High Leukocytes In Urine But No Infection – Written by: Dr. Katherine Klos, MD makes UTI test strips, an at-home diagnostic that detects substances in the urine that are often present with a UTI, nitrites and leukocytes. However, sometimes it can be difficult to tell: is a urinary tract infection present or not? Here we explore how UTI test strips work and how to read your results.
A urinary tract infection can be a painful reminder of your urinary tract. Most days, a bathroom break is a welcome respite from a PowerPoint, email, or a two-year-old (if you can lock the bathroom door quickly enough).
High Leukocytes In Urine But No Infection
When bacteria colonize the bladder, the discomfort of bladder fullness, the burning sensation when urinating, and the hyperactive urge to urinate are anything but a break. If only bodies were simple, there would be a clear sign of an impending urinary tract infection. Wouldn’t it be nice if your urine turned purple from an infection? A urinary tract infection with urine the color of grape soda is undeniable.
Leukocytospermia Or Pyospermia
Unfortunately, urinary tract infections are not that simple, and it can be difficult to decipher urinary tract infection symptoms due to bladder irritation, dehydration, or hormonal changes, to name a few. Enter – UTI test strips from .
Our UTI test strips are a home diagnostic that detect substances in the urine that are often present with a UTI. While it is important to understand UTI test strip results, you must prepare for success and perform the test correctly.
Leukocyte esterase (LE) is an enzyme or protein produced by the lysis or breakdown of white blood cells (WBCs). WBCs are associated with inflammation and fighting infections, and are therefore often present in a urinary tract infection.
On the UTI test strip package you will find a color-coded range that will help you decipher the results of your test strips. The top panel tests for leukocytes and the bottom panel tests for nitrites. If both electrodes are purple in color, this is a clear indication that a urinary tract infection is most likely present.
Azo® Uti Test Strips
The first line on the UTI test strip detects the absence, presence, or abundance of white blood cells in the urine.
The detection is shown as a color change from white to pink on the test strip. A white color indicates a lack of LE and bright pink corresponds to increased levels of WBC.
The color spectrum from white to pink on the test strip correlates with different levels of LE. WBCs can also be present in the urine during viral infections, kidney stones, medications and even after exercise.
Nitrites are compounds produced when certain bacteria containing the enzyme nitrate reductase break down urea (a waste product of nitrate). An important point of clarification: nitrites are not

Are not. The second line of the UTI test strip detects the absence, presence, or abundance of nitrites in the urine, as reflected in the color change from white to purple.
A white color indicates no nitrites were detected and deep purple corresponds to elevated nitrites. Here too, the color spectrum from white to pink on the test strip corresponds to different levels of nitrites.
The best detection of nitrites occurs when the urine has been in the bladder for about 4 hours. It is important to note that the nitrite test strip may change color when exposed to air and urine dyes commonly found in over-the-counter products used to treat UTI symptoms. In addition, a low-nitrate diet can make it difficult to detect nitrites in the urine.
Research has shown a 98% sensitivity for UTIs when detecting both nitrites and LE, making UTI test strips an effective home diagnostic test. Just as every bladder is unique, urinary tract infections vary widely and it is always important to seek medical attention for diagnosis and treatment. UTI test strips help pave the way on your journey to understanding your whole body and taking part in your health.
White Blood Cell Count And Cancer: What You Should Know
See below for an example of some usage scenarios with UTI test strips to help you. As always, if trace amounts are seen on a test strip, it is advisable to notify your doctor and seek appropriate treatment.
Results: There is most likely an infection. Both electrodes are clearly in the purple range, indicating that a urinary tract infection is likely to be present. Consult a doctor for treatment as soon as possible.
Results: There may be an infection. If LE is detected in the urine, it is usually a sign that the body has inflammation and is fighting infection. A negative nitrite result does not rule out a urinary tract infection. Consult a doctor for treatment.
Results: Based on your urine results, it is likely that a UTI is not present. However, if you experience symptoms of a urinary tract infection, it is still important to talk to your doctor and retest. Please note: a negative test result does not completely rule out an infection.

Survival in any environment, for any organism, requires adaptability to the surrounding environment, including defense mechanisms. Fortunately, some defense mechanisms are inherited, while others are acquired throughout our life journey. The first line of defense mechanisms in the body is the immune system, which consists of physical barriers such as hair and skin and internal factors, including white blood cells. These cells, regardless of their stage of maturation, are called white blood cells or leukocytes. White blood cells are part of the innate immune system and protect the body against disease and infection, so elevated levels can be a sign of poor health. The number of leukocytes normally varies between four thousand and eleven thousand per microliter of blood. Bruce Blaus.

ISSN2002-4436. – Own work https://commons.wikimedia.org/wiki/File:Blausen_0909_WhiteBloodCells.png Causes of leukocytes in urine It is worth noting that the existence of leukocytes means greater protection, which reflects abnormal exposure to external invaders, such as bacterial or viral infections or abnormal cell growth as mentioned in the causes of the increase in leukocyte count and presence in the urine below. Urinary tract infections can be caused by bacterial, viral, or parasitic organisms, including: Sexually transmitted infections such as Neisseria gonorrhea and Chladia that first affect the urinary system and urethra. Hospital infections, known as nosocomial infections, can result from surgery or catheterization. Bacteria such as Pseudomonas and Staphylococcus aureus are among the causes of hospital-acquired urinary tract infections. Urinary tract stones can cause an increase in the number of leukocytes in the urine, either directly due to the irrational inflammation of their chemical components, or due to the subsequent infection on top of their blockage of the urinary tract. the urinary tract.2 Other causes Cancer, especially that of the urinary tract, and immunological kidney diseases such as systemic lupus can contribute to the increase in the number of white blood cells.3 Inflammations such as chronic prostatitis in people assigned male at birth (AMAB) and vulvovaginitis in people assigned female at birth (AFAB) can cause an increased number of leukocytes in the urine.4, 5 Symptoms The clinical picture of the symptoms is considered informative, rather than an exclusive diagnostic criterion, for process of increase in the number of leukocytes in the urine. These include: 5. Increase in body temperature, either mild or high fever. Shivering as a reflex mechanism of the brain center for the fever. Increased frequency of urination. Pain or stabbing sensation when urinating. Cloudy urine, with or without offensive sensation. odor Lower abdomen, deep-seated pain Urinary discharge, especially in humans AFAB due to the ascending infection from the genital tract. This discharge may be colored and have an unpleasant odor. Hematuria (blood in the urine) in severe infections, urinary tract stones or urogenital cancer. Who is at increased risk? People considered high risk are those who have higher exposure to the causes and risk factors such as: Sexually active individuals, especially those who have unprotected sex. People with low immunity, such as people who are in a coma, have diabetes mellitus or cancer. relying on water with a high salt content, such as water from wells People admitted to hospitals, especially those undergoing urine-related surgical or diagnostic tests, such as endoscopy or catheterization Cross-contamination between people using the same personal items, including towels or underwear Diagnosis The
