Hi and welcome to HCM. These are nonspecific findings which indiacte that there is any kind of infection in body, most common respiratory or urinary. You didnt say the exact values and his symptoms so it is hard to evaluate significancy of these results. This also can be pneumonia
reccurence,but I suggest to wait and see will hie develop some respiratory symptoms and repeat blood tests in a 4-5 days. This will show you is there any improvement and is treatment neccessary. WIsh you good health.
