Answer 1

Serotonin is measured on a venipuncture specimen in cases of suspected carcinoid syndrome (where it will be elevated). The normal range is 101 to 283 ng/ml.

Serotonin syndrome
Extremely high levels of serotonin can have toxic and potentially fatal effects, causing a condition known as serotonin syndrome. In practice, such toxic levels are essentially impossible to reach through an overdose of a single anti-depressant drug, but require a combination of serotonergic agents, such as an SSRI with an MAOI.[10] The intensity of the symptoms of serotonin syndrome vary over a wide spectrum, and the milder forms are seen even at non-toxic levels.[11] For example, recreational doses of MDMA (ecstasy) will generally cause such symptoms but only rarely lead to true toxicity.

Abnormally low serotonin activity in the brain has been specifically linked to intermittent explosive disorder (DSM IV), violent suicide, panic, and unrestrained aggression (rage).

Answer 2
