I've had relative lymphocytosis on every blood test for a year now + now the absolute count is a little high too. is this at all concerning?

Depends: It depends what a relative lymphocytosis meams and how high the absolute count is. Why have you have been getting blood tests? Are there other symptoms? Fevers, night sweats other symptoms? If you feel fine I would not worry too much if the counts are truly just mildly elevated. You would be wise to follow the trend over time.. Perhaps another test in 2-3 months.

Lymphocytosis: Hi, I'm wondering if anyone has done any peripheral smear? Any infectious or connective tissue work up? Although lymphocytosis is not a common side effect for Abilify (aripiprazole) but there has been some report, Your doctor could order a Flow Cytometry to make sure no blood malignancy existed although I highly doubt that.
