WBCs (White Blood Cells ) in Urine

The presence of WBCs in urine, also known as leukocytes, can indicate an underlying medical condition. Normally, urine does not contain any white blood cells, but in the presence of an infection or inflammation in the urinary tract, white blood cells may be present.

Increased in WBCs in urine is called Pyuria.

Introduction of WBcs in Urine:

The presence of white blood cells in urine, also known as leukocytes, can indicate an underlying medical condition. Normally, urine does not contain any white blood cells, but in the presence of an infection or inflammation in the urinary tract, white blood cells may be present. This can be caused by various conditions such as urinary tract infections, kidney stones, and sexually transmitted infections. If you have white blood cells in your urine, it is important to see a healthcare provider for evaluation and treatment.

Causes of WBCs in Urine:

Here are some common causes of white blood cells in urine:

1. Urinary tract infections: Bacterial infection in the urinary tract can lead to white blood cells in urine. Symptoms include frequent urination, painful urination, and cloudy urine.
2. Bladder infections: Infection in the bladder can cause white blood cells in urine. Symptoms include frequent urination, urgency, pain or burning during urination, and lower abdominal pain.
3. Kidney infections: Infection in the kidneys can lead to white blood cells in urine. Symptoms include fever, chills, flank pain, nausea, and vomiting.
4. Sexually transmitted infections: Certain sexually transmitted infections (STIs) such as chlamydia and gonorrhea can cause white blood cells in urine. Symptoms may include painful urination, discharge, and genital itching or pain.
5. Interstitial cystitis: This chronic condition causes inflammation in the bladder and can lead to white blood cells in urine. Symptoms include frequent and painful urination, pelvic pain, and discomfort during sex.
6. Kidney stones: Presence of kidney stones can cause urinary tract obstruction and lead to urinary tract infection, which in turn causes white blood cells in urine. Symptoms include sudden onset of severe pain in the back or side, nausea, and vomiting.
7. Prostate infection: Infection in the prostate gland can cause white blood cells in urine. Symptoms include painful urination, difficulty urinating, and frequent urination, especially at night.

It’s important to note that this is not an exhaustive list, and other medical conditions or factors could also lead to the presence of white blood cells in urine. A healthcare provider should be consulted for proper diagnosis and treatment.

Why get tested:

Some reasons why a healthcare provider may recommend getting tested for white blood cells in urine:

1. Urinary tract infection symptoms: If you’re experiencing symptoms such as painful urination, frequent urination, or cloudy urine, your healthcare provider may recommend a urine test to check for the presence of white blood cells in urine and determine if you have a urinary tract infection.
2. Routine physical exam: A healthcare provider may order a urine test as part of a routine physical exam to screen for any potential health issues, including the presence of white blood cells in urine.
3. Follow-up after treatment: If you’ve recently been treated for a urinary tract infection or other condition that can cause white blood cells in urine, your healthcare provider may recommend a urine test to ensure that the treatment was successful and that there are no remaining issues.
4. Monitoring a chronic condition: If you have a chronic condition such as interstitial cystitis or kidney stones, your healthcare provider may recommend regular urine tests to monitor the condition and detect any potential flare-ups or complications.
5. Screening for sexually transmitted infections: If you’re at risk for sexually transmitted infections, your healthcare provider may recommend a urine test to check for the presence of white blood cells in urine, which can indicate the presence of an STI.

It’s important to discuss with your healthcare provider if you have any concerns or questions about the need for a urine test or other medical tests.

When to Get Tested:

Here are some situations when you may need to get tested for white blood cells in urine:

1. If you experience symptoms of a urinary tract infection, such as painful urination, frequent urination, or cloudy urine.
2. If you have a history of urinary tract infections or other conditions that can cause white blood cells in urine, and you develop similar symptoms.
3. As part of a routine physical exam, especially if you are at risk for urinary tract infections or sexually transmitted infections.
4. If you have a chronic condition such as kidney stones or interstitial cystitis, and your healthcare provider recommends regular urine tests to monitor your condition.
5. If you have been treated for a urinary tract infection or other condition that can cause white blood cells in urine, and your healthcare provider wants to ensure that the treatment was successful and there are no remaining issues.
6. If you are at risk for sexually transmitted infections, such as having multiple sexual partners, and your healthcare provider recommends testing for STIs.
7. If you are pregnant, as urinary tract infections can be more common during pregnancy and may require treatment to prevent complications.

It’s important to discuss with your healthcare provider if you have any concerns or questions about when to get tested for white blood cells in urine.

Required Sample and Preparation:

Here is a list of required sample and preparation for testing white blood cells in urine:

1. Urine sample: A urine sample is required for testing white blood cells in urine. It’s important to collect a clean-catch midstream urine sample, which means first passing some urine into the toilet and then collecting a sample of urine in a sterile container. This helps to avoid contamination of the sample and ensures accurate results.
2. Preparation: Before collecting a urine sample, it’s important to clean the genital area thoroughly with soap and water to reduce the risk of contamination. It’s also important to avoid using any disinfectants or antiseptics, as these can interfere with the test results.
3. Timing: The urine sample should be collected in the morning, as it is usually more concentrated and may provide a more accurate result. It’s also important to avoid drinking too much fluid before collecting the sample, as this can dilute the urine and affect the test results.
4. Storage: The urine sample should be stored in a sterile container and kept refrigerated if it cannot be tested immediately. It’s important to follow any instructions provided by the healthcare provider or laboratory for sample collection and storage.

It’s important to discuss with your healthcare provider if you have any concerns or questions about collecting a urine sample or preparing for a white blood cell urine test.

Results Interpretation:

Here are possible interpretations of results for white blood cells in urine:

1. Negative result: A negative result means that no white blood cells were detected in the urine sample. This is a normal finding and suggests that there is no infection or inflammation in the urinary tract.
2. Positive result: A positive result means that white blood cells were detected in the urine sample. This can indicate the presence of an infection or inflammation in the urinary tract.
3. Elevated levels of white blood cells: The number of white blood cells in the urine sample can provide additional information about the severity of the infection or inflammation. Higher levels of white blood cells may indicate a more severe infection or inflammation.
4. Further testing required: In some cases, further testing may be required to determine the underlying cause of the white blood cells in the urine. This may involve additional urine tests, blood tests, or imaging studies.
5. False positive or false negative result: It’s possible for the results of a white blood cell urine test to be incorrect due to factors such as contamination of the sample or an error in the testing process. In some cases, repeat testing may be necessary to confirm the results.

It’s important to discuss the results of a white blood cell urine test with your healthcare provider, who can provide a more detailed interpretation and recommend any necessary follow-up testing or treatment.

Normal levels of WBCs in urine:

Normally, there should be no white blood cells or very few (less than 5 white blood cells per high power field) in a urine sample of a healthy person. However, the normal range of white blood cells in urine can vary slightly depending on the laboratory and the testing method used. Your healthcare provider can interpret the results of your white blood cell urine test and determine if the levels are within the normal range or if further testing is required. It’s important to note that the presence of even a small number of white blood cells in the urine may warrant further investigation, especially if accompanied by symptoms such as painful urination or frequent urination.

Symptoms of WBCs in urine:

Here are common symptoms that may be associated with the presence of white blood cells in urine:

1. Painful or burning sensation during urination: This may indicate a urinary tract infection.
2. Frequent urination: This may indicate an infection or inflammation in the urinary tract.
3. Urgent need to urinate: This may indicate an infection or inflammation in the urinary tract.
4. Cloudy or strong-smelling urine: This may indicate an infection or inflammation in the urinary tract.
5. Blood in the urine: This may indicate an infection, inflammation, or other underlying condition.
6. Lower abdominal pain or discomfort: This may indicate an infection or inflammation in the urinary tract.
7. Fever or chills: This may indicate an infection in the urinary tract or elsewhere in the body.
8. Nausea or vomiting: This may indicate an infection or inflammation in the urinary tract or other underlying condition.
9. Back pain or flank pain: This may indicate a kidney infection or other underlying condition.

It’s important to note that not all people with white blood cells in their urine will experience symptoms. If you are experiencing any of these symptoms, it’s important to discuss them with your healthcare provider, who can recommend appropriate testing or treatment.

Treatment and Preventions of WBCs in Urine:

Here are possible treatments and preventative measures for white blood cells in urine:

1. Antibiotics: If the white blood cells in the urine are due to a bacterial infection, antibiotics may be prescribed to treat the infection.
2. Antifungal medication: If the white blood cells in the urine are due to a fungal infection, antifungal medication may be prescribed to treat the infection.
3. Pain relievers: If you are experiencing pain or discomfort, over-the-counter pain relievers such as ibuprofen or acetaminophen may be recommended.
4. Increased fluid intake: Drinking plenty of water and other fluids can help flush out bacteria and other harmful substances from the urinary tract.
5. Urinate frequently: Urinating frequently and completely can help prevent bacteria from multiplying in the bladder.
6. Good hygiene: Practicing good hygiene, such as wiping front to back after using the toilet, can help prevent the spread of bacteria to the urinary tract.
