Microscopic urinalysis requires only a relatively inexpensive light microscope. Large Wait 2 Minutes - Expected result: Specific gravity measures the kidney's ability to concentrate or dilute urine in relation to plasma.

Summary To summarize, a properly collected clean-catch, midstream urine after cleansing of the urethral meatus is adequate for complete urinalysis.

Small increases in protein in urine usually are not a cause for concern, but larger amounts may indicate a kidney problem. Urine Specific Gravity tests are widely used by medics, nurses and other health professionals to screen for water-loss dehydration and measures of the concentration, or specific gravity, of concentrated particles are in your urine.

Calcium in Urine Test

A colony count may also be done to see if significant numbers of bacteria are present. Why do I need a calcium in urine test?

Record the time. Views Read Edit View history. The factors which favor protein cast formation are low flow rate, high salt concentration, and low pH, all of which favor protein denaturation and precipitation, particularly that of the Tamm-Horsfall protein.

Dipsticks detect protein by production of color with an indicator dye, Bromphenol blue, which is most sensitive to albumin but detects globulins and Bence-Jones protein poorly. Return the sample container to your health provider's office or the laboratory as instructed.

That's no surprise. In fact, these specimens generally suffice even for urine culture. Pathologists can perform special microscopic evaluations of urine to look for cancer cells.

Bartonella is a type bacteria that can be transmitted to cats, dogs and humans from exposure to infected fleas and…. When cellular casts remain in the nephron for some time before they are flushed into the bladder urine, the cells may degenerate to become a coarsely granular cast, later a finely granular cast, and ultimately, a waxy cast.

If another method of urine collection such as using a urinary catheter or collecting the sample directly from the bladder using a syringe is necessary, your veterinary staff will take precautions to ensure that your pet is not harmed.

It is important to talk with your doctor about the best time of day to perform the urine glucose test, and whether to do it before or after eating. Most patients with normal results of the tests for microscopic and visible hematuria remain well, but some don't.

Although some patients with this type of microscopic hematuria turn out to have serious kidney disease, most have mild problems such as IgA nephropathy deposits of an immune protein on the glomeruli or thin basement membrane disease a mild abnormality of glomerular structure.

A cotton sponge soaked with benzalkonium hydrochloride is useful and non-irritating for this purpose. To summarize, a properly collected clean-catch, midstream urine after cleansing of the urethral meatus is adequate for complete urinalysis. A positive nitrite test indicates that bacteria may be present in significant numbers in urine.

Urine tests Laboratory techniques. Red blood cells may stick together and form red blood cell casts. Although it's important to look for these clues, they are usually absent — so let's start considering the causes and evaluation of hematuria with the most common variation on the theme, microscopic hematuria without symptoms.
