What Blood Tests Should I Get for Mood Swings?

The most recommended blood tests for mood swings are TSH, estradiol, progesterone, vitamin D, vitamin B12, and a CBC. Thyroid dysfunction and hormonal fluctuations are leading causes of mood instability. These tests also detect nutritional deficiencies linked to rapid shifts in mood.
