The fecal immunochemical test (FIT) is a diagnostic technique that examines stool samples for traces of non-visible blood, which could potentially indicate conditions including bowel cancer. [1] Symptoms which could be caused by bowel cancer and suggest a FIT include a change in bowel habit, anaemia , unexplained weight loss, and abdominal pain .

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).
The main advantage of qualitative fit test methods is the low cost of equipment, while their main drawback is their modest precision, and that they cannot be used to test tight-fitting respirators that are intended for use in atmospheres that exceed 10 PEL (due to the low sensitivity). To reduce the risk of choosing a respirator with poor fit ...
Fit testing with extensive instructions was found to enhance workers’ protection against noise following the test and training sessions, while training with only simple instructions did not significantly improve personal attenuation ratings over the absence of instructions. Thus, fit testing system effectiveness may vary depending on the type ...

Many point-of-care test systems are realized as easy-to-use membrane-based test strips, often enclosed by a plastic test cassette. [2] This concept often is realized in test systems for detecting pathogens, the most common being COVID-19 rapid tests. Very recently such test systems for rheumatology diagnostics have been developed, too. [12]
