Novel real-time quantitative PCR test for trisomy 21.

method correlated well with the other two compared hs-CRP methods in the range of 0.2–100 mg/L. At concentrations 100 mg/L, however, poor correlations were found between all compared methods. Because we are convinced that for the clinical laboratory it is most practical to use one CRP method for the complete measuring range, further investigation to improve agreement among the different methods in the higher range is required.
