A pre-anaesthetic blood test is a test routinely performed prior to a procedure to ensure your pet is healthy enough to undergo a general anaesthetic or sedation.
Why is this recommended?
While your pet might look fit and healthy on the outside,
Pre-anaesthetic blood tests provide us with a detailed snapshot of
What organs are you checking?
The kidneys and liver are the two major organs involved in
metabolizing and excreting anaesthetic drugs. We test the function of
these by assessing tissue-specific enzymes that circulate in the blood.
If these organs are not functioning optimally, we may see an elevation
in one or more enzymes.
Pre-anaesthetic blood tests can detect even small abnormalities prior to surgery, thus allowing us to alter our anaesthetic protocol accordingly for your pet. A range of disease processes can be responsible for elevating tissue enzymes, including infection, degeneration, congenital abnormalities, toxic damage or age-specific problems, and if found, elevations can then be investigated if required.
A pre-anaesthetic blood screen will also check your pet’s red and white blood cells and platelets. Platelets are cells in the bloodstream primarily involved in the clotting mechanism, and it’s very important we know your pet has an adequate number prior to surgery as there may be some bleeding (from skin and subcutaneous tissues) during surgery.
What does a pre-anaesthetic blood test involve?
A small amount of blood (approx. 2 ml) is collected from a vein – usually one of the veins in the neck. In dogs and cats we clip a small amount of hair (about 3cm x 3cm) to help visualise the vein and then clean away any dirt on the skin. The test is run in-house and we’ll contact you with the results prior to surgery. If requested, we can also provide a copy of the results for your own records. If you would like a copy, please ask the nurse at your discharge appointment.
Does my pet have to have a pre-anaesthetic blood test?
If your pet is 7 years or older and has not had a general blood test within the last 6 months, your pet must have the test to ensure their organs are healthy and able to metabolise the anaesthtic agent effectively.
What is the cost?
The cost of a pre-anaesthetic blood test is $104.95 and includes a red and white blood cell count with platelets, a 6 panel biochemistry screen, and a urine test.
