If you carry a thal gene you need to know because when two carriers have children, there is a 25% chance of having a thal major. There is a 50% chance of passing on thal trait to your children if you are a carrier. Our group has loads of people in it who wish they had known theirs and their partner's status before having kids. If there is any possibility of being a carrier, you should learn your status. We hear of many problems with thal minor pregnancies and reports of many miscarriages among thal minor women. I have discussed this at length in many posts. If you have had miscarriages, clotting issues or very low hemoglobin levels during pregnancy, checking your status is advised. Since you have previously been told that some of your red blood cells are not normally shaped, you should ask for the results of a CBC, which should already be in your records if you have routine physicals. Your doctor can tell you if your Hb level is low. If this is so, ask for a copy of the CBC results.
