What Is Red Blood Cells In Urine – A 23-year-old woman presented with hematuria. Her blood pressure was normal and she had no rash, joint pain, or other symptoms. Urinalysis was positive for proteinuria and hematuria, and urinalysis showed dysmorphic red blood cells (RBCs) and red cell casts, leading to a diagnosis of glomerulonephritis. She had proteinuria of 1.2 g/24 hours. Laboratory tests for systemic disease were negative. Renal biopsy study revealed stage III immunoglobulin A (IgA) nephropathy.

Glomerular hematuria may represent an immune-mediated injury to the glomerular capillary wall, but may also be present in non-inflammatory glomerulopathies.

The type of dysmorphic erythrocytes (crenate or deformed cells, acanthocytes) may be of diagnostic importance. Notably, dysmorphic red cells alone may be predictive of renal bleeding alone, whereas acanthocytes (ring-shaped RBCs with vesicle-like protrusions best seen on phase contrast microscopy) appear to be most predictive of disease glomerular.

The presence of acanthocytes comprising at least 5% of excreted erythrocytes had a sensitivity of 52% for glomerular disease and a specificity of 98%.

In vitro, changes in osmolality or pH do not produce dysmorphism, but may occur along different tubular segments.

In addition, RBCs can lose their shape when crossing the glomerular basement membrane (Figure 1) and during passage along the tubular system.

A red blood cell (red arrow) is seen crossing the basement membrane (blue arrow) and losing its shape, one of the proposed mechanisms for acanthocyte formation; the yellow arrow indicates the urinary space (Masson trichrome stain, ×1,000.

And dysmorphic erythrocytes in the urinary sediment (Figure 2) are also considered to represent renal pathology. On electron microscopy, the glomerular basement membrane is typically 300 to 400 nm wide, whereas the diameter of red blood cells is 7 μm. RBC shape change is manifested by blebbing, budding, and segmental membrane loss, resulting in marked shape variability and a reduction in average cell size. These changes may be due to mechanical trauma as cells pass through breaks in the glomerular basement membrane and to osmotic trauma as cells flow through the nephron. Red blood cells (RBCs) can be present in urine even when they are not visible to a person. . Also known as hematuria, it can indicate an infection, kidney disease, and other health conditions.

There are two types of hematuria. One is called “gross hematuria,” which occurs when a person can see blood in the urine. The other type is “microscopic hematuria,” where a person cannot see blood in the urine, despite the fact that RBCs are present.

However, RBC in the urine is usually a symptom of an underlying health condition. A doctor will usually test the RBC content during a urine test. They will then use the results to determine what the next course of action should be.

Some medications can also cause RBCs in the urine. Some potential medications that can lead to RBCs in the urine include:

In some cases, a person may not experience any additional symptoms of RBCs in the urine. However, some of the conditions listed above can also cause pain, swelling or fever.

If a person notices blood in their urine, they should talk to their doctor as soon as possible.

In most cases, a doctor will discover RBCs in the urine during a urinalysis. A urinalysis checks for several key health indicators after providing a urine sample.

Urinary Red Blood Cells: Not Only Glomerular Or Nonglomerular

The ideal sample uses the “clean catch” method. The clean collection method involves starting the urine stream and placing the collection cup in the middle of the stream. This helps eliminate any potential contamination from bacteria or other substances that may be near the genitals.

In some cases, a doctor may use a simple dipstick to test the urine for blood. A dipstick is a piece of paper with chemicals on it. These chemicals react with various substances that may be present in the urine. When searching for RBC, a dipstick will turn a different color if RBC is present.

After this, the doctor will send the sample to a laboratory for further tests. Laboratory personnel can provide more information about the amount of RBCs, as well as any other substances that may indicate an underlying condition, in the urine.

A very small amount of RBCs may be present in a normal urine sample. In fact, according to the Icahn School of Medicine at Mount Sinai in New York, the normal range for RBCs in urine is up to four RBCs per high-power field.

However, different labs may have different ranges for a “normal” result. For this reason, a person may want to talk to their doctor about what the test results mean.

An abnormal range can indicate any of a number of potential problems. Some of the possible conditions include:

If a test shows that a person has RBCs in their urine, a doctor will likely run additional tests. For example, they might want to:

A doctor will also ask about any other symptoms a person is experiencing that could indicate an underlying health condition. A person should discuss their concerns with their doctor before providing a urine sample.

It is also important to note that sometimes a test can give a false reading. This can occur if a person takes the test during menstruation, for example. In this case, blood can enter the urine sample and cause a false reading.

Pregnant women should not see blood in their urine. If they do, they should notify the healthcare team immediately. If they provide a urine sample with blood in it, a doctor will try to diagnose and treat any underlying conditions.

RBC in the urine may indicate that there is a problem with the urinary tract. If a person discovers blood in their urine, they should contact their healthcare provider.

If a test confirms the presence of red blood cells in the urine, a doctor will likely want to run additional tests to find out what’s causing it. Often the cause is treatable.

Healthcare providers can help you find the cause and the best treatment.

Urine can tell a health story, with colors ranging from pale yellow to yellow to amber to red, with red indicating possible bloody urine (hematuria).

Hematuria is the medical name for the presence of blood cells in the urine (pee). Healthcare providers label blood in the urine as gross, microscopic, or dipstick.

What Do Leukocytes In Urine Mean?

Blood in the urine is a common finding. It affects about 2% to 30% of the US adult population.

There can be a number of different causes of blood in the urine, some more serious than others. These conditions may involve infections or stones, including:

In addition to these other conditions, cells that grow out of control in certain parts of the body – what we know as cancer – can cause blood in the urine. These conditions include:

Often, there are no symptoms except for blood in the urine. When this happens, your providers may say you are “asymptomatic.” If you have symptoms, they may include frequent or painful urination, or urination that is urgent or needs to happen “right away.” Nausea, vomiting, fever, chills, or pain in the back or lower abdomen may also be associated.

Paroxysmal Nocturnal Hemoglobinuria

While blood in your urine doesn’t always mean you have an illness, it can be an important warning sign of a possible health problem.

Never ignore bloody urine. Contact a healthcare provider as soon as you find blood in your urine, as early detection of any problem is helpful.

During your appointment, your healthcare provider will take a medical history and perform a physical exam that may include a pelvic exam or a digital rectal exam. These things will help your provider better understand your symptoms. Your provider may order other tests. These tests may include:

Treating blood in the urine depends largely on the actual cause of the hematuria. Your provider will use information gathered from your medical history, physical exam, and test results to work with you to find the best treatment.

Treatments for the causes of hematuria, including drugs and procedures, can each have side effects. These vary depending on the type of treatment.

However, untreated hematuria could lead to bigger problems, especially if the cause is more serious than strenuous exercise. A health care provider should treat any condition that causes blood in you
