For Live Blood Analysis (LBA), we can use brightfield and darkfield microscopy to look at components in the blood.  The video below is an example of a sample viewed using brightfield with a 60X objective lens that magnifies what we can see by 1200x.  In a live sample we can see red blood cells, white blood cells (immune cells), of which there are many various types such as neutrophils, basophils, eosinophils, and lymphocytes.  We can also see platelet aggregations that can form microclots, we can see fibrin that is part of the clotting cascade.  We can see tiny moving dots that are called chylomicrons and are a result of digesting fats in our food.  We can sometimes see crystals, such as uric acid, or cholesterol, and we can see some types of parasites such as Lyme, or certain types of bacteria. 

There are various anomalies in the blood that can give us an indicaiton of several health issues including: oxidative stress, liver stress, digestive issues, mineral or vitamin deficiencies, toxicity, allergies, immune function and more.
