Question 2

Explain why determining the amount of fetal bleed into a mother is essential for preventing hemolytic disease of the newborn.

Accepted Answer

When fetal red blood cells enter materna

Question 3

A specimen has a total white blood count of 10,000 cells/uL of which 35% are lymphocytes. Flow cytometry analysis revealed that 50% of the lymphocytes are CD4+, so the absolute CD4 count is ________cells/uL.

The answer of A specimen has a total white blood...

Question 4

Why are whole blood, bone marrow, and bronchoalveolar lavage specimens typically good specimens for flow cytometry?

Accepted Answer

A) The sizes of cells in these specimens fall within the range that can be analyzed by laser light scatter. 
B) There is less debris in these specimens to non- specifically scatter light. 
C) The cell types in these specimens usually have more well- defined antigens. 
D) These are generally cell suspensions with cells occurring separately and singly in the mixture.
