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.
What It Is. An immunoglobulin E (IgE) test measures the blood level of IgE, one of the five subclasses of antibodies. Antibodies are proteins made by the immune system that attack antigens, such as bacteria, viruses, and allergens. IgE antibodies are found in the lungs, skin, and mucous membranes.
