Is serum blood test reliable for testing minerals and vitamins deficity? I did hair analyze and serum blood test. Serum blood test showed opposite picture than hair analyze. I am not sure how should I test selenium. I am taking 200mcg of selenium per day but I read that it can make risk for cancer if you have it too much. Is there any other better method?

I thought iodine deficiency was relatively common, particularly if you avoid iodized salt. This shows 15% in reproductive aged US women http://www.ncbi.nlm.nih.gov/pubmed/18053275 Here's international info and an overview http://emedicine.medscape.com/article/122714-overview
Selenium deficiency is relatively rare except in China where the soils are low. Selenium testing seems to be a bit unsettled, science wise http://www.ncbi.nlm.nih.gov/pubmed/19420095

Why are you taking selenium? Is your diet short? Why not strive to add selenium-rich foods to your diet? Only 15% of folks miss the mark on selenium, and it's one of the narrowest doses between minimum and maximum (selnium, although essential, is toxic in higher doses.)
