    The phlebotomist who drew my blood yesterday was amazing!! She was so kind, professional, and…read moreskilled that I barely felt the needle. She made the experience much easier and I want to give her the biggest shoutout.. I wish I got her name..... but she was the only one working on 6/22! Based on previous visits, I expected to be in and out quickly and parked in a 30-minute spot. However, I waited over 30+ minutes to be seen, which was stressful since I didn't want to leave to add time to the meter and risk missing my turn. I was also fasting for a lab draw so I was a little hangry. And, it took about a month to get this appointment, which is much longer than I've experienced in the past. What is going on? I'm luckily healthy, but it makes me worry for those who need lab routine draws. The phlebotomist was the only staff member working, which likely contributed to the delay. She provided excellent care, but the clinic could clearly benefit from additional staffing and improved scheduling.

    Quite the inept and unprofessional company, at least in their administration. It didn't start well…read morewith their online appointment; had to book way in advance, and then when spots & times were availalble and chosen, next screen said sorry, not available. except they were. tried to book a dozen appts, all said not available until I checked my email and got notices for 10 confirmed appointments meaning I had to go back & cancel the extra ones. lame software. next, date was finally here and fasted the night before, got down to Valencia with a "Temporary Closure Notice" for renovation week of 5-24 through 6-2 on the window in the week of my confirmed appointment. did they email to alert me? NO. just a wasted trip. Reading the other poor reviews, renovation seem to be their thing. Sign recommended next closest location: Post St, NOT the closest, then below that 15th st. Went there as a walk-in. No one to greet you except an iPad. Employee hiding in her vestibule unseen, waiting to engage with the computer. If I didn't walk back, who knows how long I'd be ignored. Such a poor experience all around.

I needed labs for my pre-surgery requirements and the earliest appointment was two months away. I did a walk in at the Ocean Avenue location and the wait was four hours long and packed with people. I decided to take a chance at Noe since I was fasting, and they were able to get me in right before their 11:30 am lunch break. The sign outside says it's "appointment only" but if you check in at the machine inside and say you'll wait, they may be able to do it if not too busy. The female phlebotomist was also working the front desk and was very kind and patient. She was personable and didn't lose her cool despite the influx of patients. I really appreciate her squeezing me in. The other male worker was processing the labs in the back as they do that on site. He was hustling too. This location is much less stressful than others. Appreciate their hard work.

Prior to my scheduled appointment LabCorp sent me both reminders to my mobile #, and an online check in option. I checked in online 15 minutes prior to my appointment from my car. Then I walked over to LabCorp at 6:58am where there were 10 people ahead of me. At 7am the doors opened, and I bypassed the line and sat down. My name was called a minute later. I confirmed my information. Another minute later the phlebotomist called my name. I had blood drawn and was out under ten minutes. I still can't believe how easy this appointment was this time. Hopefully my next appointment will be just as easy here. This location is at Lakeside Village. There's metered street parking and two hour residential parking.

They send you reminders and also have an online check in link. If you go early and try for walk in appointment, there could be 20+ people with the same idea. Folks with appointment will go first based on scheduled time. Having a Labcorp account will allow LC to send you bloodwork results and analysis which you can print and save for your records.

Convenient location (on the #1 Muni Bus line). I walked in and saw a huge number of people who were seated and waiting. I checked in on the upright kiosk. Done. Then I took the initiative to speak to the woman sitting the check in desk. She was a blood draw pro herself (I know there is a special term for this). She said they take walk ins. I said I had an appointment. I got to go ahead of all those walk-ins! Huge+! I had brought in my doctor's order/paperwork (although my doctor said the order would be transmitted to Labcorp; I've learned that it's expeditious to have it on hand). Paid a co-pay. Got invited into a room. The technician took the samples. Minimal discomfort. She was a PRO! Done and out the door in less than 10 minutes! Best to have an appointment if you think you're time is valuable. Imo: LabCorp technicians will help you get in & out; you just have to set everything up right.

They didn't call me until after 2:12 to see what I needed today and copy my insurance card. I finally saw someone at 2:22 for one blood draw. That's almost an hour since I walked in. WOW I also saw people who were waitlist after me got because you can see the board got called before me. The people are nice. They're just very into their computer and the doctor's orders. Prioritize the appointments is my recommendation. Because what's the point of making one!!!!!!!!

    I had a very frustrating experience with Invitae's genetic counseling support while trying to…read morefollow up on my whole genome testing results. I reached out with specific, informed questions about my report--particularly regarding documented limitations (including areas where additional or targeted testing may still be clinically relevant). I also asked about next steps given ongoing and evolving neurologic symptoms. Instead of receiving clear guidance, I was repeatedly told to "wait" until a future specialist appointment several months away. At the same time, I was also told I could submit medical records to support updated symptoms--but no clear explanation was provided for how that process works or whether it would allow for earlier review. That inconsistency made it very difficult to understand what my actual options were. The interaction itself was also concerning. When I attempted to ask follow-up questions or clarify discrepancies between what I was being told and what was documented in my report, I was told the counselor would not "go back and forth" on the issue. The tone came across as dismissive, and it did not feel like there was room for meaningful discussion. Additionally, some statements made during the call about the scope of testing (including claims about what had been ruled out) did not appear to align with the written report I received, which further added to the confusion. Genetic testing is complex, and I understand that not every question has a simple answer. However, patients should be able to ask reasonable follow-up questions about their own results and receive clear, consistent, and respectful communication in return. I would strongly recommend that Invitae improve: * Clarity around what whole genome testing does and does not rule out * Guidance on when additional testing may be appropriate * Communication standards for patient interactions This experience made an already complex process significantly more difficult than it needed to be. Patients navigating complex conditions should not have to push this hard just to understand the limitations of their own test results.

    I used Invitae via Bon Secours for genetic cancer screening and it seemed fine. But when I went to…read moreget FH testing, I realized this is probably a scam. Think Elizabeth Holmes. They outsource FH testing to a company called "Genome Medical". My Monday consult with the genetic counselor was fine. She disclosed she was driving and I asked if she wanted to reschedule but she said she was fine. She seemed knowledgeable and I told her I was leaving the country Friday, but she assured me all as well. After the call, she told me she'd have the test kit sent via overnight shipping. Come Wednesday, nothing. I tried to call Genome Medical (the subcontractor, as far as I can tell) and I was redirected into a voicemail after a lengthy hold. I called Invitae and was told there was no order and to call Genome. Buck passing at its best. Can't wait for my bill. Genome finally called me back and I asked them to cancel the shipping of the test kit as I was not getting service or anything I was promised and that my GC was clearly too busy driving to remember the overnight commitment. They said they'd cancel. Next thing I know, there's an order. Which I missed because I wasn't in the country, like I said. No one can tell me if temps are a factor in accuracy. This is a joke. And if you're going to outsource your service, it's your job to handle your vendor. You don't get to tell me to sit on hold forever only to get routed to a voicemail. Unacceptable. And I have no recourse because Invitae just tells you goodbye.
