Part Description
LP66405-9 Megakaryocytic nuclei
After megakaryocytes discharge the cytoplasm to form platelets, megakaryocyte nuclei or nuclear fragments may enter the peripheral blood stream, particularly in conditions associated with marrow myelofibrosis. The nucleus is single-lobed or multi-lobed. Chromatin is smudged and surrounded by a very scant amount of basophilic cytoplasm or no cytoplasm at all.

- Change Reason
- Microscopy is a better way to describe this test than manual count; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
