    No help, no nurses or secretary. Just a cold automated unhelpful system.

    I was at quest yesterday. I got there at 9:30 AM. And then I proceeded to wait for over three hours. I am aware that as a walk-in, I was not given priority as those who had made appointments. However there were people that I spoke to that were behind me on the list that were given priority over me. I am a person with permanent and life-shortening disabilities-- I sat there for over three hours. Eventually, I had to bring up enough courage to knock on their door and ask to use the restroom. I say courage because I watched other people knock on the door to ask why things were taking so long--they were greeted with a nurse yelling at them to have a seat and that their name will be called when it is called. I was in the restroom for less than two minutes, and while in the restroom, they apparently took my name off the list. So when I returned to the lobby and took my seat. I noticed my name was no longer on the list. I then had to knock and wait at the door because there is no desk, there is only a front electronic kiosk for you to sign up at, I had to ask about my name. I was not greeted with respect or concern or empathy. Just someone yelling at me to take a seat while I was trying to explain to them how my name had been taken off the list and I was only gone for two minutes and I wasn't even number one on the list, I was second. The nurse Shouted down the hallway at the other nurses asking if they had called my name. I had been second on the list for over an hour. I was only gone two minutes, the same nurse who took me off the list is the one who showed me to the restroom. I never complained. I sat there for over three hours. I was extremely late to get back to class. I had to fast, and hadn't eaten anything for over 72 hours. All I could have was water, I just needed to use the restroom. I'm not sure if they were discriminating against me for being disabled or my age/ethnicity/sex/ect, But I did not feel that this place is a welcoming environment or operates empathetically. People are in there to have blood drawn--not for fun, but most likely because most of us are suffering from health related illnesses, you'd think they would operate more efficiently and empathetically. (I updated my previous negative review here to reflect my new google negative google review, after a THIRD awful visit.)

    Bummer! Phone lines out all over town,  so no electronic check-in ...

    Quest Diagnostic 's lab center on Loma Vista is convenient to both hospitals and the plethora of medical offices in the area. I have used their services many times. The facility is clean and light. Lots of chairs spaced along the walls. The staff are friendly, professional, and skilled. The automated check-in is quick and easy to use. Without an appointment you might wait for a bit, but with one, I am usually in and out in a half hour or so.

    My blood was taken 3 and a half weeks ago and still no results on the website (says pending). Impossible to reach a real person to complain about this at this time. I did manage to reach someone last week and they said to "wait another day or two". I am stuck and I am blaming this lab in Ventura for this because I've never had any issues with other quest labs at other locations. Also my girlfriend has dealt with this Quest lab before and said they were incompetent. I should have remembered what she told me before coming here.

    This place is a joke! No one works at the front desk and the nurses that come out calling the names lack compassion. I was there for 3 hours before I decided to leave without being seen.

    No one is at the desk

    Shit service!!! we got here at 4:08 and then they told us at 4:30 that they wouldn't be seeing us. Talked about being short staffed, well maybe if your staff weren't in the back screwing around you would actually see the patients !!!!When they were all in the back talking to 1 patient it doesn't not take 4 "doctors" if you can even call them that, to pull blood work from one person. This is by FAR the worst Quest we've ever been to. No wonder they have really bad reviews!

    In the past, when a doctor requests a blood, urine, or feces sample i have gone to another place…read morethat begins with the letter Q. I don't think I can say the name here. Q always has long waits. Yes they are shorter with appointments. it is often crowded at Q. A couple years back, my doctor said, Do you want to go to Q or Pacific Diagnostic labs? I had never heard of Pacific. I said I would try Pacific. WOW!!! This place has never had more than 3 people in the waiting room!! You do not need to make an appointment. Say what??? It is so dang convenient. The test results are super fast!!! Many of the doctors who are affiliated with CMH can see your blood results. So my gastroenterologist can check out my results as well as my endocrinologist. Easy peasy. I forgot to add my general doctor to my lab work. You can tell Pacific labs of all the doctors you want to see your test results. Pacific Diagnostic Labs are nearly perfect. I did have a couple of times when my insurance said there was a problem. I called and these 2 issues were resolved. I believe that there is only 1 or 2 people who work here. I do not know the name of the main gal. She checks you in and does the tests. She is a 1 woman show. She is always kind, friendly, & professional. I low-key do not want word to get out so this place doesn't get crowded and yet, I owe my fellow yelpers this knowledge.

    I am afraid of needles and get close to fainting after I get my blood drawn. I told my phlebotomist…read moreup front, and she was so lovely and helpful. It was literally pain-free. I still started to faint (not her fault), and she took great care of me and kept me conscious. I will absolutely go back.
