In the good old days, a pregnancy test not only required a visit to your doctor’s office but also involved a long wait time for lab results. Now, a pregnancy test can be done anywhere there is a bathroom, with the highly accurate results returned to you in all of two minutes. These simple stick tests, though, are just the tip of the iceberg when it comes to medical test that can be done without ever leaving your home. It's a growing trend with many at-home diagnostic and monitoring tests currently available... and plenty more to come.
