Dear All, Pathologists and laboratory message standards developers have over many years made clear to me that it is always good practice to include the applicable normal range with individual instances of observed values, since those ranges are not fixed across measurement methods, devices, organisations or over time. Published reference ranges in clinical textbooks etc. are only a guide for those tests in which the variation is nowadays quite small.
For this reason, right from Synapses days - a decade ago! - , we have not sought to put reference ranges into the archetype specification, but (as Tom has stated) only to ensure that the archetype caters for the inclusion of reference range instances along with the observed value(s). With best wishes, Dipak ________________________________________________________ Dr Dipak Kalra Clinical Senior Lecturer in Health Informatics CHIME, University College London Holborn Union Building, Highgate Hill, London N19 5LW Direct Line: +44-20-7288-3362 Fax: +44-20-7288-3322 Web site: http://www.chime.ucl.ac.uk -------------- next part -------------- An HTML attachment was scrubbed...
