d-dimer, t-PA, fibrinogen, and PAI-1 are actually more accurately described as measures of fibrinolysis - which I believe is abnormal in ME much more often than coagulation. (The latter is the formation of clots, the former is their degradation - both can present clinically with a bleeding diathesis, but the former is usually milder.)
I think you might be abnormal on thes as you match me on a lot of other things (low CO2, very low ESR, POTS, swollen veins in my feet / lower legs, acute onset, age of onset, etc.
Reduced fibrinogen is likely the cause of your low ESR, which is a result of hyperfibrinolysis degrading fibrin very rapidly. It's sort of a low grade DIC.
