Flow cytometry test results as a ratio of the test result (T) compared with the control (C). Samples 8 and 9 were tested by microscopy.

†

Results from control healthy donor platelets and patient's own platelets tested in parallel, using SW16 anti-GPV as capture mAb.

‡

Average result from testing at least 3 cells previously incubated with the blood group AB control sera and patient's serum tested in parallel, using SW16 anti-GPV as capture mAb.

F1-153

Result not above cut-off of twice the control result.

F1-159

Autoantibodies were eluted from the patient's platelets and tested by MAIPA.

na, not available, archive samples referred to in the text; nt, not tested.
