Why do I need an LDH isoenzymes test?You may need this test if your health care provider suspects that you have tissue damage based on your symptoms and/or other tests. An LDH isoenzymes test is often done as a follow-up to a lactate dehydrogenase (LDH) test. An LDH test also measures LDH levels, but it doesn't provide information on the location or type of tissue damage.
