Mervin Lab doe`s not look fancy, but it is a great place. Inocencia, the lady who run`s it does her profession with her heart and a lot of knowledge. If you ask her she explains the results and give you advices what else could be usefull to look for. My friend from Germany arrived here ill and with a bag of tabletts. She just checked out from a german hospital where the reason for her health problems never were not found. I took her to Inocencia showed the german blood work and Inocencia began to investigate. Inocencia found the reason, she did the same with an other friend of mine. Al the information we missed from the doctors, she gave it to us. Because of the great personality of Inocencia, this is a great Lab.
