How low can hemoglobin go before you need a transfusion?

How low can hemoglobin go before you need a transfusion?

It depends...: What's the cause? How quickly has the hemoglobin dropped/is there any ongoing bleeding? Is there evidence of inadequate tissue perfusion? What other acute & chronic medical problems does the patient have? In critically ill patients who aren't bleeding, a hemoglobin as low as 7 g/dl is generally well tolerated. Decision to transfuse should be based on desired physiologic effect, not on a number. ...Read more

Iron deficiency....: It sounds like you have iron-deficiency anemia. With a hemoglobin of 13.7, it is relatively mild at this time but still needs to be diagnosed. Have you had a colonoscopy? Microscopic blood loss from the GI tract can present like this. Colon polyps or even colon cancer can result in iron deficiency anemia. These conditions are very treatable, even curable, if caught early so see a GI doctor asap! ...Read more

Very low hemoglobin after transfusion for postpartum hemorrhage?

What is the question: Hello fbruno6. If you are still bleeding, your hemoglobin may remain low. Continued transfusions, if needed, will bring up the hemoglobin. You may also have underlying iron deficiency and that also needs to be treated. I am not sure of what your question is, but hope that the above information is helpful to you. ...Read more

How low must hemoglobin be to get transfusion?

Low: Due to the potential side-effects and risks of transfusion and the chronic blood shortage the us has, most would agree that transfusion should occur only if the hemoglobin is less than 8gm/dl (normal 12-16) or at any level if the patient is symptomatic or if there is significant active bleeding. ...Read more
