Blood Flashcards
difference between plasma and serum
serum does not contain clotting factors while plasma does
erythrocytes
-red blood cells
- deliver O2
- remove CO2
leukocytes
-white blood cells
- help protect body against infection
thrombocytopenia
low platelet count
- affect body’s ability to clot blood
thrombocytes
-platelets
- maintain vessel wall integrity
- patch blood vessels
- control blood clotting
band neutrophils
immature leukocytes
what can band neutrophils indicate
severe or overwhelming infection
- should not be in circulation
neutrophilia
increased neutrophils
- secondary bacterial infection
- inflammation
neutropenia
decreased neutrophils
- acute overwhelming infection (possible GI)
- neoplasia
lymphocytosis
increased lymphocytes
- immune system and antibody function
- exercise
- disease
lymphopenia
decreased lymphocytes
- immune system and antibody function
- secondary bacterial infection
- acute overwhelming infection
Eosinophilia
- allergic stimulation
- irritating stimulation
1. allergic bronchitis
2. eosinophilic bowel
basophilia
- allergic/parasitic diseases
- allergic responses
Monocytosis
- chronic infections
- come in during chronic stages of illness
- “garbage hauler”
1. bacterial infection
2. chronic inflammation
causes of anemia
- internal bleeding (internal wound)
- external bleeding (wound)
- nonregenerative (bone marrow not responding)
- decreased red blood cells
fibrinogen
- indicator of inflammation
- indicator of bacterial infection
what is the normal range of fibrinogen
N<300
Serum Amyloid A
- major acute phase protein
- reaction to tissue injury
- healthy= low concentration
- inflammation= increases
pancytopenia
affecting all over
what does cortisol cause
lymphocyte count to go down (lymphopenia)
what are the main functions of neutrophils
first responders to chemotactic stimuli in body
- initially see neutropenia drop until marrow had time to kick out more neutrophils
segmented
old leukocytes
hematocrit
tells you about red blood cell % height and plasma
what are red blood cell indices
- hematocrit
- hemoglobin
- RBC count
how is anemia diagnosed
- decreased hematocrit and RBC
composition of blood
plasma- on top; mostly water
buffy coat- middle; cellular components; white blood cells
red blood cells- bottom
what is a complete blood count
count different cells from blood collection
auto platelet
counts thrombocytes
HGB
hemoglobin
HTC
hematocrit
CBC with differential
complete blood count and counting all different members of white blood cells
what is in the plasma component of blood
- albumin
- antibodies
- hormones
- clotting factors
- electrolytes
blood tubes
purple- plasma/EDTA and used for CBC
red top- serum
mottled top- serum
what organ is involved when erythrocytes fluctuate
kidney
