Albumin Dose Calculator

Work out albumin dose instantly with clear inputs, formula shown and shareable results.

About Albumin Dose Calculator

Converts a gram per kilogram albumin prescription into a volume for the chosen concentration, since 20% albumin contains 20 g per 100 mL.

Formula

Albumin volume

Dose (g) = weight x g/kg; volume (mL) = dose / concentration (g per 100 mL) x 100

Worked example

With the default values below, Albumin Dose Calculator returns Albumin dose of 70.0. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

When is 8 g per litre used?

After large-volume paracentesis, 6 to 8 g of albumin per litre of ascites removed is the standard replacement.

Is albumin better than saline?

For general resuscitation no, but it has specific roles in cirrhosis, spontaneous bacterial peritonitis and hepatorenal syndrome.
