Labcorp for the win! Which major diagnostic vendor you use (labcorp, quest, etc) unfortunately is likely dependent on what your medical insurance covers. I've used competitors with my past health insurance plans and I have to say my experience with Labcorp has always been absolutely stellar!! Phlebotomist are always great, you barely feel a thing when they collect a sample of blood. Due to pandemic Labcorp does what many other clinics do and have you check in from the comfort of your car using your smartphone.
