The IFCC recommendation on estimation of reference intervals. The RefVal Program
Abstract
The International Federation of Clinical Chemistry (IFCC) published between 1987--91 a series of six recommendations on reference values in laboratory medicine. This paper reviews the history and scope of the fifth part of these recommendations. This fifth recommendation deals with statistical methods used for analysis of reference values and estimation of reference intervals. The RefVal program, which implements the recommended method, is also described.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
