Generally this goes like that:

You must have 38 and 138: 38 bright expression

Also:

56: usually positive in malignant clone, can be positive on normal plasma cells, and negative on malignant cells, thus you need kappa and lambda for clonality

45: In atypical cells, very weak positivity, weak positive on normal plasma cells, positive or negative on malign cells

19: Negative on malign cells, positive on normal plasma cells

kappa and lambda for clonality

For prognosis: 117,28 and 81: 28 and 81 bad prognosis. 117 alone is fair prognosis.

As a result a gating with 38/138 and 45 will be OK, but may change based on an individual patient.
