Gastroenteritis DXS

Diagnosis of parasites is often based on direct detection by microscopy, which is insensitive and laborious and can lack specificity.  In fact, a significant number of IBS (irritable bowel syndrome) cases could actually be due to undiagnosed gut parasites such as Blastocystis hominis and Dientamoeba fragilis. PCR testing is a far more sensitive test than the old fashioned technique of looking through a microscope.

A GI Pathogen Panel, PCR (polymerase chain reaction) assay looks for the genetic fingerprint of a wide range of pathogens.  With its ability to detect minute amounts of DNA or RNA contained in tissues or fluids, PCR has improved the rapidity and accuracy of diagnosis, enhanced understanding of pathogenesis, and helped identify infectious causes for diseases previously considered idiopathic.

Absolute DXS uses the GI Pathogen Panel, PCR as a multiplex PCR assay for the detection of various forms of E. coli, staphylococcus aureus (also known as staph) and salmonella to help physicians accurately and quickly diagnose and treat patients suffering from complications of the digestive tract. These mainly include conditions affecting the pancreas, liver, gallbladder, esophagus, stomach, small intestine and colon.

Multiplex PCR-based assays have high sensitivity, directly detect parasites independent of the immunocompetence or previous clinical history of the patient, and can distinguish between organisms that are morphologically similar.
