Lithium (Li)in hair.
The analysis of lithium levels in hair allows assessment of the long-term intake of this trace element and helps identify possible deficiency or excessive accumulation. The test is used for a comprehensive evaluation of the body's elemental status and for monitoring the impact of environmental factors.
Lithium is naturally present in small amounts in water, food products, and human tissues. It is involved in a number of biochemical processes related to nervous system function and metabolism. Changes in lithium levels may be associated with dietary habits, environmental conditions, or the use of medications containing this element.
The test is recommended as part of a comprehensive assessment of the body's trace element composition, for monitoring exposure to environmental factors, and for evaluating lithium levels in individuals receiving lithium-based medications as prescribed by a physician.
The analysis is performed using a hair sample examined by high-precision chromatography. Hair is an informative biological material for assessing the long-term accumulation of trace elements, as it reflects their intake into the body over several months.
The results help physicians evaluate the characteristics of trace element metabolism and, if necessary, recommend additional examinations or further guidance.
No special preparation is usually required for this test.
