Hi Kurahee,
I have been following this discussion with a great deal of interest, mainly as I don’t know my “family history”. I was adopted, and my biological father is unknown. Have I wondered about him at times? Most certainly, but only in the idle musings type of way, I have never cared enough to actually try and do anything about it. I did meet my biological mother when I was around 22 - got a slight family medical history then, at least enough to know that no major risk factors run in HER side of the family.
As to the question you are seeking an answer to, while I’m not a doctor, the sort of biological diseases that are carried by the father are extraordinarily rare. These did not figure in my decision to become a father (of a very precosious 19 month old who is my “monkey princess”), however I do believe that the significant ones can be tested for quite easily with a sample from YOU.
As to things like heart disease, mental illness etc, are you trying to say that, if for example, you found schizophrenia ran in the family you wouldn’t have children? I don’t mean to sound antagnositc or anything but this strikes me as being somewhat absurd, children cannot, and should not be “geneticl perfections” (ala Gattica). Just get on with the job of having them and take the good with the bad.
When my wife was pregnant one of the hardest decisions we had to make in the first tri-mester was whether or not to test for downs syndrome. Not for the risk factors but because we simply didn’t want to be faced with the sort of decision that a positive test would force upon us. When you have children you “takes what you gets” - be it good or bad.
I suspect that the decision to want your father tested is more for your own “emotional needs” than any health requirements. Given this perhaps you would be better coming to peace with yourself than pursuing any form of tests or such.
At the end of the day, whether you feel your father is a good father figure or not, whether he is worthy of your support or not, whether you want to honour him or not is a moot point, he is the only father you now have, and are ever likely to know. If you never want to speak to him, that is a decision only you can make.
I know that in my case, whether I were to find my biological father or not, I only ever know, and will ever acknowledge one “dad”. Admittedly this could be because I have a good relationship with him, but “biology” should never come into it.
I guess what I am trying to say is that you need to examine your reasons for wanting “the test” very very carefully, personally I can’t accept that they are medical in nature, and if they are emotional in nature I think a much better course is to come to peace with yourself than to cause this sort of “shit storm” and negative emotion by trying to force a test.
Even if a test can be done without anybody knowing (and this should be quite easy) I think that for you, the results are going to be a “let down”, and not really settle any issues for you emotionally, regardless of the outcome.
Having said all this, I wish you well, and do feel a great deal of empathy for you family situation, I couldn’t imagine being treated like that by my family and the hole it would leave in my life.
