Live blood analysis (LBA), live cell analysis, or nutritional blood analysis is the use of high-resolution dark field microscopy to observe live blood cells in vitro. It is promoted by some alternative medicine practitioners, who assert that it can diagnose a range of diseases.
It provides information about the state of the immune system, possible vitamin deficiencies, amount of toxicity, pH and mineral imbalance, areas of concern and weaknesses, fungus and yeast. Some even claim it can "spot cancer and other degenerative immune system diseases up to two years before they would otherwise be detectable" or say they can diagnose "lack of oxygen in the blood, low trace minerals, lack of exercise, too much alcohol or yeast, weak kidneys, bladder or spleen.
