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 the red bone marrow in the bones to create RBCs, is made in the kidneys).
Decreased HBG may be suggestive of:
Anemia due to nutritional deficiencies, blood loss, destruction of blood cells internally, or failure to produce blood in the bone marrow.
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, entrapment of platelets in an enlarged spleen, bone marrow failure from diseases such as leukemia.
RBC function is to:
Transport oxygen bound to HBG. Also transports small amounts of carbon dioxide
They are active phagocytes. They increase rapidly in number during short-term or acute infection. "First responders" to infection.
Increase during allergies, kill parasitic worms.
Responds to inflammation. Granules contain histamine (vasodilator), which is discharged at sites of inflammation.
The "Phils": neutrophils, eosinophils, basophils
Lymphocytes and monocytes
Important in the "immune response." B lymphocytes produce antibodies. T lymphocytes fight infections and tumors and also active B lymphocytes.
Phagocytes that become macrophages in the tissues. They are the "clean-up team." They increase in number during chronic infections, such at TB.
Monocyte increase may indicate:
Neutrophil increase may indicate:
New-onset (acute) infection.
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 stem cells). Lymphoid stem cells become lymphocytes. Myeloid stem cells become...
Includes the kidney (releases erythropoietin), which stimulates red bone marrow in the bones to produce RBCs. May be stimulated w/decreased RBC count, decreased O2 in blood, or...
Normal and therapeutic PT / INR values:
Normal INR should be appx. 1.0. Therapeutic level (prevent DVT) is between 2-3. This test is done during warfarin (Coumadin) therapy. Normal PT...
Normal PTT values:
Normal is between 30-45 seconds. This test is generally done while on heparin therapy (Lovenox).
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 test (PT--2 letters). You end up with 10 letters. Count the letters...
PT / INR test is used during: PTT test is used during:
PT/INR: Warfarin (Coumadin) therapy PTT: Heparin (Lovenox) therapy
