^*Bold type indicates significantly increased percentage of leucocyte subset.

^†Blank data-test not performed due to insufficient sample. Expression of CD69 on NK cells is the most sensitive marker for infection (13 of 16 patients show significantly increased levels). Expression of CD25 and tissue factor (TF) on monocytes, are the least sensitive markers of infection.
