Anion Gap in Hypoalbumin States

 

Input
 

Na		mEq/L
Cl		mEq/L
HCO3		mEq/L
Normal Alb		gm/L gm/dL mcg/dL mg% mg/dL mg/mL ng/mL
Observed Alb		gm/L gm/dL mcg/dL mg% mg/dL mg/mL ng/mL

 

Results
 

Anion Gap		mEq/L
Adjusted Gap		mEq/L
Decimal Precision   0 1 2 3

 

Notes

• In this calculator, mcg is the abbreviation for micrograms.

 
Equations used
 

AnionGap = Na - Cl - HCO3

AdjustedGap = AnionGap + 2.5 * (NormalAlb - ObservedAlb)
