i'm sorry that i'm not sure what you're asking. the only way a person can have their hemoglobin level checked is by a laboratory blood test. if you're referring to your hemoglobin blood test you should call your doctor because 7. 7 is a low reading. however all physicians are notified by the lab of "critical values " which means all life-threatening results are called to the doctor. if you haven't heard anything from the health care provider who ordered your lab work then you definitely should call him or her. however you do not necessarily need to go to the emergency room. if you're referring to the hemoglobin a1c test which is a measure of blood glucose (sugar) control 7. 7 would be a high reading. again this does not mean you need to go to the emergency room. however it does mean you need to follow up with your doctor. i hope this helps!
should someone go to the hospital if their hemoglobin is 7. 7?
