View source for Cellavision (Year 1)

Information for using Cellavision in Year 1. This will focus on WBC categorization/differentials and RBC morphology.

== WBC Classes ==
When classifying WBCs, they can be divided into the following basic categories:

* Segmented neutrophils
* Eosinophils
* Basophils
* Lymphocytes
* Monocytes
* Giant thrombocytes
* Smudge cells
* Artifacts

=== Neutrophils ===
All neutrophils are classified as segmented neutrophils regardless of whether they are band or segmented.

=== Giant thrombocytes ===
All platelets that are approximately the size of a red blood cell, or larger are classified as giant thrombocytes.

=== Smudge cells ===
Any cell without an intact cell membrane are considered smudge cells. This includes cells that look 'exploded,' or when it is difficult to tell whether it is a cell or not.

* Anything that looks like a lysed or broken cell
* Anything that appears like it might have been a cell
* Platelets (as long as they're not giant platelets, that is to say any platelets smaller than an RBC are considered smudge cells)

=== Artifacts ===
Includes any other item that is not included above. For example, this includes stain deposits or debris.

* Stain deposits
* Stain smears
* Debris

== RBC Morphology ==

==== Grading characteristics on Cellavision ====
Only grade the following categories:

* Polychromatic cells
* Hypochromatic cells
* Microcytes
* Macrocytes
* Target cells
* Schistocytes
* Helmet cells*
* Sickle cells
* Spherocytes
* Elliptocytes
* Ovalocytes
* Teardrop cells
* Stomatocytes
* Acanthocytes
* Echinocytes
* Howell-Jody Bodies
* Pappenheimer Bodies
* Basophilic Stippling
* Parasites
* Rouleaux
* RBC Agglutination
* Non-specific
* Giant Platelets
* Bite and Blister Cells
* Oval Macrocytes
* Normal

When the smear is normal or non-specific:

* Select ONLY that category (normal OR non-specific) and assign it a value of 3.
