Diagnostic efficacy of fecal calprotectin combined with a high-sensitivity quantitative fecal immunochemical test for colorectal tumors

Figure 3 Distribution differences in left-sided colon, right-sided colon, and rectum. A: High-sensitivity quantitative fecal immunochemical test (hs-qFIT). Hs-qFIT levels were 1222 ng/mL (9-185.2 ng/mL) in left-sided colon cancer, 127.2 ng/mL (24.3-165.1 ng/mL) in right-sided colon cancer, and 129.5 ng/mL (25.4-181 ng/mL) in rectal cancer; B: Fecal calprotectin (FC). FC levels were 1324 μg/g (21.2-326.9 μg/g) in left-sided colon cancer, 807.1 μg/g (21.2-1002.7 μg/g) in right-sided colon cancer, and 238.6 μg/g (76.4-1217 μg/g) in rectal cancer. FC: Fecal calprotectin; hs-qFIT: High-sensitivity quantitative fecal immunochemical test.
