What happens if rbc is high and also esr value is high what it indictes?

Need workup: Sed rate is never worth a workup unless there's symptoms / signs. High RBC's -- WAY above the top of the reference range -- suggests thal minor if hemoglobin / hematocrit are okay / lowish, one of the polycythemias if they are also high. These in turn can be due to anything from p vera rubra to sleep apnea to a high-affinity hemoglobin to COPD to a right-to-left heart shunt.
