Yes, so we definitely feel like we've been taking share but also continuing to impact the Greenfield opportunity. So if you remember NIPT, overall, we still think is only about 15% to 20% penetrated in you know, particularly in that average risk setting where there's a lot of customers that are still ordering high risk only. So we think there's a lot of room to grow. We just did a big market survey, where we, you know, in detail, you know, mapped out, high risk, low risk where the opportunity is. And it's really incredible how many physicians are still doing high risk only and how big that opportunity is. But when you look at the uniqueness of our offering where we have - we can detect things that simply other companies can't. Nobody else is doing the snip method. Everyone's doing shotgun sequencing, there's just biological limitations, things that they can detect. And you combine that with the extensive Rolodex of peer reviewed publications that we have at this point, we are by far, the leader now in published data. In fact, just recently, we had another publication in the Green Journal, with over a million patients study that confirmed are near 100% accuracy on fetal sex determination. So we just continue to push out evidence that shows are unique aspects and physicians now recognize us, as both the clinical and market leader. Now we've combined that with a strong sales force. And an extreme focus on user experience. A lot of the customer tools that are now being used in COVID are things that we've been investing in, you know, for the past four or five years. Mobile solutions, ways physicians can interact with patients, ways we can interact with physicians, and provide counseling for patients. So we certainly see that as a major part of the business going forward. I think, you know, to the extent that mobile phlebotomy itself is important, I think that really depends on you know, what happens with COVID long term, and you know, how frequently patients are returning to their offices. But absolutely, digital tools are very important. And we've always said the user expense is extremely important.
