Fibrinogen was measured by the thrombin time method, PT by Quick's method, and fibrin and fibrinogen degradation products by the latex agglutination method.
With the help of a new coupling agent Si747, silica water slurry and styrene butadiene rubber (SBR) latex were successfully co-coagulated by the latex compounding method, even silica/SBR masterbatches with silica loading as high as 200 phr could be prepared by such method.
HbA1c was measured by the latex agglutination method.
Capsular serotyping was performed by the latex agglutination method using antisera specific for each capsular type (Ia, Ib, II-VII) using Strep-B-Latex kits (Statens Serum Institute, SSI, Sweden).
The serum concentration of fibrin degradation products (D-dimer) was measured by the latex agglutination method (D-DI Liatest, Diagnostica Stago, Asnières, France) with a limit of detection of 0.22 μg/mL.
The C-reactive protein concentration was appreciated by the latex-agglutination method.
RF was measured by using a latex method, and a titer of > 1 40 was classed as positive.
Serum high-sensitive CRP was determined by the latex particle-enhanced immunoturbidimetric method with the CRPex-HS CRP test (Good Biotech Corp., Taichung, Taiwan), with protein multicalibrator (ProDia International, Sharjah, UAE).
Hemoglobin A1c was measured by the NGSP National Glycohemoglobin Standardization Program -approvedd technique using the latex cohesion method with a commercial kit (Determiner HbA1c, Kyowa Medex, Tokyo, Japan).
