What does Pb, Blood Measure?
Lead is a soft heavy metal which has a number of industrial applications because of its relatively unreactive and stable nature. It is a major component in paints, petroleum, batteries, bullets, weights, radiation shields, etc.
However, lead is highly toxic to the human body, even in small amounts. Use of lead has been discontinued in a number of applications like lead-based paints, leaded fuel, etc. Yet, significant amounts of lead are still present in our immediate environment, including the soil, food items, water, etc.
The primary ways by which lead enters the human body are through ingestion and inhalation. This is common in infants and young children who often put their hands in their mouths after playing outside in the soil. This can result in the accidental ingestion of lead. Lead exposure occurs in adults through occupational or recreational methods.
Lead is toxic even in very small amounts, causing irreversible damage to various organs of the body. In infants, lead exposure can cause permanent mental damage, causing behavioral abnormalities and impairment of mental growth without showing any other physical symptoms. Lead poisoning may occur due to ingestion or inhalation of a large amount of lead at one time or may develop slowly over a long period of time. The blood lead test is performed to measure the levels of lead in blood and to determine the extent of poisoning.
