- The colors indicate the changes in the cystic fibrosis diagnosis classification, according to the chloride dose. The table also shows the obtained sweat weight value, which is associated with the chloride dilution in the amount of sweat collected and may change the sweat test result. The sweat test is defined in mmol/L. The sweat weight is defined in mg. Using different currents, we achieved different results in the classification of the sweat test, mainly, considering the borderline value. Also, in the present study, we included only individuals with clinical suspicion of cystic fibrosis, but sometimes, without a close diagnosis (absence of two CFTR mutations and/or two sweat tests ≥ 60 mmol/L). In this context, we found a lot of variability that could be a reflex of the patient enrolled in the studied sample. Finally, all the currents used to induce sweating showed a close capacity to induce the sweat weight above 75 mg
