As someone with a bit of experience in Big Data and medical technology...
A test that falsely indicated HIV 9 times out of 10 is absolutely wonderful, if it actually catches that one correct positive reliably. A false negative is far more dangerous, and it's the job of the doctor to try multiple tests to confirm a diagnosis. If the initial screening comes back positive, the patient can be warned off intercourse for a while or start some initial therapy while another test is tried, without significant risk to the patient's health.
Similarly, Big Data is just a term for a particular approach to model design. Having huge amounts of data doesn't magically improve your analysis algorithm, and you still need to have a properly-skilled expert testing your algorithm to make sure that it's correct before it's used for business decision.
