Abstract: A method for determining an amount of functional albumin includes providing a test sample containing a defined amount of albumin of unknown binding capacity and a reference sample containing the same defined amount of albumin having a reference binding capacity, incubating the test and reference samples with a defined amount of at least one albumin-binding marker M under conditions that allow formation of complexes of the at least one albumin-binding marker M and albumin (M:A), removing the complexes, detecting a presence or an amount of unbound marker M in the samples after removal of the complex (M:A) through a first and a second test strips that allow for a determination of an amount of unbound marker M, and determining the amount of functional albumin based on the presence or the amount detected of marker M.

Abstract: Determining the relative binding capacity of albumin (A), and amount of functional albumin, involves at least two measurement solutions of a test and reference sample. The measurement solutions contain an albumin-binding marker M. The marker in the measurement solution of the test and reference samples exceeds the presumed available albumin binding capacity. The test sample contains a defined amount of albumin of unknown binding capacity. The reference sample contains the same defined amount of albumin having a reference binding capacity. The measurement solutions are incubated under conditions that allow M:A complexes to form. The M:A complexes are removed. The presence or amount of unbound marker M in the solutions is detected after M:A complex removal by a test strip that allows determination of the unbound marker. The relative binding capacity of albumin in the test sample based on the presence or detected amounts of unbound marker is determined.
