1. Normal range for >18y adults was determined by testing 271 male and female healthy blood donors at UCSF.
2. Pediatric range same as adults as referenced in Soldin, "Pediatric Reference Intervals" 6th ed. 2007, Methods 1,2,3.
|Synonyms||Cl; Cl-; Electrolytes; Anion gap|
|Stability||Room temperature 8 hours, refrigerated 2 days, frozen at -20C 1 week|
|Turn around times||STAT 1 hour, Routine 4 hours|
|Additional information||Bromide gives falsely high results.
The anion gap is calculated from the serum Sodium, Chloride and Total CO2 values using the equation: Na-(CL+CO2). The calculation is automatic whenever all three of the electrolytes are ordered together. It is not a separately orderable test. Normal range for the Anion Gap is 4-14.
