Franklin Roosevelt: Lab Slip Showing Anemia |
||
| anemia from hemorrhoids | In May 1941, FDR had severe iron deficiency anemia. His hemoglobin level was 4.5g/100ml, apparently due to bleeding hemorrhoids. The anemia responded quickly to therapy with ferrous sulfate. Interestingly, there were no cardiac symptoms at the time. [2] The lab slip showing this result survives. |

The lab slip shown below is from the Roosevelt Library. The President's physician, Dr. Ross T. McIntire, used a laughably transparent pseudonym for his patient.
![]() The white blood cell count ("W.B.C.") is not reduced, suggesting (but not proving) the anemia was not due to bone marrow failure. At first Dr. Zebra thought there was a dissociation between the hemoglobin level ("Hgb" on the lab slip) and the hematocrit ("Grams %"). The former measures the amount of hemoglobin protein in the blood. Hematocrit measures the amount of space in the blood that is occupied by red blood cells. Normally the hematocrit is three times the value of the hemoglobin, but the lab slip shows the hematocrit as SEVEN times larger than the hemoglobin. Examination of other lab slips discloses that the "Grams %" is not really a hematocrit measurement. It is more like "percentage of normal hemoglobin level." Thus, even though McIntire requested a hematocrit number, he was not given one. From the red blood cell count and the hemoglobin, it should be possible to calculate a mean corpuscular hemoglobin concentration (MCHC). Image courtesy of Dr. Steven Lamazow. [7] |
