Acute blood loss

Discussion

If one were obsessive, one could also point out that the slight elevation of the eosinophil count could point to eosinophilic oesophagitis- but it could just as easily be a reaction to the transfusion of blood products.

Overall, the blood results have nothing weird in them except anaemia.
