We have written on a number of occasions how it is becoming more common for medical devices to be used at home, instead of in the hospital or clinic. That trend appears to be occurring in the lab test area as well. Here is a story about a company developing a device that will allow patients at home to draw a blood sample and send it safely to a lab for testing.
Though this is not really testing at home, it indicates where we are heading. With the many advances we are seeing in microfluidics and other testing/analysis techniques, I believe we will see in the near future many simple devices that will allow lab tests to be accurately conducted by patients themselves in their own homes, much as home pregnancy tests are done today. It will be critical to incorporate good design into such devices so they can be used confidently and competently by untrained people. This will be a great opportunity for medical device designers and product developers.
