Thank you for submitting your question regarding Jelly. She has some mild changes such as an elevation in her lymphocytes. These are white blood cells. While this can indicate an infection or inflammation in the body, it may also be an insignificant finding for her. If she is acting normally, then I would not be concerned. If she is sick, however, then she may need this result repeated based on her recovery. I hope this information helps!
