Blood 5 Flashcards
inverted ratio
seen in viral infections, lymphocytic luekemia, lymphocytic leukemoid reactions, normal in children less than 9 years
lymphs >segs
lymphopenia is seen in?
AIDS
Hodgkin’s
bacterial infections
atypical lymphocytes
reactive lymphs, Downey cells, virocytes
represent nonfunctional cells seen in viruses (mono)
relative lymphocytosis
normal WBC count with an increased percentage of lymphocytes due to viral infections such as rubella, varicells, mumps
absolute lymphocytes
elevated WBCs with an increase in lymphocyte count due to viruses
atypical lymphocyte
T lymphocyte in a state of immune activation (mono)
mono is due to?
epstein barr virus
signs and symptoms of mono
vague onset, fever, sore throat, neck pain, fatigue, spelnomegaly, lymphadenopathy, headache
early in a mono infection, WBC count is
reduced
what is the test or mono?
monospot test
4.8 white count 30 neutrophils 50 lymphs 2 monocytes and eosinophils 16 atypical lymphocytes diagnosis?
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)
WBC 14
segs 35
lymphs 55
atyplymph 10
inverted ratio
14 looks like bacterial
with increase in lymphs and atypical lymphs, virus
how is HIV/AIDS spread?
contamination with secretions, blood, extrections and infected tissues
s/s of HIV/AIDS
marked decrease in T helper cells
cellular immunity depresion
opportunistic infection
hematology reveals ACD, lymphopenia, neutropenia, thrombocytopenia
when is someone diagnosed with AIDS?
when CD4 count drops below 200 due to advanced HIV disease
normal range of CD4 cells
between 600 and 1500
CD4 count
how well the immune system is functioning
viral load
low rapidly HIV is progressing
measures the amount of HIV in the blood (lower levels better than higher levels)
increased monocytes are from?
recovery from acute infections
monocytic leukemia
Hodgkin’s disease
TB
function of monocytes
scavenger
phagocytosis of dead or dying cells, bacteria, fungi or viruses
back up neutrophils (present in recovery phase of infections)
what substances do monocytes give off?
lysosomes
thromboplastin
platelet activating factor
etc.
after being in the blood, where do monocytes go?
tissues as different types of macrophages
eosinophils
ingestion of parasites and limits allergic reaction
often associated with hypersensitivity reactions
contain histamine
eosinophilia is seen in?
allergies
parasitic infections
Hodgkin’s lymphoma
basophils
involved with immediate hypersensitivty reaction by release of histamine an dheparin
increased basophils indicates
allergies chicken pox splenectomy polycythemia vera Hodgkin lymphoma
