Just back from seeing GP regarding how bad i'm feeling.
My nigh on opening gambit was ' i don't think this is depression'.
In a very jumbled way i explained how i was feeling and had a list of my symptoms...
...i won't say he didn't listen...but he was very keen to discuss further bl**dy depression.
Anyway...i made it clear i wanted to check my thyroid and b12. I did ask for a full thyroid blood test and i have to do a fasting test...for grey purple and gold container....i have no idea what that means!
Any thoughts??

Sometimes, even if GP requests (T3) the lab might not do it if TSH is in range (which is ridiculous). B12 is a necessity as is Vit d (both prohormones).
If he mentions he cannot do FT4 and FT3 say you need both and I'll give you a link to read about these too. Also say as you think I am depressed it is probably due to not having sufficient T3 circulating as my brain has the most T3 receptor cells. If I don't have sufficient !!!!!!
So that's why FT4 and FT3 are important. T3 drives the metabolism.
Different transport, storage, and processing times can be associated with different tests so can be distinguished by various colours. There's a guide here (probably more complete ones elsewhere but I don't recall them): uhb.nhs.uk/GpSpecimenGuides...
The colours refer to any mediums or chemicals that are in the test tubes to mix with the blood depending on the test required etc. For example heparin is used to stop the blood clotting in the tube.
