I don't know what LFT is, a response to Interferon.

I may have to take Interferon A for Polycythemia Vera, another disease I
have (high platelets, high red cells, in other words thick blood). I never
took any MS drugs, knowing I was drug sensitive. I may HAVE to take the
Interferon A, however. Or risk stroke.

It's getting harder being older. Now I've had several dx's: MS, Porphyria,
Polycythemia Vera. Too much.
