Pre-anesthetic blood work is highly
recommended prior to surgery. Your pet cannot describe
symptoms to let us know that something may be wrong and many pets
are very good at hiding symptoms. Pre-anesthetic blood work
allows us to perform a thorough assessment to detect abnormalities
or disease conditions that may be present.
By testing blood chemistries, we
can evaluate the status of your pet's major organs. The
function of the liver and kidneys is especially important because
these organs process and excrete the body of medications used
during anesthesia. If your pet's liver and kidneys are
not functioning well, then anesthesia may be more of a risk.
In some cases, we will modify the anesthesia protocol or may
recommend postponing the procedure.
Blood work
is recommended for pets of all ages. Whether the age
of your pet is 10 months old or 10 years old, blood work will
provide valuable insight to the overall health of your pet.
It is also valuable to have baseline parameters as it allows us to
detect disease early and to monitor response to therapy, aging and
environmental changes.
The collection of a blood sample
before anesthesia or as a part of a wellness evaluation is not just
for detecting abnormalities, but also to confirm the health status
and to establish baseline values for overall health in the
future. Any changes in health can be detected when the
parameters change from baseline but remain in the normal range for
the general population. In other words, when a normal range
is established for your pet, small changes become meaningful.
Remember, your
pet is good at hiding illness and disease.
Without pre-anesthetic blood work, your pet is at a higher
risk of complication during surgery.
Illness and disease know no age boundaries. Protect your
pet.

Components of pre-surgical blood screening
CBC (complete blood count): Measures red
blood cells, white blood cells and platelets. Abnormalities in this
test could indicate anemia, infection, or blood clotting
disorders.
BUN and Creatinine: Measures the kidney's
ability to excrete waste. If values are elevated, kidney disease is
suspected.
Blood Sugar (Glucose): Elevated levels can
indicate problems such as diabetes. Low levels may be
associated with liver disease or other issues.
Total Protein and Albumin: Measures important
protein components of the blood which ensures that blood will clot
normally, liver is functioning appropriately, and that the body can
excrete the anesthesia efficiently.
ALP and ALT: Elevations can indicate
liver disease or endocrine disorders such as thyroid disease,
diabetes, Cushing's disease or Addison's disease.
