If you do go ahead, I think it would be imperative that, as you mention, you get your Alhambra tickets with an afternoon time slot to the Nasrid Palace. For comparison, we did such a day trip, but from Nerja (much closer to Granada than is Marbella).
A high reticulocyte count with low RBCs, low hemoglobin, and low hematocrit (anemia) may indicate conditions such as: Bleeding: If an individual bleeds (hemorrhage), then the number of reticulocytes will rise a few days later in an attempt to compensate for the red cell loss.
The normal fraction of reticulocytes in the blood depends on the clinical situation but is usually 0.5% to 2.5% in adults and 2% to 6% in infants. A reticulocyte percentage that is higher than normal can be a sign of anemia, but this depends on the health of a person's bone marrow. Calculating the reticulocyte production index is an important step in understanding whether or not the reticulocyte count is appropriate to the situation.
