They need to make stuff like this useful without a lab.
I cannot stand tests that require you to send the test in for lab testing, because they ask you for personal information and add you to their spam lists, and suddenly you start getting health and product related junk mail from everyone and their grandmother.
If they really care about letting people catch stuff like this early, make it an OTC test that provides results at home like a pregnancy test or even the covid test
I also agree with you. I don’t put my blood in the mailbox.
I see this as another tool for early detection. But there is still 17% that it may fail to detect.
The government health care always looks for the cheapest way and gets rid of other forms of detection for that reason.
