Leukocytes And Nitrates In Urine But No Infection – Leukocytes are white blood cells that are vital for protecting the immune system. Leukocytes in the urine may indicate an infection or inflammation in the urinary tract.

The presence of leukocytes in the urine can be a symptom of an infection. A urinary tract infection (UTI) is often the cause of an increase in the level of white blood cells in the urine

Leukocytes And Nitrates In Urine But No Infection

This article explains what an excess of white blood cells in the urine means and how to treat a UTI.

Urine Dipstick: Urinary Nitrites And Leukocyte Esterase

An unusually high number of white blood cells in the urine indicates inflammation or infection of the urinary tract, often in the bladder or kidneys.

A urine test will show this. Pregnant women are tested for urinary tract infections at their first prenatal visit and may need testing at other times during pregnancy. Other people may need testing based on their health, symptoms, or history of repeated infections.

The doctor may do a test strip, in which the chemical strip detects an enzyme called leukocyte esterase, which indicates the presence of white blood cells, usually associated with infection. The dipstick test also detects nitrites, which are the breakdown products of certain bacteria.

The presence of nitrites in the urine is very specific for certain bacterial infections. Nitrites are not found in all types of bacteria.

The absence of leukocyte esterase in the urine means that the urine most likely does not contain white blood cells, so it is not likely to carry infectious agents.

A doctor or laboratory technician can also perform a urine culture. This involves growing bacteria from the urine to identify the cause of the infection.

If the leukocyte esterase test is positive but no nitrites are detected, infection may still be present.

The test is designed for specific bacterial enzymes, which means it can detect specific bacterial infections with greater accuracy. However, it is not very sensitive, which means that the test does not detect all bacterial infections.

The presence of white blood cells in the urine without nitrites can also lead to a false-positive result, indicating a bacterial infection when it is not present. A pathologist or technician will perform further testing to confirm the presence of infection.

This is especially true when there are other causes of inflammation of the urinary tract. Sometimes, leukocytes can get into the urine from the genital tract during sample collection.

To avoid a false positive, people should clean the area around the opening of the urethra before giving the sample, using cleansing wipes and keeping the labia or foreskin aside.

Collect the sample halfway through urination. The initial stream of urine can be contaminated with skin bacteria, so sampling in this way also reduces the risk of a false positive.

Phagocytes are produced in the bone marrow. Their task is to absorb foreign particles, such as bacteria or parasites. It means to surround, absorb and destroy the particle.

Lymphocytes are white blood cells that recognize foreign particles based on previous encounters. They contribute to “adaptive” immunity, the immune system’s sophisticated ability to remember and mount adapted and effective responses to infection.

Lymphocytes produce antibodies. They bind to foreign particles and allow the immune system to remember them later if the same infection occurs.

During pregnancy, the doctor often conducts a urine analysis for the presence of leukocytes. This is the same test that confirms a bladder or kidney infection.

It also checks for certain pregnancy-related conditions. One of them is preeclampsia, or high blood pressure during pregnancy. Protein in the urine and high blood pressure can indicate preeclampsia.

UTIs are common during pregnancy, and doctors often detect white blood cells in the urine, indicating an infection. However, some pregnant women have a bacterial infection in their urine without symptoms.

Most UTIs are caused by manageable infections that a person can treat with antibiotics. A doctor may prescribe a number of different antibiotics, although only certain antibiotics will be prescribed to women during pregnancy.

More severe or serious infections with complications such as abscesses, kidney damage, or any infections that occur during pregnancy may require more intensive treatment, including hospitalization.

The doctor may need to change the course of antibiotics after the bacteria are found. Some bacteria can only be treated with special antibiotics. Urinalysis is part of routine prenatal testing to diagnose any condition during pregnancy, including kidney infections, preeclampsia, and XA pregnancy disorders characterized by high blood pressure, water retention, and protein in the urine. , and gestational diabetes i XA a condition characterized by elevated blood sugar levels due to hormonal and physical changes during pregnancy. . It also determines an increase in leukocytes in the urine during pregnancy, which may indicate the presence of any infection or inflammation of the genitourinary or urinary tract. You may also need a urine test to check the functioning of the mother’s organs (1) (2).

Read on to learn about the causes, risk factors, symptoms, diagnosis, treatment, and prevention of white blood cells or white blood cells (WBCs) in the urine during pregnancy.

Leukocytes, or white blood cells, are part of your immune system and include granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells). Together, these white blood cells help the body fight infections and other diseases.

In general, measuring the white blood cell count is part of a complete blood count (CBC) test (3). However, if a urinary tract infection (UTI) or inflammation is suspected during a routine prenatal checkup, your doctor may suggest a urine test for white blood cells (especially neutrophils). Urine is normally sterile, so the normal range of white blood cells in urine is low, i.e. up to 5 white blood cells per high power field (WBC/HPF) (4).

Understanding The Presence Of Nitrite In Urine

According to Dr. Alan Lindemann, an obstetrician who is also a former clinical assistant professor at the University of North Dakota, Grand Forks, “

White blood cells are elevated in the blood and urine during pregnancy, but the range depends on where you start. If your non-pregnant woman has a white blood cell count of 5,000, then a white blood cell count of 10,000 or 11,000 is probably normal for pregnancy, but if you start your pregnancy with a higher white blood cell count, your white blood cell count may go up to 15,000.

White blood cells in the urine may not indicate a bladder infection, but may indicate problems. Elevated white blood cells may indicate a group B strep infection, so a urine culture is necessary because group B strep bladder infection can cause kidney infection and preterm labor or delivery.

XAlso known as urinary retention, this is a blockage in the flow of urine through the bladder or urethra. . In addition, most immunological changes in the urinary tract peak during this phase (8).

Leukocytes In Urine

Symptoms of white blood cells or white blood cells in urine samples of pregnant women can vary depending on the underlying cause. Some of these symptoms include (13) (14)

There are two ways to test for white blood cells in the urine during pregnancy: a clean urine sample or a sterile catheterization. With more vaginal discharge during pregnancy, sterile catheterization is the most accurate test for white blood cells during pregnancy.

The results of the analysis of leukocyte esterase can be affected by the method of storage of urine samples. There is a possibility that positive samples may become negative after storage for 24 hours (19).

The pellet of a fresh urine sample is centrifuged at 1500 to 3000 rpm for five minutes and resuspended in the remaining liquid for analysis. One drop is placed on a clean slide, covered with a coverslip and examined under a microscope.

X An automatic screening device that analyzes urine to diagnose urinary tract infections (UTIs). . Therefore, urine samples from pregnant women can sometimes be positive for leukocytes (20).

Treatment options may vary depending on the cause and level of elevated white blood cells in the urine. Some standard treatments that can be included in your prenatal care regimen to help balance or lower white blood cell levels during pregnancy include:

Treatment should be initiated soon after the detection of high levels of leukocytes in urine samples to prevent adverse obstetric outcomes. Some of the maternal complications include (10)

Here are some tips that can help prevent elevated white blood cells in the urine and improve maternal health (13) (18):

So. It is normal to have 0-5 WBC/HPF in your urine even during pregnancy. However, if the level is greater than 5 WBC/HPF, it may be a sign of infection or inflammation in the urinary tract and may require treatment (4).

So. In addition to UTI, an increase in leukocytes in the urine of a pregnant woman can be caused by cystitis, pyelonephritis, or various sexually transmitted infections that increase the risk of fatal complications in the fetus. However, fetal death in such cases is rare (10).

An excess of leukocytes in the urine for a long time may indicate a serious infection. Severe infections can also lead to other symptoms. Therefore, timely treatment is vital to avoid negative consequences for the health of the mother and the fetus.

A high level of white blood cells in the urine during pregnancy can occur due to various infections caused by bacteria or fungi. Symptoms of a high white blood cell count depend on the underlying cause, but may include frequent urination, fever, and nausea. This condition is usually detected during routine urination
