Total protein and albumin concentrations did not differ significantly between Non-CF and CF subjects; total protein concentrations were 236.9 ± 51.3 versus 364.2 ± 70.8 μg/mL (p = 0.177) and albumin concentrations were 52.1 ± 26.0 versus 35.0 ± 10.1 μg/mL (p = 0.669), Non-CF versus CF, respectively. This evidence concerns the gene ALB and cystic fibrosis.
