    Still getting 50% failure rate at point of transferring drops to test kit... the liquid is in the tube but once I tip it nothing will come out, then it is like the liquid has evaporated.

    I remember why I quit science lab stuff now.

  • No failure since I started squeezing the tube to squeeze the swab on the way out. At the ridges seems less likely to crack the tube.

    I've always done this. Fuck knows why half don't work. It must be error on my part but I can't find a difference between when they work vs not.
