New Diagnostic Techniques - is Dr House obsolete?

Medical science has begun to advance dramatically in the field of DNA sequencing. This is the ability to analyze the blood of a sick patient for foreign DNA and then comparing it with a database to determine what infection the patient has.

In a case report, there was a patient with an immune deficiency who had been ill for two weeks. His blood was sent for the experimental DNA sequencing, and the infectious agent was identified.

This will eventually become inexpensive and commonplace, so that diagnosis of unusual infections will become easy.
