Prolonged or excessive fever would have the least effect on hematocrit percentage compared to the other options. Erythropoietin (EPO) injection stimulates red blood cell production, increasing hematocrit. Dehydration concentrates blood by reducing plasma volume, thus increasing hematocrit. Living at higher altitudes stimulates erythropoiesis due to lower oxygen levels, also increasing hematocrit. Fever, while it can affect fluid balance, does not directly influence red blood cell production or hematocrit levels to the extent of the other factors.
