alpha + beta Thal carrier plans to have baby with alpha Thal carrier

Thanks for the acknowledgement Gracia and Andy.

Now I know what to do. Millions of thanks for the information.

No problem Andy.  I've gone through many leagues in my quest...  For Malaysia's part I can give advice where to go, more than that, you're still the best!

I agree with Andy.  Do not take any chances.  I wish you all the best Shinji.
