Assisting in the Analysis of Blood Flashcards
A group of related proteins that function as antibodies.
- They are found in plasma and other body fluids.
immunoglobulins
a measurement of the percentage of packed RBCs in a volume of blood.
- Normal HET varies with age and general 36%-52%
hematocrit
what do lower hematocrit levels indicate?
anemia or bleeding
what do higher hematocrit levels indicate?
dehydration or polycythemia vera
A disorder characterized by an abnormal increase in the number of red blood cells in the blood.
polycythemia vera
A deficiency of hemoglobin in the blood.
- It is accompanied by a reduced number of red blood cells, pale skin, weakness, and shortness of breath, among other symptoms.
anemia
The layer of white blood cells and platelets that separates red blood cells and plasma in a centrifuged sample of whole blood.
buffy coat
Helps in the destruction of parasites and fungi
Eosinophil

- B and T cells combined are the second most abundant WBC in the blood, about 20%–40%
Lymphocyte
produce specific antibodies against a particular antigen
B cells
The oxygen-carrying pigment of red blood cells.
hemoglobin
what is the normal hemoglobin range in a female
12-16 g/dL
what is the normal hemoglobin range in a male
14-18 g/dL
fragments of a larger cell called a megakaryocyte.
- The smallest of the formed elements in the peripheral blood and assists with blood clotting.
Platelets
Plasma is made up of approx. what % of blood volume ?
55%
lab test that measures the rate at which RBC’s gradually separate from plasma and settle at the bottom of a calibrated tube in one hour.
- General indicator/marker for inflammation - ex: RA,lupus,TB
ESR
test that measures the time it takes blood to form a fibrin clot
PT
higher RBC count causes :
Dehydration
performed by hematology
H&H: (Hemoglobin & Hematocrit)
Pale red blood cells. Lacking color.
hypochromic
The study of the form, shape, and structure of an organism or a cell.
morphology
blood test that analyzes the ability of the kidneys to perform their function
Blood urea nitrogen BUN
what panel ?
CPX, Troponin I, Troponin T
Cardiac panel
