Lithium Level Test - More Information
The lithium test, sometimes known as a lithium blood test, lithium level test and lithium lab test, measures the lithium blood level.
Lithium, sometimes known as lithium salts or lithium compounds, is an oral medication used in psychiatry Lithium is specifically used to treat mood and manic-depressive affective disorders such as bipolar disorder and refractory major depression.
Regular lithium blood level testing is essential for people who take lithium medications to ensure that lithium levels are within a therapeutic range in the body. Low lithium blood levels might mean that the medication dosage is too low and potentially should be changed in consultation with one's medical provider. Initial symptoms of high lithium blood levels include increased thirst and urination (due to lithium's effects on sodium and water balance in the body) as well as tremors. If lithium levels get too high, it can cause lithium toxicity (poisoning) which can cause a variety of neurological and gastrointestinal symptoms, muscle twitching and kidney failure. Long-term, lithium carbonate use is also associated with hypothyroidism and elevated TSH levels which is why it is sometimes ordered with the TSH test.
