I was just looking at some of my old labs and the Elastace levels may not be directly indicative of a response to bacterial infections (not sure where I got that idea). It appears my doc was using it more to rule out other diseases. "In CFS the level of Elastase correlates with the fragmentation of RnaseL protien to a high degree, whereas in both MS and RA, this correlation is not evident". My Elastace and RnaseL both were extremely high before AV Tx. With Tx, they both dropped way down but not into normal. Most other Immune values that had been extremely high (ie, Il 6 >8000, etc), came into normal levels.
