| EAC rosette | <haematology> Rosettes formed from erythrocytes (E) coated with antibody (A) and complement (C). A test for C3b or C3bi receptors (CR1 or CR3). The rosettes form more easily then E or EA rosettes. See: E rosettes. (16 Mar 2000) |

| EA rosette | A test for the presence of Fc receptors. (18 Nov 1997) |
| E rosette | The adherence of erythrocytes to cells. Sheep erythrocytes will adhere spontaneously to human T-cells, forming rosettes. (05 Mar 2000) |
| E-rosette test | A test to identify T lymphocytes by mixing purified blood lymphocytes with serum and sheep erythrocytes; rosettes of erythrocytes form around human T lymphocytes on incubation. (05 Mar 2000) |
