We have a long time member who put up a spreadsheet format
for testing for PN.
She did this a long time ago. It is designed for posters here,
to use as a diagnostic aid when visiting their own doctor.
This helps the doctor see trends and avoid duplicate testing and also to perhaps test using less commonly known criteria.
The protocols for testing to find a cause of PN are complex and not all doctors know them.

This is a site she had someone make for her, so she could share the testing sheets, to enable each person to track their own
testing at their doctor(s). This poster does not keep any data, and only offers the platform testing sheets to be used privately.
