A CBC counts the no. of cells present in your blood. A low or high value or an abnormal value usually indicates a range of health issues that need to be taken care of.

Abnormal CBC or ESR results can point to a variety of health issues. If your red blood cell count or hemoglobin is low, it could be a sign of anemia. If your white blood cell count is unusually high or low, that might indicate an infection, an immune system problem, or, in some cases, a blood disease. As for the ESR, a high sedimentation rate usually signals inflammation and can be seen with conditions like arthritis, autoimmune diseases, or infections.

Certainly, the normal ranges for CBC and ESR tests do differ slightly between men and women due to biological and hormonal differences. For instance, men typically have higher levels of red blood cells and haemoglobin, while women may show slightly elevated ESR values, especially during menstruation or pregnancy.
