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

I am on Actermra for Scleritis and have 10 for my hemoglobin level, is that too low to do next infusion and when too low and need transfusion?

Hemoglobin level: Most centers will not transfuse a stable non bleeding patient with a hemoglobin over 7. Speak with your doctor if you are having symptoms due to anemia. I know Acterma can cause decreased platelets and WBC but I did not know it caused anemia too. Speak with your doctor. ...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

How can you treat persistent low hemoglobin counts following chemotherapy, other than blood transfusion?

How can you treat persistent low hemoglobin counts following chemotherapy, other than blood transfusion?

Not many: Your heme-onc dr is an expert in this, and should have discussed (or tried) a gmcsf injection to stimulate your body's red blood cell production. But, many cancer pts do not respond to it--either due to the nature of the cancer or the treatment or both. If not amenable to induction of production, then will need transfusion every so many weeks. I see many pts who do this, and once used to it are ok. ...Read more

I had a blood transfusion due to low hemoglobin. My iron level was 6 and is now 9 after two units. I still feel weak and really tired after 3 days?

Of course you do: You are still seriously anemic. Be proactive. Insist on an explanation of how you got this sick and what wil be done to restore you to health. If you have a bleeding stomach ulcer, what will be done? If you have hemolysis, what is the cause? G6PD status? Were you malnourished? You deserve a full explanation. ...Read more

What's the question?: I'm sorry dad is sick. He may have a hemolytic anemia that is causing his jaundice, or he may have liver disease and bleeding due to this or some other cause. I hope that a treatable cause is found, and if there are other questions that you have, please write us. ...Read more
