In our cohort, 10 of 13 patients with nephelometric [kappa]-sFLC concentrations >1 g/L were expected to be quantifiable by SPE because the FLCs formed monoclonal bands that migrated in the [gamma] region.
This clinical case study reminds us that one of the original drawbacks of nephelometric determinations--antigen excess--may be important when measuring serum free light chain.
In conclusion, we have illustrated that antigen excess can cause falsely low serum FLC results with nephelometric techniques.
To compare the reliability of routine coagulation test (PT and APTT) using mechanical, photo-optical, and nephelometric methods by three automated coagulation analyzers.
The assays are based on affinity purified polyclonal antibodies that are coated onto latex particles which are used to produce kits specific for [kappa] FLCs and [lambda] FLCs for nephelometric and turbidimetric platforms.
Turbidity does not have a health-based guideline, but to ensure effectiveness of disinfection it should be no more than 1 nephelometric turbidity unit (NTU) and preferably much lower (WHO, 2011).
The supplier also reports that the filter takes wines with a turbidity of 25 to 1,000 NTU (nephelometric turbidity units) down to 0.00 NTU.
Turbidities of all samples show that they are between 0.113 and 2.63 NTU (Nephelometric Turbidity Unit).
Serum albumin levels were measured by the nephelometric method, and serum IMA levels were assayed with a [cobalt.sup.2+]-binding reduction (the interassay and intraassay coefficients of variation for the IMA, 8% and 5%, respectively).

The laboratory methods which are mainly used to determine the level of cysC are PENIA (particle enhanced nephelometric immunoassay) and PETIA (particle enhanced turbidimetric immunoassay), whereby PENIA is more sensitive and is considered the method of choice [5].
The quantifications of serum IgG, IgG1, IgG2, IgG3, IgG4 and salivary IgA was performed through nephelometric procedure.
