Manufacturer Narrative

Electrophoresis testing was performed on one of the samples.The results show a high concentration of gamma-globulins which indicates a possible gammopathy.It was found that the sample on (b)(6) 2022 did not produce results due to a clogged needle indicated by an alarm flag.The investigation found that proteinemia, most likely caused by the high concentration of gamma-globulins, is the cause of elevated viscosity of the samples, which caused sample needle blockage.
