A piece of bad news wrapped in protein

Note: This is the fourth, and last, part in the series, recently named, Who's letting who down?. The name of this part is a quote from Peter Medawar, a British immunologist, which is more famous as the miss-quote: "a piece of nucleic acid surrounded by bad news".

If there is going to be another Sherlock fic, I hope it's going to be a happier one.

Summary: At the hospital, watching Sherlock until Mycroft can get off work, John take the opportunity to run a series of tests to establish Sherlock's health status after his years of drug abuse.
