Will my cat need a lab test prior to cat diagnostic imaging?

Not necessarily, but it's possible because we are trying to figure out the whole picture of what's going on. So if it's indicated, blood work like a complete blood count or chemistry might be indicated. If your pet is older, it might even include a urine test or a thyroid test for a cat. But we don't always require sedation. Lab work may or may not be required for the imaging.
