Could a serotonin or dopamine deficiency in one's blood cause depression/anxiety? Or are the blood ser. And dop. Unrelated to the ones in brain?

In brief: Unrelated

Assays for serotonin and Dopamine in the blood are not reliable indicators of these substances in the brain's synaptic spaces.
You may be offered these assays by "independent medical thinkers", but you would not do well to rely on them. Depression and anxiety are biopsychosocial phenomena and must be addressed as more than "chemical imbalances" -- their many aspects are all important.

In brief: Weakly related.

The serotonin and Dopamine in the blood regulate different processes than the ones in the brain.
In fact, IV Dopamine is what we give to people with heart failure to make heart pump stronger.
