I came to 90 N MacDade Blvd, Glenolden , PA, and checked in at 10:15 am and waited two hours before being called. People with appointments are called first, so during my two hours of waiting, anybody who walks in with appointment are called first regardless of waiting for hours. I really didn’t expect to be called after two hours. I had no choice but to stay for a pre-employment test. The service sucks. I do not recommend Quest Diagnostics.

Fake study about Vitamin D???? Its a joke!!!
Rating: worse than worse
Company spreads fake news about vitamin D.
Every studied immunologist can bring hundreds of counter-evidences concerning respiratory diseases.
In addition, the study authors are biased. The article, "Assessment of the Association of Vitamin D Level With SARS-CoV-2 Seropositivity Among Working-Age Adults," appeared May 21 in JAMA Network Open. There is no mention of a peer review of the paper. The probands were employees of Quest Diagnostics. The authors claim they have no conflict of interest, which is bordering on the ridiculous, since the authors report that their employer, which distributes Covid tests, not only funded the study but also edited and approved the article.
zzzz.....
All the study authors can do with the antibody tests is check whether people with higher vitamin D levels are less likely to inhale the virus. Hardly anyone claims that, however. Rather, the hypothesis that would need to be tested is whether sufficiently high vitamin D levels are helpful in allowing the body to fight off the invading viruses without getting sick or to cope with a mild course of illness. This study cannot say anything about this, because the finding of antibodies says nothing about whether the test person was (seriously) ill or "symptomlessly infected", as the non-ill patients are so nicely called nowadays.
It is recommended that the publication be withdrawn. Not that authorities still investigate here because of scientific fraud, that could be expensive in court for all injured parties, if in a few months in other, correct, publications exactly the opposite turns out and people with low vitamin D levels have almost died.

I would give them zero stars if I could!!.I am new to the area my Dr.ordered blood work she sent me to Quest.I looked online and it said walk-in wait time so I assumed you could walk -in to a Quest location WRONG!!! Went to 3 locations all turned me away and said make an appt online .Problem is appts are a week out.On top of everything else the ladies at all 3 locations were over the top rude especially at the 17th St.Ft.Lauderdale location .They refused to take me as a walk in even though there were zero people waiting in the waiting room. I have never had such a cluster trying to give blood this is our health and I think Quest needs to know how your collection centers are being ran and the people running them worst experience ever.

I had a blood test for Vit.D
I had a blood test for Vit.D done at a Greenwood location on May 20th of 2021. It was a painful procedure, and the drawing took a longer time than it normally does. I think that they got more blood than needed for a simple test. The worst thing is that I have had pain in my arm for the second day now after that test.

Very bad customer care service post the lab tests. I am waiting for my son's lab results for almost 2 weeks now. They have not shared the results with the doctor yet. When I call there office they call do not get transfered. There online chat bots are equally useless. Never ever going for any blood work there

Don't believe what they say.
Don't come here if you have less than 2 hours. Checked the wait 5 min before arriving on their website which stated 25 min wait. 1 hour & 40 min later still waiting. Their board that shows you in the queue shows I am 4 minutes to being next, except it has been that way for 21 min so far. So having electronic tools to lie only makes me hate your overpriced, useless system more. Such such
a betrayal of health services. How can I trust the integrity of the results?

OK to all of you who are upset about customer service let me explain. I worked for them 19-20 They do not allow their reps to explain tests. We could not tell someone to fast or not fast. We had to tell them to go to the location and ask someone there. They had shady practices with employees my advice is go somewhere else if you can.
