White Blood Cells In Urine No Nitrates – Written by: Dr. Katherine Klos, MD makes UTI Test Strips, an at-home diagnostic that detects substances in the urine that are commonly present with UTIs, nitrites and leukocytes. However, sometimes it is difficult to say – is a UTI present or not? Here we explore how the UTI test works, and how to help you read your results.

A UTI can be a painful reminder of your urinary tract. Most days, a bathroom break is a welcome break from the dot, the door or the door (if you can close the bathroom door fast enough).

White Blood Cells In Urine No Nitrates

When bacteria colonize the bladder, the discomfort is fullness of the bladder, burning urine and the need for hyperactive urination, nothing but a break. If the bodies were only simple, it would be an obvious sign of UTI to the onlooker. Wouldn’t it be nice if your urine turned purple with the infection? Don’t deny UTI the color of grape soda with urine.

Unfortunately, UTIs are not that simple, and trying to identify symptoms from bladder irritation, dryness or hormone changes, to name a few, can be difficult. Enter – UTI Test Takes Off.

Our UTI Test Strips are home diagnostics that detect substances in the urine that are commonly present with UTIs. While the results of the UTI Test Cloud are important to understand, you need to set yourself up to conduct the test and administer the test properly.

Leukocyte esterase (LE) is an enzyme or protein produced by the lysis, or breakdown, of white blood cells (WBC’s). WBCs are associated with inflammation and fighting infection, so they are commonly present with UTI.

In the UTI Test link package, color-coded strips help you explore the strip test results. The top panel tests for leukocytes and the bottom panel tests for nitrites. If both pads are purple in color, this is an obvious sign that a UTI is most likely present.

The first line in the UTI Test Strip detects the absence, presence or abundance of WBC in the urine.

Detection is indicated as a color change from white to pink in the test strip. A white color indicates a lack of LE and a white rose is associated with elevated WBC levels.

The color spectrum ranges from white to pink in the test strip for various levels of LE. WBCs can also be present in the urine with viral infections, kidney stones, drugs, and even after exercise.

Nitrite compounds are produced when certain bacteria containing the enzyme nitrate reductase destroy urea (a nitrate waste product). An important point of clarification, nitrites are not

You are not The second line of the UTI Strip Test detects the absence, presence or abundance of nitrites in the urine as the reflex changes in color from white to purple.

White color does not indicate high nitrite detection and purple, consistent with elevated nitrite. Again, the color spectrum varies from white to pink in the correlative nitrite test strip.

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 can change color with exposure to air and from urine dyes common in over the counter products used to treat UTI symptoms. Additionally, a low nitrate diet can make it difficult to detect nitrites in the urine.

Research has shown that there is a 98% sensitivity for UTI with the detection of nitrites and LE, which makes the UTI Test an effective at-home diagnostic test. As each bladder is unique, UTIs vary widely, and it is always important to seek accurate diagnosis and treatment. UTI Tests help clear the way for your journey to understanding your whole body and your health.

How To Read Urine Test Strips

For help, see below a sampling of some cases of use with UTI Test Strips. As always, if there is any trace of information or a pad in the card, it is recommended to inform your doctor and seek the appropriate treatment.

Results: Infection is most likely present. With both pads showing clearly in the purple area, it is more likely that a UTI is present. Consult a doctor ASAP for treatment.

Results: The infection is present. If LE is detected in the urine, it is usually used to inflame the body and fight infection. Negation of nitrite does not exclude the issue of use. Consult a doctor for treatment.

Results: A UTI is not likely present based on the urine results. However, if you are experiencing symptoms, it is still important to talk to your doctor and try again. Note: a negative test does not completely rule out the effects of infection.

It can be used to diagnose and monitor a variety of medical conditions, including kidney disorders; urinary tract infections; and systemic diseases, such as diabetes mellitus.

During urinalysis, a urine sample is collected into a sample cup and analyzed. The first part of the urinalysis involves direct observation to assess the color, clarity, and odor of the urine. Next, the urine is analyzed using a dipstick test, or a urine test strip, where a chemist treats it, strips the paper, drops it in the urine sample, and matches it with certain substances in the urine, thereby changing the color. Color changes can be read either manually by comparing the colors of the dipstick to the manufacturer’s guide or automatically by special lab equipment that provides more accurate test results. The last step of the urinalysis is a microscopic examination, which is performed manually on the sediment from the centrifuged urine sample.

Urinalysis tests the chemical and microscopic properties of urine. The exact tests included vary depending on the dipstick test, but common ones are urine pH, specific gravity, blood, proteins, glucose, ketones, white blood cells (leukocyte esterase), nitrites, bilirubin, and urobilinogen. Microscopic examination can determine the presence of solid particles in the urine, such as red or white blood cells, epithelial cells, urinary casts, microorganisms, and crystals.

Urine pH is usually slightly acidic, although it can vary from as low as 4.5 to as high as 8.0 depending on the body’s acid-base balance. The formation of kidney stones is strongly influenced by urinary pH. Acidic urine helps the crystallization of uric acid or cystine stones, while alkaline urine contains calcium and phosphate. Alkaline urine can result from infection with urea-splitting bacteria, such as Proteus mirabilis, Klebsiella, or Pseudomonas—which break down urea molecules into ammonium and carbon dioxide, increasing urine pH to a neutral or alkaline value. Urinary pH levels are also affected by cleanliness factors. A high-protein diet can cause acidic urine, while eating a low-protein diet can cause alkaline urine.

Specific gravity measures the kidney’s ability to dilute or dilute urine by comparing its density with that of distilled water (1,000). Since urine contains various solutes, it has a higher specific gravity than water, usually from 1.005 to 1.025. A high specific gravity represents strained urine, and can be increased by dehydration or levels of solutes in the urine. A low specific gravity, on the other hand, represents diluted urine and can occur with high fluid intake, diabetes insipidus, or due to kidney disease when the kidney’s ability to absorb urine is impaired.

The presence of blood in the urine is known as hematuria. It can be classified as gross hematuria, when seen with the naked eye, or microhematuria, when it can only be detected using a microscope. Hematuria can occur for a variety of reasons, including damage to the kidney’s glomerular filtration barrier, which typically prevents blood from passing into the urine; injuries to the urinary tract, such as urinary tract infections, kidney stones, or tumors; as well as systemic disorders such as vasculitis, lupus, tuberculosis among others. In menstruating persons, blood in the urine may occur due to infection of the urine specimen.

In a healthy individual, urine contains only a small amount of protein because usually protein molecules, such as albumin, are too large to pass.
