Verification of the Storage Stability of Fecal Hemoglobin in Stool Sampling Bottle Using Improved Buffer - A Pilot Study -
Objective: The temperature and duration of sample storage is known to affect the accuracy of the fecal immunochemical test (FIT). This study compared an improved stool collection buffer with the conventional buffer on the fecal hemoglobin (Hb) correlation and high-temperature stability and simultaneously evaluated the stability of fecal transferrin (Tf) and fecal calprotectin (FC).
