|
Neutrophils
|
31-57% of total white count.
First line of defense against infection; two types - Segs and Bands |
|
|
Segmented Neutrophils
|
31-57% of total white count.
Generally associated with a bacterial infection. |
|
|
Bands
|
0 % of total white count.
Immature neutrophils; highly suggestive of a bacterial infection |
|
|
What is meant by "left shift"?
|
Increase in Bands
Indicates a bacterial infection |
|
|
Monocytes
|
Normal 4-7% of total white count.
Second line of defense against infection. Indicates a viral infection. |
|
|
Lymphocytes
|
35-61% of total white count.
Indicates viral infection. |
|
|
B lymphocytes (B cells)
|
Humoral immunity
|
|
|
T Lymphocytes (T cells)
|
Cell-mediated immunity
|
|
|
Eosinophils
|
2-4% of total white cell count.
Indicates allergic disorders and parasitic infections. |
|
|
Basophils
|
0-1% of total white cell count.
Indicates systemic allergic reactions. |
|
|
RBC Indices
|
Measures the size and hemaglobin content of red blood cells.
Used to differentitate between different types of anemia |
|
|
RBC Indicies
Mean Corpuscular Volume (MCV) |
Indicates the avearge size of the RBC.
Normocytic: 75-94 Macrocytic:>94 Microcytic: <75 |
|
|
Macrocytic Anemia
|
MCV >94.
Occurs in folate or vitamin B12 deficiency, aplastic anemia, immune hemolytic anemia. |
|
|
Microcytic Anemia
|
MCV < 75.
Occurs in iron deficiency anemia; lead poisoning, thalassemia |
|
|
RBC Indicies
Mean Corpuscular Hemoglobin (MCH) |
Measures the average weigh of hemaglobin per Red cell (24-33pg(picograms)).
|
|
|
RBC Indicies
Mean Corpuscular Hemoglobin (MCH). Part 2 |
Increased MCH:Occurs in folate or vitamin B12 deficiency, aplastic anemia, immune hemolytic anemia.
Decreased MCH:Occurs in iron deficiency anemia; lead poisoning, thalassemia |
|
|
RBC Indicies
Mean Corpuscular Hemoglobin Concentration (MCHC) |
Indicates the average concentration of hemoglobin per red cell.
|
|
|
Mean Corpuscular Hemoglobin Concentration (MCHC) Part 2
|
Normochromic: 33-36%
Hyperchromic: >36% Hypochromic: <33% |
|
|
MCHC
Hyperchromic |
> 36%
Associated with hereditary spherocytosis |
|
|
MCHC
Hypochromic |
<33%
Associated with iron deficiency; thalassemia. |
|
|
Reticulocyte Count
|
Immature red blood cells.
Normal range 0.5-1.5% |
|
|
Absolute Neutrophil Count (ANC)
|
Represents the actual number rather than the % of neutrophils.
Range >1000. |
|
|
Neutropenia
|
Absolute neutrophil count <1000.
|
|
|
Absoulte Neutrophil Count Calculation
|
{(Bands + Segs) X WBC}/100 = ANC
|
|
|
Anion Gap
|
Represents anions other than bicarbonate and chloride required to balance the positve charge of NA+
Normal AG = 12mEq/L +/_ 2 mEq/L. Useful in determining the degree of metabolic acidosis |
|
|
Anion Gap Calculation
|
Aniorn Gap = NA+ - (Cl- + CO2)
NA = Sodium level Cl = Chloride level CO2 = Bicarb level |
