Factitious Biochemical Reports which are Caused Due to Paraproteinaemia in Multiple Myeloma - A Case Report.

Factitious biochemical reports result in the misguiding of clinicians, unnecessary retesting, wrong diagnoses and incorrect treatments. A vigilant biochemist identifies these factitious biochemical reports and alerts the clinician regarding the proper interpretation of the biochemical reports, thus preventing a misdiagnosis and an incorrect treatment. We are presenting a case report of a multiple myeloma patient who presented with factitious biochemical reports which were caused due to paraproteinaemia. In the present case, the patient presented with an underestimation of urea and creatinine, an underestimation of sodium, low albumin levels and high phosphate levels. On repeating the same tests after dilutions and deproteinizing, the effects of the paraproteins on the above mentioned tests were reduced. Thus, from the observations of our study, we suggest that the interference by paraproteinaemia can be reduced by analyzing the biochemical parameters after dilution and deproteinization.
