I think it's safe to say that the blood Jo brings is not hers( even if she claims it is). I don't think she is even type B-ve but I would hazard a guess that BM or BD are. That blood is probably the blood that was originally in storage but was deliberately hidden. Blood has a limited shelf life and also needs to be stored under special conditions otherwise it spoils. My question is was the blood that was hidden taken out of the special storage facility to hide it or was it still kept under the special storage conditions? If Narmada slapped Imlie for real I want the doctors to turn around to Jo and say, "Oops, sorry your blood has been too long out of the special conditions and has spoiled. It can't be used now. Come donate more." Of course she can't so Imlie and Madhav's man would then be able to donate. Everyone else especially Jo and Narmada would then have egg on their faces.
