However, a number of things can easily go wrong during this stage of the process and the labs that calculate radiocarbon dates are subject to constant scrutiny to ensure that they are up to par; but even so, samples sent to different labs often produce slightly various results. These are established by a variety of elements, including but not limited to: the quality of the sample, the quality of the lab, and the age of the sample.It is when a sample is measured that the real complications begin: as the process to assign a meaningful date to the scientific chronology is rather erudite. dates (raw dates that are calibrated to the same calendar system are written without capital letters as b.c./ a.d.
