When we suggest pre-surgical bloodwork, it’s not an “extra” just for the sake of it — it’s one of the best tools we have to keep your pet safe under anesthesia.
Think of bloodwork like a little sneak peek at how your pet’s body is doing on the inside. Even pets who seem perfectly healthy on the outside can have things going on that we can’t see just by looking at them.
Before anesthesia, we’re mainly checking how important organs are working — especially the liver and kidneys. These organs help process medications and anesthesia drugs. If they aren’t working at full strength, we may need to adjust drug choices, fluid support, or monitoring to make things safer for your pet.
We’re also looking at things like:
- Red blood cells – Do they have enough to carry oxygen through the body?
- White blood cells – Is there any sign of infection or inflammation?
- Platelets – Do they have what they need for normal blood clotting?
For younger pets, bloodwork is often just a safety check. For senior pets, it becomes even more important. As pets age, their bodies can change quietly. Kidney disease, liver changes, and other conditions are much more common in older dogs and cats — and sometimes there are no obvious signs at home yet.
Catching something early doesn’t always mean canceling the procedure. Often, it just means we can make adjustments, give extra fluids, change medications, or monitor more closely. That little bit of information can make a big difference in how smoothly anesthesia goes.
At the end of the day, our goal is the same as yours: a safe procedure and a smooth recovery. Pre-surgical bloodwork helps us plan anesthesia specifically for your pet, not just “a typical patient.”
