Complexation prevents the metal ions from reacting with molecules in the body, and enable them to be dissolved in blood and eliminated in urine. It should only be used in people who have a diagnosis of metal intoxication. [34] That diagnosis should be validated with tests done in appropriate biological samples. [35]
Lead enters the bloodstream through exposure and elevates blood lead level that may result in lead poisoning or an elevated blood lead level. [17] For example, a child can ingest lead by chewing on a toy that is made of lead-contaminated metal or is painted with lead-contaminated paint .
The deferoxamine challenge test is a diagnostic test for confirming iron poisoning, however it is no longer recommended for diagnostic purposes due to concerns regarding the accuracy. [3] Deferoxamine can be administered intramuscularly as a single dose where it then binds to free iron in the blood and is excreted into the urine turning it to a ...

Blood smear showing red blood cells with basophilic stippling. Basophilic stippling, also known as punctate basophilia, is the presence of numerous basophilic granules that are dispersed through the cytoplasm of erythrocytes in a peripheral blood smear. They can be demonstrated to be RNA.
The Reinsch test is an initial indicator to detect the presence of one or more of the following heavy metals in a biological sample, and is often used by toxicologists where poisoning by such metals is suspected.
Porphyrin complexes of zinc have been known since the 1930s. [1] In 1974 ZPP was identified as a major non-heme porphyrin formed in red cells as the result of lead poisoning or iron deficiency., [8] It was already known at this time that non-heme protoporphyrin IX levels were elevated in these conditions, but prior investigators had used acidic extraction methods in their assays that converted ...
