Is weak positive urine occult blood a big problem?

Urine occult blood is a common urine test method. It checks some red blood cells in the urine to see whether the red blood cells have increased. Under normal circumstances, it should be negative. If there are a small number of red blood cells, it may show a weak positive. Don’t worry too much at this time. It may be a false positive, especially for some women because of their menstrual period. Of course it is best to check again.

Is weak positive urine occult blood a big problem?

Weakly positive urine occult blood is the result of a routine urine test, which is between negative and positive. More optimistic than positive, but not a serious problem either. If you are a woman, during your menstrual period, you may accidentally mix menstrual blood into your urine sample, resulting in a false positive. If this is not the case, be careful of the following situations: one is urinary system stones. The second is urinary system tumors. The third is trauma. It is recommended that people with this condition have a recheck. If red blood cells are still present, further tests should be performed to confirm the diagnosis.

For occult blood in urine, we must first determine whether there are red blood cells in the urine, or the urine is contaminated, or there is some infection, or some transient red blood cells due to excessive exercise. It is not enough to judge based on routine urine test alone. Generally, 1-2 red blood cells are not considered abnormal. If there are no symptoms, repeat the routine urine test several times. If there are still a series of tests such as urine MDI, bilateral kidney ureter, and renal vein B-ultrasound, it is recommended to repeat the routine urine test first and then see a professional doctor.

Causes of occult blood in urine

Generally speaking, occult blood in urine is attributed to the following three reasons: inflammation, stones, and tumors. Regarding inflammation, such as glomerulonephritis, pyelonephritis, cystitis, etc., in addition to hematuria, occult blood may also occur in urine tests. The stones themselves, whether they are kidney, ureter or bladder stones, may cause occult blood. Other situations such as constipation during menstruation may also cause occult blood. In addition, tumors can also cause occult blood, such as benign or malignant tumors of the kidney, bladder, and ureter. Of course, older men have prostate hypertrophy and excessive residual urine, which makes the bladder prone to inflammation. The blood vessels on the surface of the prostate are congested, and they have difficulty urinating. After straining to urinate, they may have hematuria or occult blood. In fact, prostate hypertrophy is also a type of tumor. It is a tumor of the prostate, which becomes enlarged due to proliferation. Therefore, tumors of the urinary tract should not be taken lightly. At this time, intravenous pyelography should be performed. If there is no problem with the angiography, transitional cell tumor can be ruled out. Urinalysis should also be checked regularly. If there is still occult blood, you should go to the nephrology department for treatment and perform a renal puncture biopsy if necessary.
