But they didn't take ferritin but previous tests have been 350-400

Tsh 1.8 and serum free t4 level 10 pmol/L

Also lower end of red blood cell count red blood cell count 4.36 10*12/L
hemoglobin 137 g/L
mean corpsulclar volume 95.9 fL

Previous test showed high b12 and low folate levels, but wondering if b12 could be a false reading and its actually low ?

Previous test before that was Iron 26.3
Transferritin 1.8
Transaturation 58%
Ferritin 389

What direction? Stop eating all red meats and liver ?
