Hypochromia (HYPO)
Definition
The Hypochromia flag is triggered if the percentage of cells with low cellular
hemoglobin concentration (%HYPO) is equal to or greater than 4.0%.
The %HYPO parameter indicates the percent of cells that have a cellular
hemoglobin concentration less than 28 g/dL and is derived from the RBC HC
histogram.
Default trigger values for the three severity levels are:
+
++
+++
The %HYPO value is intended for flagging and laboratory purposes only.
