calculate_saag: Serum-Ascites Albumin Gradient (SAAG)

Description

Calculates the Serum-Ascites Albumin Gradient (SAAG) to help determine the etiology of ascites. The gradient is the difference between the serum albumin concentration and the ascites fluid albumin concentration. It distinguishes between ascites caused by portal hypertension and other causes.

Usage

calculate_saag(serum_albumin, ascites_albumin)

Value

A list containing:

SAAG_Score

The calculated gradient (Serum - Ascites).

Interpretation

Diagnostic classification based on the 1.1 g/dL threshold.

Arguments

serum_albumin

Numeric. Serum Albumin level in g/dL.

ascites_albumin

Numeric. Ascites fluid Albumin level in g/dL.
