It always seemed like a really cool gig as I've talked to a Labcorp pilot and someone who flew the Bloodvan. It's a lot of night time and IFR and if you can handle that I think it will open up a ton of doors honestly, but for what they pay for what I believe is 4 days of flying a week is around 90k. If you have to ride out a slowdown you can do much worse for the times they're looking for.
Also I think you'd be surprised by how big their fleets are. I periodically check them and Quest Diagnostics who you might be confusing them with and I have rarely seen certain bases open since they upped their pay. I know not too many folks are lining up to living in Reading, PA, which is the one that was usually open, but even the last of Quest's pilot positions are full.
