The FLC results in Table 3 indicate that the guidelines for serum FLC need to be more stringent and more closely resemble the UPEP guidelines rather than the SPEP guidelines.
4] Nonstandard abbreviations: SPEP, serum protein electrophoresis; UPEP, urine protein electrophoresis; MM, multiple myeloma; MGUS, monoclonal gammopathy of undetermined significance; SMM, smoldering MM; IMWG, International Myeloma Working Group; FLC, free light chain; iFLC, involved (monoclonal) FLC; rFLC, ratio of [kappa] to [lambda] FLC; uFLC, uninvolved FLC.
The first autgregressive coefficient is negative and, except for UPEP and current capacity in column (3), significant.
In the first regime, the autoregressive coefficient is negative and, again except for UPEP and current capacity in column (7), significant.
The final estimates of the smoothness parameter, [gamma], are in the mid-twenties for UPM with both capacity variables and for UPEP with lagged capacity (columns ,  and ).
In accordance with other reports, a monoclonal peak with a [beta] mobility was present after both SPEP and UPEP.
To investigate which protein was mainly responsible for the monoclonal peak observed after UPEP (4), we performed co-immunofixation of both serum and urine proteins (Fig.
What investigations should be performed to characterize the protein responsible for the spike in the region of the UPEP results?
Early posttransplantation serum protein electrophoresis and serum immunofixation electrophoresis studies (at approximately 2 months) and UPEP studies (at 6 weeks) showed a small (3.
As a gauge of patients' response to therapy, serial UPEP studies combined with densitometric scanning are commonly used to measure changes in Bence Jones protein excretion over time.
Preanalytical costs for UPEP and urine IFE were then estimated as a proportion of all sample reception staff costs.
Staff costs (biomedical scientist grade 1) for sample analysis for UPEP and urine IFE.
