Flashcards in Leukocytosis and Leukopenia Deck (19)
What should you use - the percentage or absolute count of the cell types on a CBC diff?
only care about the absolute
What's the one line where the percentage is helpful?
% of banded neutrophils
What blood lab changes do you see with a systemic bacterial infection?
marked toxic change
frequent left shift
evidence of DIC
What are some causes of neutrophilia?
acute blood loss
What are some examples of drug-induced neutrophilia?
What lifestyle activity can cause neutrophilia?
Neutropenia is usually caused by what two things?
Bugs or drugs
True or false: normal range for neutrophils varies depending on age and ethnicity.
kids have a lower normal range, as do african americans
What are the most common causes of monocytosis?
Infecions - esp chronic
(Viral, bacterial, esp things with granulomas)
What are the three main causes of monocytopenia?
What are the most common cause of eosinophilia?
What are some causes of basophilia?
Mast cell disease
(and basically any time there is an eosinophilia)
What are the infections that can cause mononucleosis syndromes?
Bordatella pertussis (classic appearance)
Mononucleosis is often characterized by a mild absolute ___ocytosis
lymphocytosis (over 4, but less than 20)
If lymphocyte count is over 20, what do you need to think about?
infections will never get that high.
Lymphocytopenia usually implies reduction in what T cell opulation?
Why don't we get as excited about lymphocytopenia as neutropenia?
people can manage to walk around with low lymphocytes without too much problem with infection until something goes awry
it's less of an emergency
What are some causes of lymphocytopenia?
viral infections (esp HIV, HHV8)
autoimmune disorders (SLE)
