Liver enzymes are high in me 4 year old?

My 4 year old daughter had gone to the doctor for some blood work today because they think that she might have mumps (how I don’t know because she is up to date on all her shots and vaccinations) but anyways I came home and the doctor had called me and told me that everything looked ok but her liver enzymes were kinda high . They were 237 . They said it could be that its a viral infection that she could be fighting but they said that the mumps test wouldn’t come back for another 5 days. So now im not only worried about that but now her results for her liver enzymes have me really upset and not to mention worried. Do you think that it could be a viral infection that’s causing her levels to be elevated?
