Cyberchondriacs and armchair diagnosticians, this one's for you.
Do you spend hours scouring medical websites? Do you pass your time watching medical TV shows and making careful mental notes about every disease they mention? Do you offer free diagnoses to every friend, family member and fellow elevator-rider who sniffles in your vicinity? Well, then it's time for you to put your expertise to the test.
We've put together a quiz featuring the common symptoms of various diseases, syndromes, phenomena and other medical conditions - some familiar, some more obscure - and all you have to do is tell us which disease is a match to that group of symptoms. So roll up the sleeves on that imaginary lab coat of yours and get started.
