If I could give zero stars I would. I will start by saying, “I’m a certified phlebotomist .” My family and I had the misfortune of having to deal with this completely unreliable lab. It’s extremely difficult to schedule to begin with and then they offer an 8 hour window for a 2 minute procedure in which they never show up for with zero communication. This time is the final straw. Appointment scheduled 3 days in a row & still are waiting!! Completely incompetent!

MS Diagnostic Laboratory sent a bill in my husband’s name when he never received services. July 2025 I was told my balance was paid in full and now they are sending me another bill. All billing calls go overseas so the communication is horrible.
