  This lab has been redone and it’s very nice. Everything is clean and new. As usual staff is always nice. Check in is very easy and I was taken at my appointment time. Quick and easy experience.

  I always go to Quest Diagnostics in Sayville for my yearly blood test. They are always prompt and call me in at my appointment time, if not before, if I am early. The lab is so clean and free from any clutter. The technicians are unfailing polite, professional, and friendly. Highly recommend them for any needed tests.

  My technician, Laticia, was the best blook drawer ever.

  The Sayville office is fantastic. I had an 8:20am appointment, arrived at 8:15 and signed in via the text I had received. I was finished and back in my car at 8:24am. That is great customer service 👏.
