Urinalysis

In certain diseases, it is sometimes necessary to examine an animal's urine.

Urinalysis is composed of several different stages. A portion is placed onto a urinary biochemistry stick. Information about the pH of the urine, presence and amount of protein, blood, glucose, ketones and other compounds is gathered from this test.

After the biochemical tests have been completed, a refractometer is used to determine the specific gravity of the urine. This allows us to tell if the kidneys are working to keep the urine concentrated or not, or whether any other disease might be causing the urine to be inappropriately dilute.

Finally, the urine is centrifuged and the sediment is examined under a microscope.  We determine if any crystals are present in the urine (There are a number of different types of crystals that animals can develop). We also check to see whether cells, casts or bacteria are present. This information helps us build up a picture of exactly what is going on in your pet's urinary tract.

Obtaining a Urine Sample from your Pet

Many clients find this task quite difficult, so we hope the following information will be of assistance next time your Vet asks you to collect a sample.

Our canine buddies are generally not as privacy-seeking as our feline friends but none-the-less you need to be readily armed and quick!

The most accurate pathology results are from a midstream sample, collected into a sterilised container and delivered to the hospital within 2 hours of collecting. If you are unable to bring directly to us for testing, check that the lid is on tightly, then wrap the container in a plastic bag, and place it in the refrigerator. It is of further assistance to us if you can advise what time the sample was collected and a minimum amount of 10mLs is required for testing.
