We are currently running the Total PSA and free PSA on the Roche e801 module. One of our sister's lab was cited because we are running this assay for males all ages, when the IFU states the intended use of this assay is just for males >50 years old. Are you, Roche users, running this assay for male patients <40, and 40-50 as an LDT? Any thoughts?
Interesting issue today, we've found that new lots of Iron reagents on our Alinity instruments all running a pretty consistent 20% higher on both patients and controls. Abbott has told us this is affecting all their new lots and that there is no fix besides suggesting we apply a calibration factor but steadfastly insisting this is not an official recommendation. There are apparently no more of the old lot of reagents available and everything now is running high. Anyone else on Alinity seeing this? And if so, how are you dealing with it?
Is anyone aware of a CLIA lab in the US that will test for anti-insulin receptor antibodies? We have a patient with insulin autoimmune syndrome who is displaying severe insulin resistance, perhaps more in line with type B insulin resistance.
