Are hospital blood tests stored for future examination?

A doctor once told me that when they take blood for testing, even if they don’t test for a specific disease, they can still go back and pull up more results at a later time because it’s run through a computer and all results are stored (not the actual sample). Does anyone know if this is right? I think she was talking about hospital or ER blood tests. If this is true, how would an undiagnosed patient get them to pull up more computerized results (such as blood calcium or potassium levels) from a past ER visit if they weren't looking for calcium or potassium at that time?
