eosinophils
neutrophils basophils |
|
Agranular leukocytes?
|
monocytes
lymphocytes |
|
Where is the site where bone marrow samples in an adult is collected?
|
sternum or the iliac crest because this is where blood cells are still being produced.
|
|
What carries about 95% oxygen to the body and 27% carbon dioxide away from the body?
|
hemoglobin
|
|
hemoglobin
|
helps maintain proper pH balance of blood as it picks up and drops off oxygen and carbon dioxide.
|
|
Hormone erythopoietin - produced in kidney
|
RBC's produces erythopoietin when body cells sense a low oxygen level.
|
|
Anemia
|
Most frequent hemoglobin disease seen in ambulatory care setting: IRON DEFICIENCY ANEMIA IS THE MOST COMMON TYPE
|
|
Anemia types
|
nutritional anemia (insufficient in diet)
hemorrhagic anemia (losing iron because of excessive bleeding) aplastic anemia (bone marrow diseases) |
|
What are the symptoms of anemia?
|
fatigue, lack of oxygen
|
|
RBC's are hypochromic (pale)
|
low hemoglobin because lack of oxygen
|
|
Hgb
|
Hemoglobin gives different information than hematocrit from RBC's
|
|
Hct
|
Hematocrit, gives different information than hemoglobin from RBC's
|
|
TMPS: total practice management system?
|
Where quality controls & test results are recorded in TMPS
|
|
CBC
|
Complete blood count
|
|
What does CBC hemoglobin carry?
|
O2 and Co2
|
|
Erythropoietin?
|
homes signal production of RBC/hemoglobin

packed cell showing separation, capillary tube, plasma, buffy coat (WBC's & platelets), RBC's and sealing clay
|
|
What is cytoplasm full of?
|
Granules-granulocyates = neutrophils, basophils and eosinphils (they all end with "phil,"
|
|
Lymphocytes
|
it travels through the lymphatic system
|
|
WBC's-leukocytes are divided into to types, what are they?
|
Granular and agranular.
|
|
Agranulocytes are
|
lymphocytes and monocytes
|
|
Of the three leukocytes which has the most?
|
Neutrophils-they destroy bacteria
|
|
Basophils
|
They release histamines to increase inflamation
|
|
Eosinphils
|
They release neutralize histamines.
|
|
Monocytes
|
"Eat" cellular debris and other substances.
|
|
Normocytic
|
When erythrocytes are normal
|
|
Macrocyte
|
When erythrocytes are larger
|
|
Microcyte
|
When erythrocytes are smaller
|
|
How many molecules of hemoglobin are in each RBC?
|
Each red blood cell can contain between 240 and 300 million molecules of hemoglobin.
|
|
Normochromic?
|
Normal-proper amount of hemoglobin in RBC's
|
|
Hypochromic?
|
Not enough hemoglobin, have too large of a pale central area.
|
|
MCV
|
Mean corpuscular volume
|
|
MCH
|
Mean corpuscular hemoglobin
|
|
MCHC
|
Mean corpuscular hemoglobin concentration
|
|
Hematocrit tube
|
separation of cellular components
|
|
ESR-Erthrocyte sedimentation rates, also commonly known as Sed Rate?
|
A blood test that detects and monitors inflammation in the body. It measures the rate at which red blood cells (RBCs) in a test tube separate from blood serum over time, becoming sediment in the bottom of the test tube. The sedimentation rate increases with more inflammation.
|
|
What is the normal sedimentation rate?
|
The normal sedimentation rate (Westergren method) for males is 0-15 millimeters per hour, females is 0-20 millimeters per hour. The sedimentation rate can be slightly more elevated in the elderly. TEST MUST BE READ AT EXACTLY 60 MINS.
|
|
What is C-reactive protein (CRP)?
|
It is a protein produced by the liver and found in the blood.
It is helpful in determining systemic inflammatory conditions, i.e. autoimmune diseases, inflammatory bowel conditions & some forms of arthritis. It is made by the liver and released into bloodstream. It is increased when there is infection and inflammation present. |
|
What is Protime (PT)?
|
It is the method of monitoring coagulation time.
