The Aluminum (Al) Level test using Atomic Absorption Spectrophotometry (AAS) in both flame and Graphite Furnace Atomic Absorption (GFA) modes is a laboratory test used to determine the concentration of aluminum in various samples, such as blood or water. This test is highly accurate and capable of detecting aluminum levels, helping assess exposure to this metal in industrial or environmental settings. It is important in public health, toxicology, and environmental studies, as it aids in making decisions based on reliable data.
