Also known as: UA, Microscopic, Urinalysis Microscopic, Urine Analysis, Microscopic

Amorphous Sediment (Only Reported If Detected)

Bacteria

Bacteria are living things that have only one cell. Most bacteria won't hurt you - less than 1 percent of the different types make people sick. Many are helpful. Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli.

Calcium Oxalate Crystals (Only Reported If Detected)

Calcium oxalate is a chemical compound that forms envelope-shaped crystals. A major constituent of human kidney stones.

Casts (Only Reported If Detected)

Urinary casts are cylindrical structures produced by the kidney and present in the urine in certain disease states. They form in the distal convoluted tubule and collecting ducts of nephrons, then dislodge and pass into the urine, where they can be detected by microscopy.

Crystals (Only Reported If Detected)

Abnormal crystals may appear in urine as a result of pathology or due to normal catabolism

Granular Cast (Only Reported If Detected)

The second-most common type of cast, granular casts can result either from the breakdown of cellular casts or the inclusion of aggregates of plasma proteins (e.g., albumin) or immunoglobulin light chains. Depending on the size of inclusions, they can be classified as fine or coarse, though the distinction has no diagnostic significance. Their appearance is generally more cigar-shaped and of a higher refractive index than hyaline casts. While most often indicative of chronic renal disease, these casts, as with hyaline casts, can also be seen for a short time following strenuous exercise

Hyaline Cast

Urinary casts are tiny tube-shaped particles. Urinary casts may be made up of white blood cells, red blood cells, kidney cells, or substances such as protein or fat. The most common type of cast, hyaline casts are solidified Tamm-Horsfall mucoprotein secreted from the tubular epithelial cells of individual nephrons. Low urine flow, concentrated urine, or an acidic environment can contribute to the formation of hyaline casts, and, as such, they may be seen in normal individuals in dehydration or vigorous exercise. Hyaline casts are cylindrical and clear, with a low refractive index,

Rbc

RBCs contain hemoglobin, which carries oxygen. How much oxygen your body tissues get depends on how many RBCs you have and how well they work.

Renal Epithelial Cells (Only Reported If Detected)

Squamous Epithelial Cells

Transitional Epithelial (Only Reported If Detected)

Triple Phosphate Crystals (Only Reported If Detected)

Struvite stones (triple phosphate/magnesium ammonium phosphate) - about 10–15% of urinary calculi are composed of struvite (ammonium magnesium phosphate, NH4MgPO4·6H2O).[44] Struvite stones (also known as "infection stones", urease or triple-phosphate stones), form most often in the presence of infection by urea-splitting bacteria

Uric Acid Crystals (Only Reported If Detected)

Abnormal crystals may appear in urine as a result of pathology or due to normal catabolism

WBC

WBCs help fight infections. They are also called leukocytes. There are five major types of white blood cells: basophils, eosinophils, lymphocytes (T cells and B cells), monocytes and neutrophils

YEAST (Only Reported If Detected)

Candida is the scientific name for yeast. It is a fungus that lives almost everywhere, including in your body. Usually, your immune system keeps yeast under control. If you are sick or taking antibiotics, it can multiply and cause an infection.

  • Monitoring Chronic Conditions: In patients with diabetes, high blood pressure, or other chronic conditions that can affect kidney function.

What the Test Checks For:

The urinalysis microscopic test checks for various microscopic elements in the urine, including:

  • Cells: White blood cells (indicating inflammation or infection), red blood cells (suggestive of kidney disease or UTI), and epithelial cells (shed from the urinary tract lining).
  • Crystals: These can form in concentrated urine and may indicate conditions like kidney stones.
  • Casts: Casts are cylindrical structures formed in the kidney tubules and can indicate kidney damage or disease.
  • Bacteria: Presence of bacteria suggests a urinary tract infection.
  • Other Particles: Various particles, such as mucus, may provide additional diagnostic information.

Other Lab Tests That May Be Ordered Alongside:

When a Urinalysis Microscopic test is ordered, it's typically part of a broader assessment of kidney and urinary tract health. Here are some tests commonly ordered alongside it:

Most Common Questions About the Urinalysis Microscopic test:

Clinical Utility and Interpretation

What does the Urinalysis Microscopic test diagnose?

The Urinalysis Microscopic test examines urine under a microscope to detect and measure various cells, cellular fragments, and other microscopic components. It's primarily used to help diagnose urinary tract infections, kidney diseases, and other conditions that can cause visible and microscopic blood in the urine.

What might the presence of white blood cells in the Urinalysis Microscopic test indicate?

White blood cells (or leukocytes) in the urine, a condition known as pyuria, often suggest a urinary tract infection (UTI). They can also be present due to other conditions like kidney diseases or inflammation.

Clinical Applications and Diagnoses

How can the Urinalysis Microscopic test be useful for someone with recurrent UTIs?

For individuals with recurrent UTIs, the Urinalysis Microscopic test can help determine the presence and extent of the infection, allowing healthcare providers to adjust or change treatment plans accordingly.

Can the Urinalysis Microscopic test detect kidney stones?

Yes, the test may reveal crystals that can be indicative of kidney stones. Different types of crystals can suggest different types of kidney stones.

Comparative Insights

How does the Urinalysis Microscopic test compare to a standard urinalysis?

While a standard urinalysis includes a visual and chemical examination of the urine, the Urinalysis Microscopic test specifically examines the urine under a microscope. It provides detailed information about cells, bacteria, and other microscopic substances in the urine, offering a more in-depth analysis.

Understanding Limitations and Challenges

Are there any substances or medications that can change the results of the Urinalysis Microscopic test?

Certain medications, foods, and pigments can discolor the urine, potentially affecting the results. For instance, consuming beets or blackberries can turn urine pink or reddish, and some medications can cause the urine to turn a variety of colors.

Can the test detect all types of kidney diseases?

While the Urinalysis Microscopic test can give indications of kidney problems by showing abnormalities in the urine, it can't diagnose all types of kidney diseases. Some kidney conditions may not produce any abnormalities in urine or may require other tests for a definitive diagnosis.

Additional Questions and Insights

Why might there be red blood cells in the urine as revealed by the Urinalysis Microscopic test?

The presence of red blood cells in the urine, known as hematuria, can be caused by several conditions, including UTIs, kidney diseases, bladder or kidney stones, and more rarely, tumors of the kidney or bladder.

Is it normal to find bacteria in the Urinalysis Microscopic test results?

While a small amount of bacteria might be found due to contamination from the skin, significant amounts of bacteria in a clean-catch urine sample typically suggest a urinary tract infection.

How often should someone with a history of urinary issues get the Urinalysis Microscopic test?
