Tests like this have always been done in the doctor's office because they're hard to perform. Samples have to be precisely measured and mixed, filtered and treated with different reagents. Unless you have a PhD in biochemistry, it's generally not the kind of thing you'd want to do at home.
But our KnowNow products are powered by mechanical microfluidics systems (think tiny gnomes with PhDs in biochemistry) that do all those steps for you.
The system is designed so you can just add the sample and slide it closed. Minutes later you get your results and can get on with your life.
