Human blood testing is like sampling fluid deep in Space Station pipes

A new coagulometer – a simple testing thingy with a tiny sensing chamber – needs just a pin-prick's worth to analyse a patient's blood. It works using tiny micro-mechanical cantilever arms first developed to test fluid flowing in inaccessible areas – like deep inside the Space Station's cooling pipes. A UK start-up is expanding distribution worldwide, developing and selling these marvellous little devices that help patients everywhere. And less blood means less pain. Sorry, vampires.
