Calprotectin blood test for belly infections after surgery

This study looks at a protein in stool called calprotectin, which can show inflammation in the gut. It compares levels in people infected with certain parasites, those with gut symptoms but no parasites, and healthy volunteers to see if it helps identify infection-related inflammation.

This trial tests a new stool test to measure calprotectin levels, which could help doctors tell the difference between inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). If you have symptoms like stomach pain, diarrhea, or weight loss and are about to have a colonoscopy, you may be able to join.

This trial tests whether a simple blood test (the capillary leak index) can help doctors better predict how sepsis will progress in people recovering from abdominal surgery. If you are in the ICU after surgery for an abdominal infection, this study may help guide your care.

This study checks whether a simple blood test for C-reactive protein (CRP) can help doctors spot a leak early after intestinal surgery. A leak is a serious complication where the repaired area opens up, and early detection may lead to quicker treatment and better recovery.

This study looks for ways to better predict and catch infections after major abdominal cancer surgery. If you are having surgery for certain cancers (esophagus, stomach, pancreas, liver, bile ducts, colon, or rectum), the researchers will check your blood and other samples for early signs of infection so they can start treatment sooner.

This study looks at how certain blood markers (nucleosome and CTCF) clear from the body in people with colorectal cancer that has spread to the lining of the belly. It also includes people with other conditions to compare. The goal is to learn more about these markers to help guide treatment.
