Part Description

LP15392-1   Anion gap 4
Anion Gap 4 is the difference between the sum of serum sodium + serum potasium and the sum of the serum bicarbonate+ chloride. Calculated based on the concentration of four electrolytes as follows: ([Na+] + [K+]) − ([Cl−] + [HCO3−]). An increased gap indicates the presence of an unmeasured anion.
