My oncologist is good about getting all the lab orders in plenty early. I finally figured out if I get my CT scan before the blood work, I can have them fill all the vials when they stick me for the IV. Saves me a wait in the lab line on my way out, and another needle. Last follow-up was abdominal CT with lung x-rays, and I was out and on my way in less than 45 minutes. Always try to get the 8:30 AM appointment.
