Is it considered deadly if you have a red blood cell count of 900 and it is falling everyday?

Answer 1

900 what? Normally, a person has 4-5 million red blood cells per cubic millimeter and a total number of 30,000,000,000,000 (30 trillion) RBC in the human body. So if she only has 900 cells in her body, she's in deep trouble. Usually anemia is measure by hematocrit, or hemoglobin concentration or RBC/microliter (cubic millimeter). Normal values are: Hematocrit 40-45%, hemoglobin 12-15 mg/dl, RBCs 4.5 million per cubic millimeter.
