Atomic absorption spectroscopy (AAS) is a laboratory technique utilized to measure the concentration of specific metals and metalloids present in various body fluids and tissues. This method operates on the principle of light absorption, where optical radiation is used to detect free atoms in their gaseous state. By quantifying the amount of light absorbed by these atoms, AAS provides precise measurements of the elements being analyzed. This technique is particularly valuable in clinical settings for assessing exposure to potentially toxic chemical compounds, which can have significant implications for patient health. The types of samples that can be analyzed using atomic absorption spectroscopy include whole blood, plasma, urine, saliva, semen, as well as various tissues such as brain, liver, and muscle. Each of these samples can provide critical information regarding the presence and concentration of harmful substances, aiding in diagnosis and treatment planning.
