2 July 2020 (Thursday) - D Dimer Reference Range
Normal ranges…. I’m showing my age. We haven’t had “normal ranges” in the lab for years – we have “reference ranges”. Bearing in mind the current importance of the D-dimer assay in the ongoing COVID-19 situation it is essential that we have the correct reference range for that analyte. Less than two hundred and foty-whatever isn’t actually much good in the elderly population who naturally have a raised D-dimer.
Ten times the patient’s age would seem to be a good estimate of the topend of “reference”
