My current weight is 55 kg, and lately, I have been feeling weaker day by day. I am very concerned and would like to understand what the main issue in the report might be.

I have a lymphocyte percentage of 41.5, a total RBC count of 6.47, hemoglobin level of 18.6 g/dL, and a hematocrit (PCV) of 52.08 percent. All these values are above the reference range mentioned in the report. Should I be concerned about these results?
