Hopefully the embarassment of getting tested isn't preventing anyone from getting the medical attention they need, but if it is, this company now offers STD testing software that can be used from the privacy of your own home. Based in Boston, Luminostics is developing rapid tests that can be performed with a smartphone. Their goal is to be able to provide "instant, on-demand access to molecular-level health information," which currently extends itself to STD testing, and more specifically the testing of Chlamydia.
Their smartphone device can test blood, saliva or urine samples using the camera flash. The Luminostics system is comprised of three parts: a reusable smartphone attachment, a disposable cartridge and a diagnosis-measuring app.
