    We have been going to this Quest branch since El Portal G St Quest is being remodeled…read more They have professional staff , courteous & accommodating:) thank you for your services! All Quest laboratories we go have exceeded their excellent services ( so far ) the place is clean & they definitely observe Covid precautions!

    If you wish to have no customer service then by all means go here. You are greeted by computers…read moreonly, no receptionist. My 86 year-old husband navigated this system unsuccessfully and someone did evidently help him finally. But we were unable to download the blood test results because someone input his birthdate incorrectly (which would have been someone else other than him as he is not computer competent, nor can he see or hear very well). So I attemped to get a copy from Quest (in Merced). After waiting too long, (20-30 minutes) to speak to a human, I had to interupt one of the staff that was ignoring me when collecting other patients. They do not have a recepitionist! They claim to lack access to results. So, she handed me a card with a phone number so that I could call to get the birhtdate changed online which meant another 30 minutes or more of my time to correct an err we did not make. Still do not have the results. I chose to spend my time looking for a more humane service. I refuse to accept my husband or myself being treated like a cyphers (One having no influence or value; a nonentity)! The Management should be ashamed of implementing such inhumane delivery methods.
