clinical definition of lithium level
Lithium test analyses the quantities of lithium found in the blood in order to ascertain whether drug concentrations are in the therapeutic range or need moderation and alterations. It is normally ordered whilst monitoring treatment of a bipolar disorder. Bipolar disorders are a mental condition that are characterized by alternating periods of depression and mania. Lithium is utilized as a mood stabilizing drug. Upon ingestion lithium interacts with various neurotransmitters and receptors, lowering the secretion of norepinephrine and increasing serotonin synthesis. Lithium quantities are assesed as blood levels must be maintained within a narrow therapeutic range. Excess of lithium leads to lithium toxicity and develops symptoms such as nausea, vomiting, confusion, tremors and with insufficient amounts the medications might not be effective.
