My quest experience was exceptional. No-nonsense blood draw had me in and out in 10 mins. I hate going there so this was a plus. After the good start, my results also came in very quickly. So great experience with the speed.

I have been very impressed by how comprehensive blood tests were as well clinical notes relating to the results. I would have also done the baseline MRI but I have to wait until next April after one year cancer free.
