I use BEST LAB in Riberas. They have comprehensive services. Professional, and personable. Their prices are the best I have paid after using many different labs over the past 12 years. They do home visits when necessary. Results are sent via email if you want and are always done when promised. Gabby and Fransisco go out of their way to be helpful. I wish I never needed to use a lab, but since I do, I am very happy they are easy to find, easy to work with, and easy on my bank account.
