title: Discrepant results of amphotericin B assays on fresh versus frozen serum samples.
abstract: Amphotericin B assays on frozen serum samples (-20 degrees C) generally underestimate the serum levels obtained on promptly processed samples. The degree of the discrepancy is variable and independent of the length of time stored.
