Minor Thalassaemia (Beta) is the term used to describe heterozygotes
for Beta Thalassaemia (ie one normal gene, one abnormal gene). Rather
than the severe symptoms of "major" thalassaemia, minors usually cope
ok except when stressed eg during pregnancy.
Obviously light headedness can be a symptom of anaemia - although
symtoms shouldn't normally occur with a Hb of >11.
As for test reults, you would expect Hb 9-11, MCV <75, increased HbA2
as you described.
Hope this info is satisfactory.
