GoldSeeker: my understanding is that RECAF is related to cell division...since your body is constantly doing cell division, you will always have small levels of RECAF. in scenarios where the cell division becomes RAPID (cancer, pregnancy, etc), your RECAF levels become highly elevated. The 5k unit level seems to be the magic #.
