Good morning, @rimmy2 You’ve done some good homework in reviewing past labs. Being able to notice trends in blood test results can be helpful for doctors to discovery any changes in the body.

Elevated lymphocytes aren’t necessarily a big concern because an up-tick can be caused by things such as a viral infection or chronic inflammation with conditions like autoimmune diseases.
But the fact that you noticed this upward trend in your husband’s blood results over the past 5 years is a good point to bring up with the NP. Blood conditions can be very slow to develop so if she doesn’t feel this is worth noting, if this were me, I’d at least push for some further testing to determine an underlying cause. General practitioners and family health NPs are not always tuned into nuances of blood changes. So if you’re not satisfied, you could go one further and request a consult with a hematologist.
Were there any other trends noticed in his blood work or any changing symptoms over the years?
