Question 9 Complete Market ost of o hax question Consider the attached flow cytometric data (see image) derived from the blood of an HIV patient some 5 years after diagnosis. Which one of the following represents the percentage of the total population of T cells in this patient's blood? 33% 29% CD3 PE -100 101 102 103 10° 19,4% 18.6% 10 10 CD4 10 10 Select one: a. 47.6% b. 62% 0.38% d. 18.6% .52.4%

Answer 1

33% + 29% = 62%.

Because this graph shows that cells in upper left quadrant are CD3+/CD4- and upper right quadrant cells are CD3+/CD4+. So total number of T cells will be a sum of both these quadrants.
