Your RBC count of 4.83 is only marginally above the lab's upper limit of 4.80, and your haemoglobin at 13.58 is comfortably normal. This isn't something dangerous. A reading this close to the edge of the range usually isn't clinically significant, especially since most of your other blood counts are normal too.
Next Steps
