Unable to find CAP standard for this, however, assuming faster is better, managed to locate a study of automated analytic technologies for blood work, and the total times, including handling, were around 30 minutes. Pathological findings took somewhat longer. The report on these technologies can be found here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1860603/

Please forgive me if this is not perfectly germane to what you were seeking, though I thought the report, with references, might be of some utility.
