Hello, Welcome to HCM, I am Dr. Das.
Firstly, who told you that CBC indicates presence of thalassemia?
It is wrong. Whatever is the CBC report, you should do a HPLC test. It will definitely show the scenario.
Secondly, for your general information, apart from thalassemia, there are many abnormal hemoglobin
patterns which are also harmful
So, both of you should undergo a HPLC test.
