EOS I think is Eosinophil...and Im not sure if I have heard of EOS ABSOLUTE but I have heard of absolute blood cell count which is a measurement of the total number of the white blood cell subtypes such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils, based on the percentage of each blood cell type and the total white blood cell count...
EGFR If I remember correctly is epidermal growth factor
