Logo for online medical services (launch product is private blood testing)

This is what 365medics (tagline: Private Blood Tests - can see with and without) was looking for in their logo design

Hi there!
I'm looking for a logo for my new business called 365medics.
I'm a GP in the UK, and my service will initially be offering a private blood testing service. (Clients will purchase a blood test, and a phlebotomist will visit them at home to take the venous blood sample.) In future, I may want to offer more medical services other than blood tests.
The logo should look professional as we are a 'serious' medical service. I like the idea of some kind of symbol, maybe a cross as this represents health but am open to suggestions.
I would be happy to explore having the tag line: 'Private Blood Tests' (I can remove this in future if we start offering other medical services.) I'm happy to see variations with and without a tag line.
I'm flexible in terms of colours. I like the idea of the '365' being a different colour to 'medics''.
Hope this is enough information but let me know if you need anything else!
