    Has anyone been tested for Covid19 at this lab and if so how was your experience? I would love to know how accurate you think the results are & did you have symptoms or not? Thanks in advance

    Hello. Me and my entire family got tested here because my brother in law was experiencing symptoms. He tested positive. The rest of us were negative and did not have any symptoms. He went back to be retested after 2 weeks and he came back negative.…

    Review for Ms. Nancy Diaz and Quest Diagnostics, 2250 S. Main St., Corona, CA…read more Ms. Nancy Diaz is truly exceptional. She is caring, gentle, and very professional. Her warm and calm manner immediately puts you at ease, and she works with such confidence and skill that the entire experience feels comfortable from start to finish. I appreciated how kind she was and how she explained everything clearly. She is outstanding at what she does. This Quest location is also excellent. It is very clean, organized, and efficiently run. Because appointments are required, there is essentially no wait time. Check-in is quick, and you are seen almost immediately. The whole process is smooth and respectful of your time. Quest is very fortunate to have Ms. Nancy Diaz caring for patients at this location. I highly recommend this office.

    I have been at Quest for approximately four hours on the standby list. I completely understand that…read morepatients with appointments take priority and that being on standby means there is no guaranteed wait time. That is not my complaint. My complaint is the way Latonya treats people who do not have an appointment. She is rude, dismissive, and makes you feel like you simply do not matter because you are a standby patient. People are coming here because they need lab work done, and everyone deserves to be treated with basic courtesy and respect, appointment or not. During my four hours here, they were only calling approximately two standby patients per hour, and at one point roughly 90 minutes went by without a single standby patient being called. After waiting patiently for that long, asking a simple question about the wait should not be met with attitude. I understand being busy. I understand appointments come first. What I do not understand is treating people as though their time and concerns do not matter simply because they walked in without an appointment. Better communication and basic kindness would make a huge difference.
