High lymphocytes are likely from infection. RBC count is only ever so slightly high and normal by most standards. Nothing to worry about. Simply being dehydrated could also cause both counts to be falsely elevated.
26, F. Slightly elevated RBC and high absolute lymphocytes.I [26,F] just got blood work done yesterday - routine chemistry and hematology tests. I weigh 120 lbs and Im 54. I do not smoke but used to vape. Everything under the routine chemistry test came back normal. My RBC shows as high (5.17). The reference range is 3.80-5.10. My lymphocytes were also high (4301 cells/mcL). The reference range for this is 850-3900 cells/mcL. My wbc, MCH, MCV, neutrophils, hemoglobin, and hematocrit are all normal.I got cbc tests done a year ago and they came back normal. I was sick all last week with either a cold or the flu. The doctor said my throat looked red. He used the stethoscope to listen to my heart and lungs and said everything sounded good. Could being sick last week cause the RBC and lymphocytes to be high? I have pretty bad health anxiety. Doctor didnt call me with the results yet but I can see them online.
