Murwillumbah Veterinary Clinic, Your Pet, & Pre-Anaesthetic Testing

10% off all blood tests at Murwillumbah Vet Clinic during April

Prior to every anaesthetic a vet will preform a physical examination of your pet. The focus of this exam is to detect any underlying issues, particularly of the heart and lungs, which will change the safety of the anaesthesia. Unfortunately, there are numerous common condition including kidney and blood disorders which cannot be detected without blood testing. To ensure the safety of your pet we recommend pre-anaesthetic blood testing for any animal undergoing anaesthetic, regardless of age. 

When you chose pre-anaesthetic testing you are helping to ensure your pet has a safe anaesthetic. The testing is done at Murwillumbah Veterinary Clinic and takes just 10-15 minutes and 2ml of blood.

Top four reasons to test your pet before anaesthetic

  1. Enjoy peace of mind of knowing your pet has a significantly reduced medical risk because of the knowledge the test gives your vet.
  2. Detect hidden illness which healthy looking pets may be hiding, most pets will only show they are sick late in disease. 
  3. Reduce risks and consequences of anaesthetic if the test is abnormal, as the vet can alter the anaesthetic, intravenous fluids, and pain relief medications used to make the procedure as safe as possible. 
  4. Protect your pets future health. These tests become part of your pet's medical record. Even normal tests are very valuable as they provide a baseline "normal" for your pet, allowing subtle diseases to be detected early for better outcomes in the future.

Does Pre-Anasethetic testing tell the Vet everything?

The pre-anaesthetic profile is a screening test. If your pet has abnormalities in any of these 7 markers we may discuss the need for further testing to diagnose or stage your pets illness. Commonly requested additional tests are urinalysis, complete blood counts, electrolytes, cardiac enzymes, and thyroid levels - but these will be chosen based on your pets specific results.

What is tested in a Pre-Anaesthetic Profile?


Pack Cell Volume (PCV) This is a measure of the red blood cells in circulation. Red blood cells are essential for oxygen transport, and even a mild anaemia affects the safety of anaesthesia.

Total Protein (TP) The level of TP can indicate a variety of conditions, including dehydration, inflammation and disease of the liver, kidney or intestines.

Creatinine (CREA) Creatinine is a byproduct of muscle metabolism which is excreted by the kidneys. Elevated levels can indicate kidney disease, urinary tract obstruction or dehydration.

Blood Urea Nitrogen (BUN) BUN is produced by the liver and excreted by the kidneys. Abnormally high levels can indicate kidney disease or dehydration, and low levels can indicate liver disease.

Aminotransferase (ALT) An enzyme that is elevated with liver cell injury.

Alkaline Phosphatase (ALKP) An enzyme present in multiple tissues, including the liver and bone. Elevated levels can indicate liver disese, cushings syndrome, or medication issues. 

Blood Glucose (GLU) High levels can indicate diabetes. Low levels can indicate liver disease, tumours, and infection.


Answers to the two most common "buts" we hear...

"But...My puppy is healthy, it doesn't need testing."  Your puppy may look healthy, your puppy may be normal on physical examination by the vet, but many problems are "occult" or "unseen" in young animals..yet they are still there. Some of these are congenital or inherited, some are infectious. Early treatment makes a real difference, and may prevent your pets untimely death or severe complications during a routine surgery, such as desexing, simply because we did not know the problem existed.

"But..Olivia had a blood test last year." Blood tests are a snap shot of how the body is functioning at that time. A month is a long time in the body, infections can come and go, kidney disease can manifest. If Olivia had blood tests last year, the pre-anaesthetic testing will actually give your vet much more information because the results can be compared and subtle changes detected.
