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.
Because white blood cells (WBCs) naturally accumulate in areas of inflammation, the WBC scan uses radiolabeled WBCs to help determine the site of an acute infection or confirm the presence or absence of infection or inflammation at a suspected site.
