According to recent research from the United States, "there is a growing interest in the use of granulocytic surface markers for the diagnosis of some inherited and acquired disorders, such as Shwachman-Diamond syndrome and myelodysplastic syndromes. Understanding the impact of physiologic factors, such as age, gender, pregnancy, race, and stress on granulocytic surface markers is essential for appropriate interpretation of results. Some surface markers show marked variations at the very early and the very late stages in life."
"Fetal granulocytes tend to have a lower expression of CD11b, CD11c, CD18, and CD32. Term neonatal granulocytes are frequently associated with a lower expression of CD10, CD11b, CD13, CD33, and CD62L and a higher expression of CD55 and CD64. Elderly individuals have shown a higher expression of CD64," according to M.T. Elghetany and colleagues, University of Texas Medical Branch.
"Pregnancy is associated with temporary changes in granulocytic surface markers, such as a lower expression of CD16 and a higher CD64, ...
