and if you draw the blood yourself with butterfly needles and vacutainers from
allegro medical, you still need a centrifuge for the serum and pipettes for the dilution and a sterile protein solution as diluent. btw they will not see that it is diluted. a serum that has no or a low anti hbsab inside can also be used as diluent.
But the lab will not accept a sample unless ordered by a doctor and sent by a blood draw station, i assume. Maybe you can find a doc who will help you.
