What does Kepler's third law imply about planetary motion? Planets further from the Sun orbit at a slower speed than planets closer to the Sun. A planet whose distance from the Sun is 3 A.U. would have an orbital period of how many Earth-years?
Specific IgE (sIgE) Blood Testing (previously and commonly referred to as RAST or ImmunoCAP testing): This test measures levels of specific IgE directed towards foods in the blood. The range, depending upon the laboratory techniques, can go from 0.10 kU/L to 100 kU/L.
Test Overview. An immunoglobulins test is done to measure the level of immunoglobulins, also known as antibodies, in your blood. Antibodies are substances made by the body's immune system in response to bacteria, viruses, fungus, animal dander, or cancer cells. Antibodies attach to the foreign substances so the immune system can destroy them. Antibodies are specific to each type of foreign substance.
