Help or Assist to decipher reduction

[Inquiring]

Tell or Say, please, that mean abbreviations (or reductions?) SIN and SIS in results of an immunogram
For example: CD95 (on lymphocytes) - percent or interest 10, 1 - the comment 2 sin
HLA-DR (on lymphocytes) - percent or interest 15,0 - the comment 3 sis

In advance thanks
