The importance of routine blood work
Benjamin Franklin said it best in 1735 when he said, “an ounce of prevention is worth a
pound of cure”. That is still true almost three centuries later. Diagnosing a problem
early means we can start corrective treatment early and help our pets live longer,
healthier lives. This is the reason your vet will talk to you about blood work even when
your pet is healthy and just in for vaccines.
Veterinary medicine is a unique branch of medicine. We rely heavily on owner’s
recollection of our patient’s clinical signs and on a thorough physical exam to diagnose
a problem. Sometimes, however, that isn’t enough because the disease process has
not advanced to the point that we have overt physical changes. Cats and dogs are
animals and as such are programmed to mask symptoms of illness. In the wild this
would be a beneficial trait, so the hunter doesn’t become the hunted. As pets that
programming is a hindrance. Many owners will miss the subtle signs of disease in their
pet or dismiss it as a behavioral change due to external sources like a change in the
season or some change in the house. Because owners do not feel the behavior change
is significant, they likely will not mention it to vet staff on their routine exam and the pet
will continue to get sicker and sicker. Far too often pets are not diagnosed with a
problem until they are very sick and it’s too late to intervene. Routine monitoring blood
work helps us detect problems early when we can do something to prevent emergency
or fatal situations from occurring down the road.
Many conditions give us subtle changes in our blood before we ever have significant
clinical signs. Hyperadrenocorticism (Cushing’s disease), Hypoadrenocorticism
(Addison’s), Protein Losing Enteropathy (PLE), kidney disease/failure, Hyperthyroidism,
gastric ulcers and splenic tumors are just a few of the conditions that will have blood
work changes before we have any outwards clinical signs of disease. Catching these
problems early can save you hundreds if not thousands of dollars in emergency vet
visits.
Monitoring blood work is not just beneficial to the older patients either. Young cats and
dogs can be born with abnormalities in their organs. They may have no outward signs
of disfunction, but their blood work will show subtle shifts in enzyme levels. Knowing
these conditions early in their life can drastically change their outcomes later down the
road.
Routine blood checks are just another piece of the puzzle that veterinarians must put
together each time a patient comes through our door. Having the whole picture helps
us treat our patients more efficiently and helps our pets stay with us longer.
