Side ASide B
Normal hemoglobin (HBG) values:
13.5 - 16.5 male 12.0 - 15.0 female
Normal hematocrit (HCT) values are:
41 - 50 male  36 - 44 female
Normal RBC count is: 
4.5 - 5.5 male 4.0 - 4.9 (x 106 /ml) female
Normal platelet count is: 
100,000 to 450,000
Normal WBC count is: 
4,500 - 10,000
Normal segmented neurtophil count is:
54 - 62%
Normal band form count is: 
3 - 5%  (above 8% indicates left shift)
Normal basophil count is: 
Normal eosinophil count is: 
Normal lymphocyte count is:  24-44%
Normal monocyte count is: 
Increased WBC count may be suggestive of: 
Bacterial/viral infection, leukemia.
Reduced RBC values (anemia) may be suggestive of: 
Hemorrhage, bacterial infections, low B-12, kidney disease (erythropoietin, which signals...
Decreased HBG may be suggestive of: 
Anemia due to nutritional deficiencies, blood loss, destruction of blood cells internally,...
Decreased HCT may be suggestive of: 
Anemia due to nutritional deficiencies, blood loss.
Reduced platelet count may be suggestive of: 
Thrombocytopenia, acute blood loss, drug effects (such as heparin), infections w/sepsis,...
RBC function is to:
Transport oxygen bound to HBG.  Also transports small amounts of carbon dioxide
Neutrophil function:
They are active phagocytes.  They increase rapidly in number during short-term or acute...
Eosinophil function:
Increase during allergies, kill parasitic worms.
Basophil function:
Responds to inflammation.  Granules contain histamine (vasodilator), which is discharged...
Granulocytes include: 
The "Phils":  neutrophils, eosinophils, basophils
Agranulocytes include:
Lymphocytes and monocytes
Lymphocyte function:
Important in the "immune response."  B lymphocytes produce antibodies.  T lymphocytes...
Monocyte function: 
Phagocytes that become macrophages in the tissues.  They are the "clean-up team." ...
Monocyte increase may indicate:
Long-term infection
Neutrophil increase may indicate:
New-onset (acute) infection.
Platelet function:
Clot blood.  Are not "cells", but fragments of megakaryocytes.
Blood cell formation: 
Hemocytoblasts (stem cells) become secondary stem cells (either lymphoid stem cells or myeloid...
RBC formation: 
Includes the kidney (releases erythropoietin), which stimulates red bone marrow in the bones...
Normal and therapeutic PT / INR values:
Normal INR should be appx. 1.0.  Therapeutic level (prevent DVT) is between 2-3.  This...
Normal PTT values: 
Normal is between 30-45 seconds.  This test is generally done while on heparin therapy...
Trick to remembering which test goes with which drug:  PT / PTT
Count the letters in the word WARFARIN (8-letters), then add the letters from the corresponding...
PT / INR test is used during:      PTT test is used during: 
PT/INR:  Warfarin (Coumadin) therapy   PTT:  Heparin (Lovenox) therapy
