CXCL10 and cystic fibrosis: For example, of the samples tested by both platforms, the range of IP-10 in patients with CF (1289−5729 or 434–1989 pg/mL, quartiles) was distinct from that in the healthy subjects (0−1236 or 0–198 pg/mL, quartiles), which suggests IP-10 may serve as an effective biomarker for CF monitoring.
