The customer called the technical solutions center (tsc) about the discordant epo result. The customer stated that the laboratory has run dilutions on other epo samples and other assays there are no problems. Based on this, the tsc specialist determined that the instrument did not require a field service engineer to inspect. The instructions for use (ifu) for the epo assay on the immulite 2000 instrument does indicate that the assay has limitations.
