No doubt the result. The scientific interpretation is accompanied by very useful glossary.

The ease of use was a relief when you're already feeling anxious or unwell.

excellent service; walk-in without appointment, kindly greeted, blood taken without any fuss, results same day.  Absolutely faultless

My husband and I have been using Sigma for several months now and are very pleased with the condition and care Sigma takes in the preparation and delivery of their products. 

I took my disabled son for a second blood draw after quest had used the wrong tube to test how well his seizure medication was working.  When I got there they could not find the script.  The very young rec was rude and refused to call a supervisor and saled a piece of paper with customer service’s number in it .  I called and they said they would email the original script .  Her tall male coworker then came in and used his size to try and intimidate me and stated I was aggressive ( I was assertive ) when asking to have the blood draw to maintain my disabled son’s health.  He threatened me with supervisors he said he called .  My son he’s been crying and shaking ever since 

I get bloodwork May 28,2025 appt. While ordering online, it is not apparent that LabCorp on demand is different than LabCorp. On demand cannot be linked to insurance. June 3, 2025. I want to link my results to my insurance. On the LabCorp website, my billing history is blank. The screen states: if the bill does not display, provide invoice #, zipcode, birthdate, and click update insurance button. I enter my invoice number which it states it doesn't exist. The Billing screen states to call this number if you don't see your bill history, so I did. After 30+ minutes of back and forth, the person finally informs me that she needs to transfer me. I have no idea why.  The next operator was quite rude and abrupt. She kept interrupting me, telling me to stop, I was providing too much information. I was being quite direct. Essentially, she couldn't care less and had the answers before I asked them. She said I had initially called Labcorp billing, and that she is Labcorp On Demand. She continued to interrupt me. I could tell she wanted me off her phone. I said Why didn't the girl before know this right away from my issues. She kept saying I called the wrong place, didn't say goodbye, and hung up on me. How am I supposed to know the difference? My results are linked through the LabCorp website. When googling, I only see Labcorp website links. It is not apparent that these are two different departments/companies. (The On Demand website states: You can purchase your lab test without a doctor's visit—right here, right now. Just click to purchase and register your test to get started.) I did not notice that On Demand orders are different than Labcorp. Nor that ON Demand orders are not coded for insurance to be available for linking to insurance. There should be a disclaimer on all websites to make it very clear that LabCorp versus On Demand bills will never display and don't link to insurance. My initial appointment issue May 28, 2025. The waiting area was past capacity. People were complaining to everyone (shouting it out) that all appointments were over an hour behind. People with appointments were leaving without being seen. My appointment was 10:30 am. It was well after 12 when they took my blood. If LabCorp can't handle the number of people, do not allow walk-ins. In my area, Quest sticks to their appt times. People are in and out. I would research before going to Labcorp. The website is confusing. IMO LabCorp has gone downhill. I now understand why all my employers and insurance prefers Quest. 

Terrible. Understaffed and employees are leaving. Labcorp greedy company.

Do not use this company. My results were supposed to be back almost a week ago. When I call, get automated recording that keeps cutting out. Unable to submit question via chat or email - button to submit doesn’t work.
