+ result could also indicate a tumour in the bladder, so it’s important to follow your doctor’s advice re any diagnosis.
