    Don't come without an appointment; you'll be waiting in vain.

    Terrible service you can never ever get a hold of someone to make an appointment and once you do when you get there the only give you a few minutes or they will cancel your appointment, and then you have to wait for an hour or two, also it seems when you get there no one wants to give you any information, this woman with her hair painted in blonde half of her head is completely rude and unprofessional and not helpful, she was sarcastic and mean to me, she shouldn’t try to touch anyone for blood test I will be afraid for someone like her to be even near me terrible service and I will never ever recommend this place to anyone 😡

    The worst Quest I ever been to, very slow staff that not welcomed the walk ins at all, they kept calling the appointments only and when I ask why you're not calling the walk-in, she told me I can leave if I'm in a rush!!! Shame
