<cynic on>$1.80 per assay? So the doctor who takes the sample, takes his cut to pay for the smartphone and his overhead. Add $200. The lab will add on a tidy profit plus the cost of the IT equipment and personal... add another $200. The insurance company will be billed for 1.5 times that since they never pay full-price. $1.80 per assay you say? Yeah.. right. <cynic off>
On the less cynical side, this can be a good thing. Especially if the volume lets the price (to the consumer or insurance company) drop. Being "new", insurance companies will probably tag it as "experimental" and not cover any of it. But it becomes affordable even without the insurance company paying, it will be very beneficial for those who might go undiagnosed.
