Study Notes
Urine Sample Collection Methods
- Fecal collection method is free from contamination by microorganisms and provides aseptic samples
- Rectal tubes and catheters are used to channel stool into a collection bag
- Manual bladder compression method is easy to perform, requires no sedation/anesthesia, and provides small-volume urine samples over a defined period
- However, this method is non-traumatic and the strokes should begin at the stomach level and end just beyond the bladder area, with most pressure exerted in the bladder area
Catheterisation Method
- Provides aseptic samples, but there is a risk of introducing pathogenic agents into the bladder
- Only possible in females, and there is a small risk of thrombosis
- A sterile syringe is passed through the abdominal wall into the bladder to collect the urine sample directly
Urine Collection Considerations
- Urine collection from rabbits should be as stress-free as possible
- Free-catch urine collection method provides large urine samples over a defined period, but there is a risk of contamination by microorganisms
This quiz covers the methods and processes involved in collecting urine and fecal samples from animals, including sedation and anaesthesia.
