    I am 75 years old and am a class 2 diabetic. When younger and pre diabetic I regularly donated blood. My blood type is O positive. I was given a special donor card and when I asked why was told that I had negative antigens and my donation was broken down into parts. Don’t understand if I have O positive blood why I have negative antigens in my blood?

    Can you explain this to me.

    I am O- with an Rh Factor. Everything they’ve written here about me – is true! I’m 63, female – with hypothyroidism and a very overactive immune system. Actually, I’m about to be tested for fibromyalgia. Also, I look at wheat and I gain 10lbs! Maybe had I known all of this earlier in life – I wouldn’t be battling weight and shingles after never having gotten chickenpox. In fact, I’ve never had ANY childhood diseases – with 10 siblings. I thought I was bionic……….but, I’m simply an 0- with Rh. Damn!!! There goes my terminal uniquism!

    Hi I’m 0 neg 69 years I have been with several people who were tested positive for covid 19, some became seriously ill each time taken the precautionary measure to have the pcr test which was always negative, my belief is that if your immune system is in good order then automatically your body creates antibodies to stop any infection.
    My grand childeren some have been infected with out symptoms Please explain thank you

    I am 31 and O- and lightly researching these things. As a child I was the “sickly” one, constipation problems, fainting – vasa vegal syncope, pneumonia and bronchitis frequently. I have had joint pain since about 7 years old and come to find out have been suffering from early onset rheumatoid arthritis and possibly early onset dementia. However, in the past 3 years I haven’t even had the sniffles and hoping my memory problems are due only from my high stress. Anyways thanks for sharing, I just wanted to put out there what I’ve dealt with and if O- might have anything to do with these matters.

      I have many of these issues as well.

    I am 63 with O- blood and an RH factor. If anything – I’ve been the healthiest woman alive. Never get sick and always share my blood with those in need.

    I find it strikingly odd that some need to focus more on their own such-is-life rather than aknowledge what they have to offer humanity. Kinda sounds like a mask issue. or – as they say…..the “right” not to wear a mask as nobody else really matters much to some anyway

      That means your O positive

    I’ve seen 2 people say they are O negative with an th factor.. I get it your in your 60s and they didn’t teach this type of stuff in school. RH simple means positive or negative. So for example I’m O negative blood which means RH is negative. Now if your O positive than your RH positive. You can’t be O negative and an RH factor meaning rh positive.
