Cadmium (Cd) Level, by Atomic Absorption Spectrophotometer Flame and GFA mode is a laboratory test used to measure the concentration of cadmium in biological samples such as blood or urine. Cadmium is a heavy metal that can cause negative health effects when exposure levels are elevated. This analysis is performed to assess levels of cadmium exposure, whether from environmental, occupational, or dietary sources. It is particularly used in cases of suspected poisoning or symptoms related to heavy metal exposure, such as chronic fatigue or kidney problems. By determining cadmium levels, physicians can make evidence-based treatment decisions, helping protect public health and guide medical care effectively.
