It is possible to determine a patient's financial status by studying the chemical in the blood.
A recent study has found that there is a build up of different kinds of chemicals in people's bodies depending upon their socioeconomic status.
Chemicals related to smoking were found among the poorer lot and levels of some other chemicals was found in the rich. For instance, levels of a chemical found in the sunscreen lotion were found to be higher in those who enjoyed affluent lifestyles.
Also, the rich lot who could afford to have a diet of fish and shell fish were found to have higher levels of Mercury and arsenic in their blood.
Jessica Tyrell, team leader of the research said, "We have shown that chemicals do accumulate in everybody, but importantly the type of chemical is dependent on your wealth. We found the build up of 18 chemicals were closely linked to socioeconomic status. The accumulation of these chemicals is dependent on your lifestyle. In individuals of lower socioeconomic status, we saw smoking was particularly important in determining lead and cadmium levels."
