What is microscopic examination of urine?
The microscopic exam is performed on urine sediment – urine that has been centrifuged to concentrate the substances in it at the bottom of a tube. The fluid at the top of the tube is then discarded and the drops of fluid remaining are examined under a microscope.
How significant is microscopic examination of urine during urinalysis?
Urinalysis may provide evidence of significant renal disease in asymptomatic patients. The microscopic urinalysis is vital to making diagnoses in many asymptomatic cases, including urinary tract infection, urinary tract tumors, occult glomerulonephritis, and interstitial nephritis.
What is the normal range of pus cells in urine?
Urine Routine Test Normal Values
| Reference range | Interpretation |
|---|---|
| Squamous epithelial cells | ≤15-20 squamous epithelial cells/hpf |
| Pus cells | 2 to 3 pus cells/hpf |
| Crystals | Acid urine |
| Casts | 0-5 hyaline casts/lpf (hyaline casts per low power field) |
What is the aim of urine microscopy?
This test looks at a sample of your urine under a microscope. It can see cells from your urinary tract, blood cells, crystals, bacteria, parasites, and cells from tumors. This test is often used to confirm the findings of other tests or add information to a diagnosis.
Is it normal to have pus cells in urine?
White blood cells (pus cells) are signs of infection. Bilirubin is a waste product from the breakdown of old red blood cells. It is normally removed from the blood by the liver. Its presence in the urine may be a sign of liver disease.
What is meant by microscopy?
Microscopy: The examination of minute objects by means of a microscope, an instrument which provides an enlarged image of an object not visible with the naked eye. Electron microscopy — Microscopy in which an electron beam replaces light to form the image.
What is the normal level of pus cells in urine?
What is the normal number of pus cells in urine?
The normal range of pus cells in urine is 0-5/hpf , however up to 10 pus cells may be present without any definite infection. If you have any symptoms of a urine infection, you should get a urine culture done.
What is the purpose of microscopy?
A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.
What is microscopy used for?
Microscopy is the technical field of using microscopes to view samples & objects that cannot be seen with the unaided eye (objects that are not within the resolution range of the normal eye).
