Can a staph infection present with high percent lymph in blood tests?

Yes, a staph infection can present with a high percentage of lymphocytes in blood tests, although it is more commonly associated with neutrophilia. Lymphocytosis may occur in response to the infection, depending on the individual's immune response and the specific type of staphylococcal infection. However, interpreting blood tests should always be done in conjunction with clinical symptoms and other diagnostic information.
