ISO/TC 212 WG1 started the activity “13.3 Harmonization of terminology across ISO TC212”
CLSI changed all titles related to collection from “primary samples” to “specimen”.
ISO/DIS 15189 has 6.3.5 “Specimen collection facilities”
ISO 6717:2021 has: “3.17 specimen… [SOURCE: ISO 15189:2012, 3.16, modified – the preferred term 'primary sample' has been deleted.]”
ISO 20916:2019 3.47 specimen … [SOURCE:ISO 18113-1:2009, 3.54, modified — “Specimen” is the first preferred terms,
The International Medical Device Regulators Forum (IMDRF) uses the
term specimen.
WHO uses the term “specimen”.
CLSI in many documents uses the term “specimen”.
ILAC uses the term “specimen” in G18 and G26.
CDC uses the term “specimen”.
ISO itself in several documents uses the term specimen even in the
title.
Therefore, "specimen” is the standard term in collection activities.
“primary sample” is little more than a form of "slang"and
can cause confusion with other terms.
“sample” retains its value for statistical and
measurement activities.
