So...Gail...what tests have you had to identify PN?

Any?

There are specific tests that reveal various things. Some are
autoimmune, some are vitamin deficiency, some are DNA errors, some are diabetic, etc. What tests have you had, if any?
When you get your tests:
check for TSH (thyroid dysfunction)
Check ANA and other Ig proteins- MGUS
Check for low B12 and low D... B12 should be higher than 400 and make your doctor tell you the numbers. US ranges are typically too low..
Check HbA1C and fasting glucose.

Do you get vaccines? Which vaccines have you had in the last 4 yrs.
Did you get H1N1 during the fake epidemic?

Are you exposed to lots of dry cleaned clothes. Paint strippers, or
gardening pesticides?
