I've recently had this blood test due to suspected invasive fungal infections. I had been taking antifungal drugs (itraconazole, fluconazole, terbinafine) for quite a long time and only stopped a few days before have the test I think this has affected the result which is lower than the cut off point which is 80 ie the level that confirms fungal infection. My result was 68. From what I understand normal levels are about 15 also that it can two weeks to clear the system of these antifungal drugs. Does anyone have any ideas of what to do?
