You need to perform analyses on 100 blood samples to determine insulin concentrations. Each radioimmunoassay (RIA) kit is able to analyze about 50 samples and so you will need at least two kits. After analyzing the 100 samples, you perform a reliability test and discover that your intra-assay coefficient of variation (CV) is 21% and 19% and the inter-assay CV is 7%. You conclude:

a. Your reliability with performing these assays STINKS

b. The inter-assay CV is close to the Gold Standard and therefore acceptable

c. a and b

d. None of the above
