Hi Black Swan,
Sharmin is one hundred percent right,you are definitely not a thal major,so there is no need to panic,u might be a thal minor which in most of the people go unnoticed for whole their lives,you know when me and my mother came to know we were thal minors ,when my daughter was diagnosed with thal major,i was 23 years old at that time, and my mom was like something 45 plus,so we didn't even know that there was something wrong with us,as Andy advised you,do this test called hb electrophoresis,and everything will be clear.
