Test Comments:

The drug Eltrombopag (Promacta) and its metabolites have been identified as causing a false positive bias in total protein measurement when tested on Ortho Vitros instrumentation which is utilized at Parkview Bryan and Parkview Montpelier laboratories. If your patient is on Eltrombopag and being directed to one of these locations for testing, please contact the lab at 260-266-1500 so that testing can be performed using an alternate instrument.
