No. This is genetically determined, you can't change your genes.

your blood type doesnt change, you are born with one and you keep it for life. There are hower, cases where a person has a different type of Rh factor in their blood that others (the + or -) It's rare, but some people are borderline positive or negative. My blootype for instance is A-+ it just means that my rh factor is unspecified and that sometimes i test positive, but other times it doesnt show up. It's very confusing and hard to explain. Your best bet is to google borderline rh factor.

I've heard of some people (but this is so damned RARE) called CHIMAERA where they may have sex organs for both male and female, or usually have a line where one side is darker than the other side... well, if you take a blood sample from these and you take a scrapping from their mouth, they will seem to be two separate people insofar as their genetic make-up. But that is so rare... but, to actually CHANGE blood types from positive to negative (or negative to positive)...? I've never heard of that. Perhaps someone is mistaken.
This chromosome anomaly occurs often with male calico and tortoiseshell cats and moreso if they're fully fertile! (That's why almost ALL calico and tortoiseshell cats are females... 10,000 to 1; and out of 30,000 males, maybe one is fertile!)

No way. Someone has made a mistake somewhere along the line. You should get it double checked. Good luck. It is very important to know for sure what your blood type is.

No. Rh factors are the same now as they were from the moment blood started pumping through your veins.

no, you are born with your blood type. It can never change

Unless the lab screwed in the first place with previous results., the answer is No.

the "+" or "-" is called the rh factor and it in reference to whether or not you have a particular protien. this is genetically determined and does not change.
