ARCHETYPE Examination of a cleavage-stage embryo (openEHR-EHR-CLUSTER.exam_embryo.v1)

ARCHETYPE IDopenEHR-EHR-CLUSTER.exam_embryo.v1
ConceptExamination of a cleavage-stage embryo
DescriptionMorphological findings obtained by microscopy of the human cleavage-stage embryo.
UseUse to record morphological observations appropriate for the cleavage-stage of human embryo development, usually as part of assisted reproduction treatment. This archetype has been specifically designed to be used in the 'Observations detail' SLOT within the 'OBSERVATION.embryo_assessment' or 'ACTION.procedure' archetype, but can also be used within other ENTRY or CLUSTER archetypes, where clinically appropriate.
MisuseNot to be used for recording observations on oocytes, zygotes and blastocysts - use specific CLUSTER archetypes for this purpose.
PurposeTo record structured observations about a human cleavage-stage embryo.
