Use of haemolysis index to estimate potassium concentration in in-vitro haemolysed serum samples

Abstract

The magnitude of the relationship using authentic patient data with the Beckman LX20PRO haemolysis index is in keeping with previously described relationships. Use of the haemolysis index on the Beckman LX20PRO to predict potassium concentration in haemolysed samples is not sufficiently accurate to obviate the need for repeat analysis, but can be used to prioritise the need for urgent repeat analysis.
