Just seen GP as thyroid test came back as normal even though feeling terrible. Took list of things that you recommend to have tested expecting to be told no after reading others experiences on here! Told GP I had joined support group + these tests were recommended + surprisingly he thought this was a good idea + promptly printed off a blood test form! The vit D + zinc test did not appear on the standard form but he wrote it on saying the hospital would know if they could be done. All tests have been done with no quibbles so awaiting results but would like to go armed with recommended levels.
