The HNA-3 antigen system has two antigens (3a and 3b) which are located on the seventh exon of the CLT2 gene . The HNA-4 and HNA-5 antigen systems each have two known antigens (a and b) and are located in the β2 integrin. HNA-4 is located on the αM chain and HNA-5 is located on the αL integrin unit . [69]
Modern complete blood count analyzers can provide an automated white blood cell differential, but they have a limited ability to differentiate immature and abnormal cells, so manual examination of the blood smear is frequently indicated. [5] [6] Blood smear examination is the preferred diagnostic method for certain parasitic infections, such as ...
Plasma cells, also called plasma B cells or effector B cells, are white blood cells that originate in the lymphoid organs as B cells [1] [2] and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens.
One can see red blood cells, several knobby white blood cells including lymphocytes, a monocyte, a neutrophil, and many small disc-shaped platelets. A monocyte count is part of a complete blood count and is expressed either as a percentage of monocytes among all white blood cells or as absolute numbers. Both may be useful, but these cells ...

The Diego antigen (or blood group) system is composed of 21 blood factors or antigens carried on the Band 3 glycoprotein, also known as Anion Exchanger 1 (AE1). The antigens are inherited through various alleles of the gene SLC4A1 ( Solute carrier family 4), located on human chromosome 17 .
These antigens are almost universally present on human red cells, but their absence has been noted in some individuals and some have been associated with transfusion reactions or other problems. Finding compatible units for transfusion to a patient that lacks one of these antigens is a major challenge and some countries maintain rare donor ...
