The most common problem is not having the right equipment.
Live blood analysis darkfield microscopes are very specialized so the microscope system needs to be up to the correct specifications to be able to use LBA to its full potential.
We often see practitoners who want to add LBA to their practice, but who don’t want to invest in a good enough system, so they start with a very basic system that doesn’t allow them to see everything they should be able to see with LBA, consequently they and their clients never really fully benefit from LBA.
