Fecal CD14 levels in subjects with diarrhea associated with CD14 -1491 C > T single nucleotide polymorphisms in the CD14 gene. Data are presented in pg/mL for CC (n = 26), CT (n = 11), and TT (n = 4) genotype groups. Fecal sCD14 in the stool specimens determined for patients in the -4191 CC genotype group ranged from 947 to 400,360 pg/mL (mean level ± standard deviation [SD], 40,697 ± 94,486); for visitors in the CT genotype group, it ranged from 2118 to 31,079 pg/mL (mean value ± SD, 11,162 ± 10,271); and for visitors in the TT genotype group, it ranged from 4383 to 7361 pg/mL (mean value ± SD, 5872 ± 1489).
