Any information on labs that measure urine pyrroles? I know GPL has a test, but I had read somewhere not to do morning urine sample. I am having a hard time finding good information on the topic. Thank you!
Todd,
Look into a person by the name of Trudy Scott. She is a nutritionist that does a lot of work with pyrrole issues. I have done some testing, but not extensively. The pyrroles do affect zinc and vitamin B6 status though.
Vitamin Diagnostics has a pyrrole test and Doctors Data as well.
