How low can hemoglobin go before you need a transfusion?

It depends...

Blood_transfusion
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.

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

Not many

Blood
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

Hemoglobin 13.7 Low iron .Need to be concern? What's problem. Not bleeding. Anemic before w/ transfusons.Transfusions again. Iron level from the labs MCV or MVC. My Hematologist was concerned. Ideas?

Iron deficiency....

Iron
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!

How low must hemoglobin be to get transfusion?

Low

Transfusions
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.

Very low hemoglobin after transfusion for postpartum hemorrhage?

What is the question

Blood_transfusion
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.

My dad has jaundice and low hemoglobin (was a 4). got a transfusion saturday which brought the levels u?

What's the question?

Yellow_skin_
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.

Im a 22 year old female and I already had a blood transfusion because of my very low hemoglobin... what should I do to keep my hemoglobin level up?

More info needed

White_blood_cell_count
You must have a talk with your physician to find out why you have low hemoglobin---excess menstrual bleeding? blood in bowel movements? nosebleeds? well-rounded diet? medications? Good luck.

I have hemoglobin E. Can I get blood transfusion if I need it?

Need more info

Blood
you don't state if you are a Hemoglobin EE or E trait or a combination with beta thalassemia. Patients with these illnesses can have anemia, often severe. The treatment is blood transfusions and they will temporarily correct the anemia.

At what hemoglobin level will I need a transfusion?

No definite level

Blood_type
This is a complex question. We would need to know what is the patient's problem . If there is no immediate surgical issue, then transfusions are given if there are symptoms like chest pain. If there is blood loss during surgery, then indications are different. At our hospital, the medical staff has said there should be no transfusions unless the hemoglobin less than 8 gm/dl.
