A one-time stool sample was collected by participants in a sampling tube (Eiken Chemical Company, Tokyo, Japan) containing 2.0 mL of buffer designed to minimize hemoglobin degradation at home within 3 days before initiating bowel cleansing for colonoscopy. The collected fecal material, sealed in a plastic bag, was sent to the laboratory. Fecal hemoglobin concentration was quantitated using OC-SENSOR DIANA™ (Eiken Chemical Company), and FIT results were expressed in nanograms of hemoglobin per milliliter of buffer (ng Hb/mL). The FIT-positivity cutoff value was 100 ng Hb/mL (equivalent to 20 micrograms of hemoglobin per gram of feces).22 (link)

The Sampling tube is a laboratory equipment used for the collection and storage of samples. It is a hollow, cylindrical container made of inert materials such as glass or stainless steel. The tube is designed to hold a specific volume of sample material, allowing for accurate and consistent sample collection and preservation.

All participants collected a one-time stool sample at home, using a sampling tube (Eiken Chemical Company, Tokyo, Japan) containing 2.0 mL buffer designed to minimize hemoglobin degradation, within 3 days before initiating bowel cleansing for colonoscopy.
The collected fecal material was sent to the laboratory sealed in a plastic bag. Fecal hemoglobin quantitation was performed by using OC-SENSOR DIANA (Eiken Chemical Company). FIT results were expressed in nanograms of hemoglobin per milliliter of buffer (ng Hb/mL), and the FIT positivity cutoff value was set at 100 ng Hb/mL (equivalent to 20 μg Hb/g feces) [16 (link)].

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
