Laboratory tests are often more useful for chronic poisoning than for emergency diagnosis because of the time required to perform them. In cases of acute poisoning, immediate clinical intervention is critical, and laboratory analysis of body fluids and tissues can be too time-consuming to provide the rapid results needed for emergency treatment.1

Conversely, in chronic poisoning, the urgency of immediate life-saving measures is typically lower, allowing for the thorough analysis of biological samples. These tests help evaluate the extent of injury caused by the toxic agent over time. Furthermore, diagnosing chronic exposure often requires a comprehensive investigation into the individual's home and work environment, which complements the laboratory findings to identify the source of the poison.1
