How long should it take to get Entyvio levels & antibodies?

I did the bloodwork last Thursday, early afternoon, and the technician said it would take 24 - 48 hrs. It's been longer and I have my infusion tomorrow. I am wondering if there's any chance I'll actually get it before the infusion. It is being done by Labcorp.

Really depends on the lab and network. I haven't used labcorp in a few years, but pretty sure they (along with most labs these days) have an app/website you can sign into and get alerts as soon as your test results are available. That way you know asap when the results are available.

However, I'd just get your infusion as scheduled and not worry. If your levels are low, then your doctor might increase the frequency of your entyvio infusions (from 8-week intervals to 6-weeks as an example).
