You need to have enough practical experience with the microscope to be able to use the equipment easily and proficiently. You will also need to practice on yourself and anyone willing to let you practice on them until you feel confident enough in your abilitiy to take a good sample. Then you will need to put everything you have been taught on the training course into practise. Most practitioners are able to start practicing after 3 months, your proficiency will constantly improve as you see more and more clients and get hands-on experience with LBA.
