The urine test says it s occult blood, what s going on, what s going on with the urine test

What is occult blood in the urine.

Q: What is occult blood in the urine? What does occult blood mean in the urine?

Urine occult blood is a name, that is, there is "potential bleeding" in the urine, which is detected by urinalysis. If there is an increase in red blood cells (normal is negative, denoted by "—"), a small number of them can become urine occult blood (positive, denoted by "+") in terms of their number.

A positive urine for occult blood can only indicate that the urine contains red blood cell components, but this is not really a morphological, intact red blood cell seen under the microscope, but a red blood cell component that is examined by a computer. The red blood cells in the normal human body are constantly destroyed, and their components are excreted from the urine, so some normal people will also have occult blood positive in the urine. In general, red blood cells (RBCs) have a high magnification field of view and are in the normal range.

Hematuria is diagnosed when there are more than 3 HP red blood cells in the urine on microscopic examination.

Urine occult blood is an indicator when a person's urine is routinely examined. One of the tests in the urinalysis is to check the number of red blood cells in the urine. If there is an increase in red blood cells (which is normally negative), a small number of them can be called occult blood in the urine.

Urine occult blood as an indicator can be divided into negative and positive. If positive, it is several pluses. Urine occult blood is usually caused by a kidney problem or a urinary tract infection.

Occult blood, indicating that there are diseases of the urinary system, such as: inflammation, stones, etc.

Further tests are done.

It is an infection of the urinary tract.

There are many people who will find that there is occult blood in the urine when they are examined, most of which are caused by inflammation.

1.First: since it is bleeding, the base of the jujube is mostly caused by inflammation stones, tumors, etc., in the case of vascular destruction or increase in the size of the blood vessels, not only red blood cells will leak out, but also the protein in the plasma will seep out, and the protein qualitative will also appear positive to varying degrees, and there are red blood cells in the microscopic examination.

The urine is reddish.

2.Second: In the case of very little bleeding, urine protein is characterized as normal, red blood cells are damaged by acid and alkaline substances in the urine and red blood cells cannot be found by the microscope, it can be determined by multiple urine tests or urine sediment to check whether there are red blood cells.

Large amounts of hemolysis can cause changes in the color of the urine, which is tan or dark brown.

3.Second: in the case of very little bleeding, urine protein is normal, red blood cells are destroyed by acid and alkaline substances in the urine and red blood cells cannot be found by the microscope, it can be determined by multiple urine tests or urine sediment to check whether there are red blood cells.

Large amounts of hemolysis can cause changes in the color of the urine, which is tan or dark brown.

Precautions. Occult blood is invisible blood, if this happens, most of it is caused by the destruction of red blood cells, so pay attention to the examination and **.

The phenomenon of urine occult blood is invisible to the naked eye, which is caused by the destruction of red tremor Jingchang cells, so we should know more about this knowledge, and today we will introduce what is going on with urine occult blood.

1.First, the presence of red blood cells in urine occult blood cannot be observed with the naked eye or under the microscope, but if it is tested with a test strip, why is it so?

Because when red blood cells are destroyed, the heme contained in them is released, so the heme response can only be detected by the urine test rod.

2.Second: Generally speaking, urine occult blood is attributed to the following three causes, one is inflammation, one is stones, and then tumors. Regarding inflammation, such as glomerulonephritis, pyelonephritis, cystitis, etc., in addition to hematuria, occult blood may also occur in urine tests.

3.Third: In addition, tumors can also cause occult blood, such as benign or malignant tumors of kidneys, bladder, ureters, of course, older men because of prostate hypertrophy and because of excess urine, bladder inflammation, prostate surface blood vessel congestion, plus difficulty in urination, after vigorous urination, hematuria or occult blood may occur.

Precautions. Everyone is worried about the existence of this disease and is afraid that they will have nephritis. There are many children who also suffer from this disease, and this disease keeps recurring, I hope everyone is reasonable**.

Occult blood is the composition of broken red blood cells, if the red blood cells are oranges, occult blood is fruit oranges--- if there are white blood cells in the urine routine, the general occult blood ** is a urinary tract infection. Long-term occult blood excludes urinary tract infection and stones, and the possibility of nephritis is relatively large, and the harm of simple occult blood positive is not ---

During the menstrual physical examination, occult blood is generally positive--- so the laboratory test should be avoided during menstruation--- the proportion of occult blood positive in middle-aged and elderly women is relatively large---

If there is no other problem, the occult blood caused by nephritis is generally used with nephritis ** tablets, as well as the antiplatelet aggregation --- of dipyridine

1+ occult blood, it is recommended to rest and recheck, the problem is not big - there is basically no need for **, and the urine routine review is --- once a month

There are many causes of hematuria.

1. Urinary system diseases such as various nephritis (acute glomerulonephritis, viral nephritis, hereditary nephritis, purpuric nephritis), stones (kidney, bladder, urethra), heart and kidney tuberculosis, various congenital malformations, trauma, tumors, etc.

2. Systemic diseases such as bleeding disorders, leukemia, heart failure, sepsis, vitamin C and K deficiency, hypercalciuria, neonatal symptoms, etc.

3. Physical and chemical factors such as food allergies, radiation exposure, drugs, poisons, post-exercise, etc.

It is recommended that you repeat the test, if the urine is still positive for occult blood, further tests are required for targeting**.

Hello. A urine test should only make sense in conjunction with your symptoms and other tests.

If there is no other discomfort, just one occult blood positive one + should be fine.

Repeat urinalysis at intervals is recommended.

Also, don't get overtired.

Occult blood is usually caused by a urinary tract infection or a kidney problem.

You can test the morphology of red blood cells in your urine to confirm that it is symptomatic.

Hello, there are many common causes of hematuria, such as various nephritis, urinary tract infection, hemorrhagic cystitis, urinary stones, renal tuberculosis, kidney tumors, kidney and urethral damage, etc., it is recommended that you can go to the hospital to do a urine red blood cell morphology analysis, kidney B ultrasound and other examinations, clear diagnosis, symptomatic **, usually pay attention to light diet.

Hematuria is often caused by diseases of the urinary organs. Human urine is produced in the kidneys and excreted through the renal pelvis, ureters, bladder, and urethra.

Common diseases that cause hematuria include various nephritis, urinary tract infections, hemorrhagic cystitis, urinary stones, renal tuberculosis, kidney tumors, kidney and urethral injuries, etc.

Therefore, you are not yet able to confirm the diagnosis, and you need to check the morphology of urine red blood cells to confirm the hematuria**, in time**.

There are many causes of hematuria, which may be urinary tract infection, stones, nephritis, etc.

Your current condition is not yet diagnostic, and it is recommended that you do a urine red blood cell morphology analysis to determine the number of red blood cells**, and diagnose the disease early, as soon as possible**.

The possible causes of hematuria are as follows: 1. Stones, 2 nephritis, 3 nutcracker phenomenon, 4. Urinary tract infection, which can be eliminated by checking one by one, B ultrasound can determine whether there are stones, and nutcracker phenomenon, urinary tract infection will be accompanied by uncomfortable symptoms, urine test has white blood cells, if the above three items are excluded, the possibility of nephritis is considered, it is recommended that you do the urine red blood cell morphology.

There are many reasons, and we need to analyze them specifically!

Urine occult blood is detected by urinalysis, which contains one red blood cell. If there is an increase in red blood cells (normally negative), in terms of its number, a small number can be called urine occult blood, and urine occult blood itself can also be used as an indicator, whether it is negative or positive, if it is positive, how many plus. In general, urinary occult blood is caused by kidney problems or urinary tract infections.
