I contacted the lab that tested my Nagalase levels (www.europeanlaboratory.nl), to ask them if my test result(0.7= normal) was correct. Until now, it looks like I'm the only one testing normal on Nagalase. Note however, that I received already 27(full dose) injections of Gc-Maf at that time. This is what the biologist answered me, and might of interest for all who tested on Nagalase: "Recently, we have changed the requirements in order to ensure reliable results of Nagalase testing: you should be off meds, 5 days prior to the test." In my personal case, I was 6 days off Gc-Maf when I did the test, so my test results seems reliable. Supplements like B2,B6,B12 and folic acid don't seem to influence the test. All in all, I'm thinking of repeating the test in the (very) near future. OS.
