HEMOGLOBIN
RBC: COLOR AND SIZE
SALMON PINK, 7-8MM
RBC: ZONE OF PALLOR
1/3 OF CENTER
LOSS OF OXYGEN CARRYING CAPACITY
DECREASED RBC COUNT
DECREASED RBC HEMOGLOBIN CONCENTRATION
ANEMIA
INCREASED RBC COUNT CAUSING HYPERVISCOCITY
INCREASED RBC COUNT
INCREASED RBC MASS
POLYCTHEMIA
RELIES ON DRABKIN REAGENT
HEMOGLOBIN
WEAK SOLUTION OF POTASSIUM CYANIDE AND POTASSIUM FERRICYANIDE
USED FOR MEASUREMENT OF HEMOGLOBIN
DRABKIN REAGENT
RATIO OF THE VOLUME OF PACKED RBCS TO VOLUME OF WHOLE BLOOD
HEMATOCRIT
NORMAL RATIO OF HCT
50%
HCT IS ALSO CALLED
PACKED CELL VOLUME/ PCV
IT IS EXCLUDED FROM HCT DETERMINATION
BUFFY COAT
THIS IS USED TO EVALUATE AND CLASSIFY VARIOUS TYPES OF ANEMIAS ACCORDING TO RBC INDICES
HEMATOCRIT/PCV
THE PERCENTAGE OF RBC IN A VOLUME OF WHOLE BLOOD
HEMATOCRIT
USES RBC COUNT, HGB AND HCT
-MEAN CELL VOLUME/MCV
-MEAN CELL HEMOGLOBIN/MCH
-MEAN CELL HEMOGLOBIN CONCENTRATION/MCHC
RBC INDICES
RBC INDICES
- MCV
- MCH
3.MCHC
4.RDW
MCV IS RECORDED IN WHAT UNIT
FEMTOLITERS (fL)
RBC INDICES THAT REFLECTS THE RBC DIAMETER ON A WRIGHT STAINED BLOOD FILM
MCV
MCHC IS RECORDED IN WHAT UNIT
GRAMS PER DECILITER (g/dL)
RBC INDICES THAT REFLECTS THE RBC STAINING INTENSITY
MCHC
RBC INDICES THAT REFLECTS THE RBCs CENTRAL PALLOR
MCHC
MCH IS RECORDED IN WHAT UNIT
PICOGRAMS (pg)
RBC INDICES THAT EXPRESSES THE MASS OF HEMOGLOBIN PER CELL
MCH
RBC INDICES THAT PARALLELS THE MCHC
MCH
4TH RBC INDEX
RDW
RBC INDICES THAT EXPRESSES THE DEGREE OF VARIATION IN RBC VOLUME
RDW
EXTREME RBC VOLUME VARIABILITY IN DIAMETER
ANISOCYTOSIS
RDW IS BASED ON THE - OF RBC
STANDARD DEVIATION
0.5-2.5% OF RBCS THAT EXCEED THE 7-8 AVE DIAMETER
BLUE GRAY COLOR
POLYCHROMATIC ERYTHROCYTES/ RETICULOCYTES
THESE ARE NEWLY RELEASED FROM THE RBC PRODUCTION SITE
POLYCHROMATIC ERYTHROCYTES/ RETICULOCYTES
INDICATES THE ABILITY OF THE BONE MARROW TO INCREASE RBC PRODUCTION IN ANEMIA CAUSED BY BLOOD LOSS OR EXCESSIVE RBC DESTRUCTION
POLYCHROMATIC ERYTHROCYTES/ RETICULOCYTES
USUALLY FROM BM OR LYMPHOID TISSUE DEDICATED TO PROTECT HOST
NEARLY COLORLESS
LEUKOCYTES
DECREASED WBC COUNT
LEUKOPENIA
INCREASED WBC COUNT
LEUKOCYTOSIS
PHAGOCYTIC CELLS, SEGMENTED/MULTI-LOBED NUCLEI
NEUTROPHILS
INCREASE IN NEUTROPHILS= BACTERIAL INFECTION
NEUTROPHILIA
DECREASE IN NEUTROPHILS= MEDICATIONS/ VIRAL INFECTIONS
NEUTROPENIA
ROUND WITH BRIGHT ORANGE-RED CYTOPLASMIC GRANULES
EOSINOPHILS
ELEVATED EOSINOPHILS= ALLERGY/PARASITIC INFECTION
EOSINOPHILIA
DARK PURPLE, IRREGULAR CYTOPLASMIC GRANULES THAT OBSCURE THE NUCLEUS
BASOPHILS
WBC WHICH ITS GRANULES CONTAIN HISTAMINES
BASOPHILS
ELEVATED BASOPHILS= HEMATOLOGIC DISEASE
BASOPHILIA
RPUND, SLIGHTLY LARGER THAN RBCS NONGRANULAR CYTOPLASM
LYMPHOCYTES
ELEVATED LYMPHOCYTES=VIRAL INFECTIONS
LYMPHOCYTOSIS
LOW LYMPHOCYTES=DRUG THERAPY/IMMUNODEFICIENCY
LYMPHOCYTOPENIA
IMMATURE MACROPHAGE PASSING THE BLOOD
MONOCYTE
SLIGHTLY LARGER DIAMETER THAN OTHER WBCS
NUCLEUS: INDENTED/FOLDED
MONOCYTE
ELEVATED MONOCYTES=INFECTION/INFLAMMATION
MONOCYTOSIS
INCREASE IN WBC ABOVE THE LIMIT
LEUKOCYTOSIS
DECREASE IN WBC BELOW THE NORMAL LIMIT
LEUKOPENIA
DUE TO
-VIRAL INFECTIONS
-TYPHOID FEVER
-MALARIA
-RAD THERAPY
LEUKOPENIA
2-4MM IN DIAMETER
ROUND/OVAL
ANUCLEATE
PLATELETS
PLATELTS ALSO REFERRED TO AS
CELL FRAGMENTS
TRUE BLOOD CELLS THAT MAINTAIN VESSEL INTEGRITY BY INITIATING VESSEL WALL REPAIRS
PLATELETS/THROMBOCYTES
MAJOR CELLS THAT CONTROL HEMOSTASIS
PLATELETS/THROMBOCYTES
SERIES OF CELLULAR AND PLASMA-BASED MECHANISMS THAT SEAL WOUNDS
HEMOSTASIS
ELEVATED PLATELET COUNT=INFLAMMATION/TRAUMA
THROMBOCYTOSIS
LOW PLATELET COUNT=DRUG TREATMENT-LIFE THREATENING
THROMBOCYTOPENIA
EASY BRUISING AND UNCONTROLLED HEMORRHAGE
THROMBOCYTOPENIA
PROCESS THAT ARE EMPLOYED TO DOCUMENT VALIDITY
QUALITY CONTROL
SYSTEM THAT VERIFIES RELIABILITY OF ANALYTICAL TEST RESULTS
QUALITY CONTROL
INSTITUTION, COMPREHENSIVE PROGRAM IN ALL AREAS
TO ENSURE QUALITY
