Hi hellokelli,
Minors do often drop to the Hb 8 range during pregnancy and sometimes do require a transfusion or two during the pregnancy, and since the temporary OB won't do anything, is it possible to contact your regular OB and ask that a hematologist be consulted? The OB is not a hematologist and knows nothing about thal, and isn't willing to do anything other than wait, and 7.5 is pretty low and most women will be transfused once it drops below 8. It may be that it did drop from the kidney stones and may rebound, but again, the OB is not trained to in the matter, so a referral seems appropriate. Because the hemoglobin level is somewhat distorted during pregnancy because there is an increase in plasma volume, the Hb level cannot be considered totally accurate and will measure below what it actually is as relates to the amount of red blood cells, it is something of a gray area and a hematologist would be best to make that decision about transfusion, keeping into account that the typical method of raising Hb during pregnancy, iron supplements, will not help. Does your insurance provider require a referral before you see a hematologist?
