Yelp review for IHDLab

"Ashley... was not personable and very abrupt with her communication. Then when she drew my blood she stabbed me with the needle very hard and my arm is currently very bruised."

Birdeye review for Quest Diagnostics (Costa Mesa)

"The bummer is that these Dr's are wonderful, but what they bill for their services is egregious and deceptive... they'll take your co pay upfront and then you'll get a bill for hundreds if not thousands of dollars without anyone saying a word."
