ABW

Adjusted Body Weight

For education. Check every result.

Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.

Fill in every field above, then select Calculate.

How it is calculated

ABW = IBW + 0.4 × (Actual - IBW). Used for drug dosing in obese patients.

About

A dosing weight between actual and ideal, used for drugs that distribute partly into fat tissue in obesity.
