well this just ruined my day.
is it OT? sure is........it said "test kit" right on the box.
Yup. We finally got rid of that pesky second line on Boy 3 here, all others (including me, who've been coughing for 4 weeks straight now; this is something else...) have been clean through and through. School starts Tuesday, so this is good timing.
From an on-topic perspective, the mechanics of these tests show a remarkable development over fairly short time. Now, we can do a saliva-only test in 15 minutes. That was not the case year and a half ago.
