Gastrointestinal infection is the most common type of infection encountered in patient populations. These infections are not always severe but they often resolve rapidly on their own without any treatment. Gastrointestinal infections may be caused due to three main causative agents including bacteria, virus or parasites. It causes inflammation of stomach and intestines that comprises our gastrointestinal tract which leads to gastroenteritis. Some of the microorganisms that cause gastrointestinal infections are adenovirus, campylobacter, Clostridium difficile, Escherichia coli, rotavirus, salmonella and shigella and others. The major gastroenteritis symptoms include diarrhea, nausea, vomiting, occasional muscle aches or mild headache and abdominal discomfort. Out of these, diarrhea is the most dangerous gastrointestinal infection, which lowers the water content inside body and causes severe problems. A rapid diagnosis followed by appropriate treatment is required to be done in order to control gastrointestinal infections. A large number of laboratory tests and microbiological screening tests are performed to detect and confirm the presence of disease causing antigens in stool samples obtained from patients. In a laboratory testing procedure, a routine stool culture is done which begins with the primary step of specimen collection followed by processing of specimen. Stool samples are checked for the presence of reducing substances in stool and identification of pseudo membranes in the colon is done by direct visualization. However, most of the infectious diarrhea are self-limited in nature and require a primary care including oral rehydration, intravenous rehydration or antimicrobial therapy. The gastrointestinal infection testing is broadly categorized into three types including laboratory tests, imaging tests and biopsy. Also, gastrointestinal infection testing is done using conventional techniques, molecular techniques and biochemical techniques.
Growing adoption of technologically advanced molecular techniques and rising incidence of gastrointestinal infections are the primary factors driving the gastrointestinal infection testing market. Increased government funding in healthcare projects and growing trend of pharmaceutical companies to manufacture novel drugs and diagnostic techniques are some other factors fueling the market growth for gastrointestinal infection testing methods. However, lack of awareness about novel diagnostic tests and improper regulatory guidelines for laboratory testing is restraining the growth of gastrointestinal infection.
On the basis of type of gastrointestinal infection testing, stool analysis is extensively performed over other types of tests owing to its ability to assess the overall health of GIT and thereby providing more accurate results. However, molecular techniques such as a real-time PCR and Matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS) allows the lab technicians to perform high-multiplexed tests in order to diagnose gastrointestinal infection.
Based on geography, global gastrointestinal infection testing market is segmented into five key regions viz. North America, Latin America, Europe, Asia Pacific, and Middle East & Africa. Out of these, North America registered the largest shares in global gastrointestinal infection testing market and is anticipated to dominate over the forecast period on the account of growing patients suffering from abdominal pains and gastrointestinal infections. On the other hand, Asia Pacific is projected to register a highest growth during forecast period in global gastrointestinal infection testing market.
Some of the key players present in global gastrointestinal infection testing market are Savyon Diagnostics, bioMérieux India Private Limited, NanoEnTek Inc., Luminex Corporation, Hologic Inc., Bio-Rad Laboratories Inc., Becton Dickinson & Company and others.
