Cautions
Serum and ascitic fluid for determination of serum-albumin ascites gradient should be collected on the same day.
In very rare cases of gammopathy, in particular type IgM (Waldenstrom macroglobulinemia), (may cause unreliable results.
Colorimetric methods used for the determination of albumin may lead to falsely elevated test results in patients suffering from renal failure or insufficiency due to interference with other proteins. Immunoturbidimetric methods are less affected.
