What is the significance of white blood cells in urine




















If you do have leukocytes in your urine, your symptoms will vary depending on the condition that is causing the leukocytes to build up in your urine. Obstructions in the urinary tract can cause a range of symptoms depending on the location and type of obstruction.

In most cases, the main symptom is pain on one or both sides of the abdomen. Kidney stones may cause similar symptoms as a UTI but may also include nausea , vomiting , and intense pain. Women tend to be a greater risk for urinary tract infections, and, therefore, more likely to have leukocytes in their urine. Pregnant women have an even higher risk. Men can develop these infections, too. Having an enlarged prostate , for example, raises the risk of UTIs in men. A normal range in the bloodstream is between 4,, WBCs per microliter.

If bacteria are detected, your doctor may perform a urine culture to diagnose the type of bacterial infection you have. A urine test can also aid in the diagnosis of kidney stones. An X-ray or CT scan can help your doctor see the stones. If you get recurrent UTIs, your doctor may prescribe a longer course of antibiotics and further testing to see if there are specific reasons for repeat infections.

For women, taking an antibiotic after sexual intercourse may be helpful, but you should only take prescription medications as recommended by your doctor. In addition to antibiotics, increasing your fluid intake can help flush out a UTI. Drinking more water may seem unappealing if urinating is painful, but it can help speed up the healing process. If an obstruction, such as a tumor or kidney stone, is causing the high leukocyte levels, you may need a surgical procedure.

If you have small kidney stones, increasing the amount of water you drink can help flush them out of your system. Passing stones is often painful. Sometimes, larger stones are broken up using sound waves. Surgery may also be necessary to remove large kidney stones.

Usually, your kidneys prevent protein from passing from your blood into your urine: loops of capillaries glomeruli that filter blood allow small particles to pass into the urine while retaining larger particles, such as protein, and kidney tubules reabsorb the smaller proteins that were able to escape. Large amounts of protein in the urine suggest that these glomeruli and tubules are inflamed or damaged in some way.

If there is a large amount of protein in the urine, your doctor may request that you give a hour urine sample or obtain a random protein to creatinine ratio. These two tests are used to monitor lupus affecting the kidneys lupus nephritis. Glucose : Your urine should not contain glucose.

If it does, your doctor will order further bloodwork and urine tests to determine the cause. Glucose in the urine is called glucosuria; it can occur in people with diabetes that is not properly regulated with insulin, in people with kidney problems that affect the absorption of glucose, in pregnant women, and in people with liver abnormalities or hormonal disorders. Ketones : Ketones in the urine ketonuria indicate that your body is metabolizing its fat reserves instead of carbohydrates to obtain energy.

This can occur in people on low-carbohydrate diets, people who are malnourished, or people who have a problem properly metabolizing carbohydrates e. It can also occur with excessive exercise, loss of carbohydrates due to vomiting, or exposure to cold. In people with diabetes, ketonuria may indicate insufficient management with insulin. Blood : The chemical examination of urine also measures the amount of red blood cells in the urine sample.

The presence of red blood cells in the urine is known as hematuria, and the presence of hemoglobin from red blood cells is known as hemoglobinuria. Usually people have very small amounts of red blood cells in their urine, but even a minute increase can indicate a problem, such as a disease of the kidney or urinary tract, trauma, medications, smoking, or intense exercise e.

When the chemical test for blood in the urine is negative but the microscopic assessment shows the presence of red blood cells, the laboratory will usually check for the presence of vitamin C, which can interfere with test results. Therefore, it is very important to tell your physician if you are menstruating or are experiencing any other condition that could contaminate your urine sample.

Nitrite : Bacteria can convert nitrate to nitrite; therefore, the presence of nitrite in the urine usually indicates a bacterial infection i. However, not all bacteria can convert nitrate to nitrite, so it is possible to have a urinary tract infection while also having a negative nitrite test.

Bilirubin : Bilirubin is made by the liver from old red blood cells; it is then processed by the intestine and excreted from the body. Therefore, healthy individuals do not have bilirubin in their urine.

The presence of bilirubin in the urine indicates that the liver is allowing the substance to leak back into the blood. This can be an early indication of liver disease, even when other symptoms, such as jaundice, are not present. Microscopic Analysis The microscopic examination uses a microscope to identify and count cells, crystals, bacteria, mucous, and other substances that may be present in the urine. As discussed above, the presence of red blood cells in the urine can indicate a problem, such as a disease of the kidney or urinary tract, trauma, medications, smoking, or intense exercise e.
