Live blood testing, also known as blood nutritional analysis or live cell analysis, uses darkfield microscopy to analyze live blood cells for evidence of nutritional imbalances, parasites, and other health issues. However, there is no scientific evidence to support its effectiveness, and it may be used to sell unnecessary dietary supplements. Valid medical tests are recommended instead. Fraudulent use of live blood testing may be considered a criminal offense.
The live blood test (LBA) is a microscopic test used for the analysis of live blood cells. Also called blood nutritional analysis and live cell analysis, it involves the application of darkfield microscopy. Among proponents, in vitro analysis of blood cells is believed to provide valuable health clues that would not otherwise be gleaned during normal blood tests. It is believed to provide evidence for the presence of nutritional imbalances and parasites, as well as digestive, circulatory and respiratory problems.
In this test, a blood sample is taken from the patient’s fingertip using a sterile lancet. The sample is then placed on a coverslip covered with a coverslip and then immediately viewed under a darkfield microscope. After 24 hours, the blood sample is displayed again.
A dark-field or dark-ground microscope provides contrast in otherwise unstained specimens. The end result is an image in which the field surrounding the sample is dark. Darkfield microscopy is effective in studying unstained biological specimens, especially for tissue cultures and single-celled organisms, such as protozoa. When darkfield microscopy is applied to live blood analysis, blood cells are visualized and monitored by a camera, and conclusions are drawn based on the movement and interaction of these blood cells.
According to several alternative medicine practitioners, live blood testing can provide insight into the presence of vitamin deficiencies, blood toxicity, electrolyte and pH imbalance, immune states, and fungal or yeast infections. Others see it as a tool to detect cancer or degenerative immune diseases. There is no widely accepted scientific evidence that live blood testing can provide data on these conditions. In particular, some alternative medicine experts argue that live blood testing lacks the scientific characteristics of sensitivity, specificity, reproducibility and reliability, all essential for a diagnostic to be effective. Based on these observations, some believe that this practice is a scheme to trick patients into buying unnecessary dietary supplements.
Regulations and penalties have been imposed on the people and laboratories that perform this test. Pretending to diagnose disease with this test is recognized as fraudulent and may be considered a criminal offense in some jurisdictions. People are advised to be conscientious towards healthcare professionals and institutions offering this test. Valid medical tests that can be used in place of live blood testing include complete blood count and differential count, peripheral blood smear, and flow cytometry.
