Companion Animal Urinalysis and Culture

Urinalysis is a vital component in the diagnosis of diseases of the urinary system. It may also be used to rule out the presence of diseases in other body systems. There are 4 tests which are included in urinalysis:
1. Urine Specific Gravity
This is a measure of the kidneys ability to concentrate urine. Dehydrated animals with normal renal function should produce urine with a high specific gravity while animals with kidney disease may lose the ability to concentrate or dilute urine.
2. Urine Dipstick
Urine dipstick is used to determine the pH of the urine sample to detect the presence of some chemical constituents of urine such as bilirubin, glucose, haemoglobin, ketones and protein.
3. Urine Microscopy
Microscopy is used to examine the sediment of a spun urine sample to detect and identify host cells, crystals and other structures which may be present in the sediment.
4. Urine Culture
Urine culture is carried out to identify the bacteria present in a urine sample and to identify the antimicrobials to which these bacteria are susceptible.
