This may be attributable to the methods of performing the investigation, latex agglutination in the previous study and nephelometry
in the index study.
Microalbuminuria cannot be detected by simple urine dipstick testing, and the presence of abnormal albumin excretion should be performed using more sensitive methods such as nephelometry
. Adding the prevalence of macroalbuminuria found in our previous study to the current prevalence of MA, we can conclude that the overall prevalence of abnormal albumin excretion among SCD patients in this geographic area approximates 30%.
Serum and salivary IgA was analyzed using nephelometry
(Agappe Diagnostics, Kerala, India).
New assay of apolipoproteins A-I and B by rate nephelometry
Serum ceruloplasmin can be measured enzymatically, by antibody-dependent assays, by radial immunodiffusion, and by nephelometry
. The results are generally similar, except for the antibody-dependent and the immunodiffusion assays, which may overestimate the ceruloplasmin levels.
Serum Cystatin-C levels were measured by Nephelometry
method using a Fully Automated Autoanalyser (Accent 2000) with intra- and interassay % CV less than 5% and according to the procedure recommended by reagent manufacturer.
Rheumatoid factor (RF) and C-reactive protein (CRP) were quantified in serum using nephelometry
, and erythrocyte sedimentation rate (ESR) was determined utilizing the Wintrobe method.
Stivrins et al., "Reference intervals for serum IgG, IgA, IgM, C3, and C4 as determined by rate nephelometry
," Clin Chem, vol.
Elevated erythrocyte sedimentation rate (ESR) (39 mm/h) and C-reactive protein (CRP) level (6.8 mg/dL) (nephelometry
; normal < 0.5 mg/dL) were present.
Cp levels were measured with nephelometry
(Beckman-Array 360 Nephelometry
) using commercial reagents.
All samples were analyzed on Sysmex CS2000i (Sysmex Corporation, Japan), photo-optical clot detection; ACL Top (Instrumentation Laboratory Company, USA), nephelometry
method; and STA Compact Max (Stago, USA), viscosity-based (mechanical) clot detection.
Antimicrobial properties of cyclodextrin-antiseptics-complexes determined by microplate laser nephelometry
and ATP bioluminescence assay.
