What is surveillance screening and why does my pet need it?

Surveillance screening is a fancy way of describing doing lab tests when your pet isn't obviously sick. There are a few reasons why doing appropriate tests in a pet that seems healthy is a very good idea.

Cats may hide or sleep more when they aren't feeling well.  Since they sleep a lot normally, it can be tricky to tell if something is amiss.First, our pets can't speak, they cannot tell us if they feel off color or a bit unwell or have any other indicators of internal illness. We need to examine them every 6 months as well as run some routine screening tests to detect underlying disease BEFORE it is clinically apparent. There are MANY diseases that are treatable or easily managed if they are caught early but which are much more serious if detected after your pet is sick.

Secondly, pets will actively hide signs of illness until late in the course of disease. This is a leftover survival instinct from the days of living in the wild, in a pack or colony situation.

Dogs that love to run and play will continue to do so even when sick, as long as they can.Third, even a normal result is valuable.  Normal lab work tells us what YOUR pet's normal is, so that we have something to compare with if later lab work is questionable.

Use the age chart below to find your pet's age in "people" years and the screening testing recommended for each stage of his or her life.

We believe the following tests give us the best chance of helping your pet's live longer, healthier lives.

These are approximations and may vary by gender, species and breed. Please feel free to discuss with us the best way to work together to keep your pet healthy and happy for the longest possible time.
