Blood tests: Screening tests for immune function include antibody levels, a blood count with a breakdown of the cells and measurement of complement. If those are all normal, then your immune system is probably ok.

Nutrition, exercise: If you keep your body fit through good nutrition and a regular exercise program, your immune system will likely function better. The only supplement which may help regulate the immune system is vitamin d3 , so make sure that you have an adequate intake. Folic acid has also been touted but the evidence is weaker.

Low immunity: It is commonly called that and a lot of "stuff" is sold to boost it (notice no before and after tests to prove anything). Actually altered immunity is common and likely seen with allergic individuals. Selective deficiency of the immune system do exist but are less common.

Infection & cancer: Your immune system works by recognizing when stuff in your body is different from you. Then it gets rid of that stuff. Such foreign stuff includes pathogens that cause infections like bacteria & viruses & normal cells that mutate into cancerous ones. So signs of a weak immune system are recurrent infection - usually respiratory or gastrointestinal - & decreased surveillance of cancerous changes.
