|
hemoglobin |
the oxygen carrier that gives red blook cells their colour; composed of four protein (globin) chains. |
|
|
presumptive test |
these cannot confirm that a sample is blood but they can confirm a sample is not blood |
|
|
kastle-meyer |
a colour test that uses phenolpthalein and hydrogen peroxide to react with hemoglobin |
|
|
hematest |
uses benzidine to react with the heme in hemoglobin protein; benzidine + heme = blue precipitate |
|
|
luminol |
reacts with blood to produce a bluish light; chemicals react in the presence of iron in hemoglobin (chemiluminescence) |
|
|
precipitin test |
a test that distinguishes between human and animal blood |
|
|
phenolphthalein |
a chemical used in the kastle-meyer test; turns pink when exposed to hyrogen peroxide and blood |
|
|
serum |
a liquid that separates from clotted blood |
|
|
agglutinate |
an allergic reaction where red blood cells clump together, usually in response to a particular antibody |
|
|
antiserum |
human or animal serum containing antibodies that are specific for one or more antigens |
|
|
serology |
the study of body fluids using specific antigen and serum antibody reactions |
|
|
plasma |
a fluid portion of blood, obtained by centrifuging a sample of whole blood |
|
|
erythrocytes |
red blood cells; contain hemoglobin and transport oxygen from the lungs to the cells and then carries carbon dioxide back to the lungs, where it is exhaled |
|
|
leukocytes |
white blood cells; the primary cells of the immune system and produces antibodies |
|
|
ABO |
a basic classification system for blood types based upon the reaction of antigens and antibodies |
|
|
rh factor |
a basic blood factor, independent of ABO types |
|
|
universal donor |
can give blood to any and all blood types (type O) |
|
|
universal recipient |
can receive blood from any and all blood types (type AB) |
|
|
blood factors |
a specific combination of antigens, enzymes, and proteins in the blood |
|
|
secretors |
people whose blood type antigens are also found in other body fluids |
|
|
thrombocytes |
platelets; clump together to stop blood (reponsible for blood clotting) |
