Detecting Ion Levels, Changes to Monitor Health.

Ions can say a lot about a baby's health. High levels of chloride in sweat can indicate cystic fibrosis (CF), a disorder that causes respiratory and digestive problems; abnormal sodium levels are signs of increased risk for seizure or muscle problems; and too-high or too-low potassium concentrations can cause heart arrhythmias or other muscle issues. These ions-commonly called electrolytes- are also important throughout life. For instance, too much or too little sodium can lead to confusion, seizures, and muscle weakness or cramping.
