You have included some blood results for RBC, MCV and MCH. Looking them, although you have not included units, I am concerned about the possibility of anaemia.
Anaemia can be related to a number of reasons including iron deficiency, vitamin B12 or folate deficiency (although MCV not high enough to suggest this) and alcohol intake amongst other problems.
Before you adjust your synthroid you need to discuss these results with your doctor. Some blood problems are autoimmune related and this can be linked to thyroid problems. Further blood tests will be required to identify serum iron, ferritin and transferrin saturation to rule out iron deficiency anaemia.
Does this answer your question?
