The agglutination test at the bio labs for first year students don’t allow you to see individual cells. You simply see a reaction or lack thereof. That’s a bit different from what OP was asking.

That is absolutely wrong. The immune system HAS to recognize self in order to attack the non-self. It does so mostly through two self-identification molecules (Human leukocyte antigens [HLA], and the major histocompatibility complex [MHC]). When the immune system doesn’t recognize the body’s own cells you get autoimmune diseases.
