The Etest, an antibiotic impregnated strip, has been available since the 1980s, and genetic methods such as polymerase chain reaction (PCR) testing have been available since the early 2000s. Research is ongoing into improving current methods by making them faster or more accurate, as well as developing new methods for testing, such as ...
It requires a minimum of 2 days and maximum of several weeks to culture gastrointestinal pathogens. The sensitivity (true positive) and specificity (true negative) rates for stool culture vary by pathogen, although a number of human pathogens can not be cultured. For culture-positive samples, antimicrobial resistance testing takes an additional ...
Labcorp was an early pioneer of genomic testing using polymerase chain reaction (PCR) technology at its Center for Molecular Biology and Pathology in Research Triangle Park, North Carolina, where it also performs other molecular diagnostics.
Gastrointestinal pathology (including liver, gallbladder and pancreas) is a recognized sub-specialty discipline of surgical pathology.Recognition of a sub-specialty is generally related to dedicated fellowship training offered within the subspecialty or, alternatively, to surgical pathologists with a special interest and extensive experience in gastrointestinal pathology.

Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).
Gastroenteritis, also known as infectious diarrhea, is an inflammation of the gastrointestinal tract including the stomach and intestine. [8] Symptoms may include diarrhea, vomiting, and abdominal pain. [1] Fever, lack of energy, and dehydration may also occur. [2] [3] This typically lasts less than two weeks. [8]
The standard serology panel for seroconversion include hepatitis B surface antigen, hepatitis B surface antibody for IgM and IgG, hepatitis B core antibody for IgM and IgG, and hepatitis B e-antigen. [61] In the typical disease course for hepatitis B, [62] the individual will first seroconvert for hepatitis B surface antigen (HBsAg).
