Interesting to see the tagline incorporated into a design! I like that idea
OUr brand character is a serious, business-like one, and the and our customer is the medical laboratory. I feel like the exclamation point would be better suited for a consumer audience
one more thing -- I really like that you are giving us an option that does not use the arcs from the ResearchDx logo. We have to think not just about the logo but other graphical elements that we will need when we create marketing materials like the website and some printed materials. Giving us some different concepts is really helpful.
