Test Category: Specialist Biochemistry
Investigation Name:Mercury -Blood

Alias or Abbreviation:Hg
Accreditation:UKAS ISO15189: 2022 accredited test: On scope
Intro:
Mercury is a non-essential element with industrial uses including the manufacture of batteries and, to a lesser extent nowadays, of thermometers and barometers. In some parts of the world it is used for the reclamation of gold from ores or spent jewellery.It is still employed as a component of dental amalgam, although there is little evidence that it poses any health risk in this use. Theories linking the presence of ethyl mercury in vaccines to autism have not been substantiated. Deliberate overdoses by self-injection of elemental mercury or by ingestion of mercury salts are seen periodically. Excessive consumption of foods such as swordfish or tuna can lead to chronic organic mercury overload.
Whole blood is the specimen of choice for the investigation of exposure to organic mercury. Where there is acute to mercury vapour or ingestion of mercury salts, it is useful to collect both blood and urine samples.
