Krill oil comes from krill, tiny shrimp-like creatures that live in very cold ocean waters. Studies show that krill oil might have health benefits similar to those of fish oil. Krill oil contains EPA and DHA, the same omega-3 fatty acids in fish oil, although usually in smaller amounts. The effects of krill oil have not been researched as thoroughly as those of fish oil. But a few preliminary studies suggest that krill oil could be superior in some ways.
A WBC count is a test that measures the number of white blood cells in your body. This test is often included with a complete blood count (CBC). Your blood contains a percentage of each type of white blood cell. Sometimes, however, your white blood cell count can fall or rise out of the healthy range.
A complete blood count (CBC) gives important information about the kinds and numbers of cells in the blood, especially red blood cells, white blood cells, and platelets. A CBC helps your doctor check any symptoms, such as weakness, fatigue, or bruising, you may have.A CBC also helps him or her diagnose conditions, such as anemia, infection, and many other disorders. A CBC test usually includes: 1  White blood cell (WBC, leukocyte) count. Too many or too few of the different types of white blood cells can help find an infection, an allergic or toxic reaction to medicines or chemicals, and many conditions, such as leukemia. 2  Red blood cell (RBC) count. 3  Red blood cells carry oxygen from the lungs to the rest of the body.
