The Widal test is one method that may be used to help make a presumptive diagnosis of enteric fever, also known as typhoid fever. Although the test is no longer commonly performed in the United States or other developed countries, it is still in use in many emerging nations where enteric fever is endemic and limited resources require the use of rapid, affordable testing alternatives. While the method is easy to perform, concerns remain about the reliability of the Widal test. It is not specific for typhoid fever and can be positive when a person does not have the infection.Enteric fever is a life-threatening illness caused by infection with the bacterium Salmonella enterica serotype Typhi (S. typhi), usually transmitted through food and drinks contaminated with fecal matter. It is associated with symptoms that include high fever, fatigue, headache, abdominal pain, diarrhea or constipation, weight loss, and a rash known as "rose spots." Early diagnosis and treatment are important because serious complications, including severe intestinal bleeding or perforation, can develop within a few weeks.Zinc protoporphyrin (ZPP) is primarily ordered to help detect iron deficiency in children and to detect and monitor chronic exposure to lead in adults.ZPP is a substance that is normally found in small amounts in red blood cells. Most of the protoporphyrin in red blood cells combines with iron to form heme, the molecule in hemoglobin that carries oxygen. Zinc combines with protoporphyrin instead of iron when there is insufficient iron available to form heme, as in iron deficiency, or when lead is present and blocks the formation of heme, as in lead poisoning. The level of ZPP in the blood will rise with these conditions.
