Question | Answer |
---|---|
Hematocrit abbreviation | Hct |
Hemoglobin abbreviation | Hgb |
Hematocrit recorded value | % (percent) |
Hemoglobin recorded value | g/dL |
Hematocrit to Hemoglobin comparison | Hct is approximately 3 times greater than Hgb or Hgb is approximately 1/3 of Hct. (Eg. Hct of 33% = Hgb of 11 g/dL) |
Hematocrit definition | The percentage of red blood cells in a sample |
Buffy coat | The thin light colored line above the red blood cells after a blood sample has been centrifuged in a capillary tube |
What diagnostic term may be used if the hematocrit and hemoglobin are below normal range? | Anemia |
What diagnostic term may be used if the Hct and Hgb are above the normal limits? | Polycythemia vera |
ESR is the abbreviation for... | erythrocyte sedimentation rate |
Hct normal ranges | Adult Female: 36-45% Adult Male: 42-52% Neonates: 44-64% Infants: 37-41% Children: 35-41% (Values may vary slightly from different reference range resources) |
Hgb normal ranges | Adult Female: 12-16 g/dL Adult Male: 14-18 g/dL Neonates: 17-23 g/dL Infants: 9-14 g/dL Children 10-15 g/dL (Values may vary slightly from different reference range resources) |
RBC normal ranges | Adult Female: 4-5.5 million/mm Adult Male: 4.5-6 million/mm Neonates: 4.8-7.1 million/mm Infants: 3.8-5.5 million/mm Children 4.5-4.8 million/mm (Values may vary slightly from different reference range resources) |
WBC normal ranges | Adult Female: 4000-11000/mm Adult Male: 4000-11000/mm Neonates: 9000-30000/mm Infants: 6000-16000/mm Children 5000-13000/mm (Values may vary slightly from different reference range resources) |
Five different white blood cell in order of highest to lowest number in healthy individual | Neutrophil segmented (50-65%), Neutrophil bands (0-7%), Lymphocyte (25-40%), Monocyte (3-9%), Eosinophil 1-3%), Basophil (0-1%) |
Red cell indices normal values | MCH 82-99 fl MCH 26-34 pg MCHC 31-37 g/dL |
Sed Rate (ESR) normal values (Westergren) | Female under age 50:0-20 mm/hr Male under age 50: 0-15 mm/hr Female over age 50: 0-30 mm/hr Male over age 50: 0-20 mm/hr |
Erythryocyte sedimentation rate tests for....... | Inflamation (May be due to any cause of inflammation such as infection, rheumatoid arthritis, tuberculosis, hepatitis, cancer, multiple myeloma, rheumatic fever, lupus erythematosis) |
The ESR is allowed to sit undisturbed to allow the cells to fall out of the plasma for exactly what period of time?q | One hour |
Another term for thrombocyte | Platelet |
Granulocytes (granular appearance of cytoplasm) | NeutroPHIL, eosinoPHIL, basoPHIL |
Agranulocytes (clear appearance of cytoplasm) | MonoCYTE, LymphoCYTE |
