The Zirconium (Zr) Level, Hair, by Atomic Absorption Spectrophotometer Flame and GFA Mode test is a laboratory procedure used to measure the levels of zirconium in a hair sample. Zirconium is a metal used in various industries, and individuals may be exposed to it through work environments that contain this metal or through the use of products that contain it. A hair sample is collected and analyzed using advanced techniques such as flame atomic absorption spectrometry and Graphite Furnace Atomic Absorption (GFA) analysis. This test helps assess chronic exposure to zirconium, which may have potential health effects. The results are used to determine the extent of an individual's exposure to this metal and guide treatment options if necessary. This test is a valuable tool in environmental medicine and health risk assessment related to exposure to heavy metals.
