Yes. I mean I think as I said in my prepared comments and on the first question, too, I mean we saw a nice recovery. Obviously, there was obviously some -- a little bit of a slowdown in January. So we had a nice pickup, I'd say, in October, November where -- sorry, yes October, November, where we saw procedure growth rates return to growth. And I'd say December, January saw that decline as the cases increased, but saw real nice progression in the month of February and then very strong growth in March.
And Rob, what we try to do also is we try to look at there's -- March is a tricky month because you've got those 2 weeks of last year where things kind of really kind of shut down. So we look at March not only versus last year, but also looking at it versus March of 2019, and quite frankly, the whole quarter versus 2019. And we actually see growth rates in this quarter that are higher than our pre-pandemic rates in 2019, in Q1 of 2019. So I think we saw a real nice growth.
In Core Lab, that was very positive to see. We saw double-digit growth there, and that's a good indicator of routine testing coming back to hospitals, saw double digit there.
Our Molecular Diagnostic business, excluding COVID and PCR COVID testing, was up 30%. So that's a real positive sign that our strategy of utilizing the Alinity M to launch into the market with COVID and then kind of build off the menu is also having a positive impact over there, too.
So I'd say very good exit rate. And as we look at the first 2 weeks of April, and we look at it every week here, real nice progression.
So I didn't see the bolus coming in and then the drop. I actually saw continued nice improvement in Structural Heart, in EP and even in CRM. So those are -- that's a nice trend as we're going into the second quarter, too.
And we'll start to see a little bit of opening up here in Europe. I'd say the one area that was a little bit softer for us was Europe, given all the shutdowns there. But again, I'd say the first couple of weeks in Europe are looking pretty good.
