how many people reported to have changed they blood due to an infection "like malaria" or bone blood tissue transplant and how that could be related to other sintomes like cancer!!?!

according to an international lab and many internet user reports...

1- "by developing antibodies and antigens they could change the result of the test ...
temporarily or also by mistake error... "

and now since summer 2018

you can also turn any incompatible blood from type A B AB to universal doner O blood now!

don't worry:
bether to use sea water or any alternative than someone's blood or plasma...

specialy
if your A B AB
and if you have memory or health issius there are statistics that say you have a higher risk...
***a virus can change your blood group test... ***

I'm kind a worried about some of the people I met once... long time ago... witch I never fully understand those viral behavior...

there could be mistakes an changes in blood tests..

could they have been infected with a virus!?
the same that cause cancer and problems some of their relatives... ?

leading to a change to AB blood group since this is also the higer risc group the one that canot be donated to other's
but only receives? "don't want to call narcissist to someone!"? lool
how many AB's are really AB's and not fake or temporary AB's???
