reactive lymphs, Downey cells, virocytes

represent nonfunctional cells seen in viruses (mono)

Question 4

Answer 4

normal WBC count with an increased percentage of lymphocytes due to viral infections such as rubella, varicells, mumps

Question 5

absolute lymphocytes

Answer 5

elevated WBCs with an increase in lymphocyte count due to viruses

Question 6

atypical lymphocyte

monospot test

Question 11

4.8 white count
30 neutrophils
50 lymphs
2 monocytes and eosinophils
16 atypical lymphocytes
diagnosis?

Answer 11

white count is low
neutrophils= neutropenia
lymphs= lymphocytosis
monocytes and eosinophils= normal
atypical lymphocytes seen with viral infections (mono)
late mono, viral pneumonia, viral hepatitis (depends on s/s)

Question 17

CD4 count

Answer 17

how well the immune system is functioning
