What does a high level of LD Serum in blood work mean?
Lactate dehydronase (LD) is an enzyme that is present in many of your body's tissues and organs (like the brain, liver, heart, red blood cells, and muscles). When a particular organ becomes stressed or ill, perhaps from something like a heart attack or liver failure, your LD serum level would rise, indicating a problem. However, since LD can come from many parts of your body, it is not a test that would tell you that you have a specific problem. Keep in mind that LD is also present in red blood cells, and LD can often be falsely elevated if the blood sample is damaged (like if the sample becomes hemolyzed). So, this test cannot tell you much alone. If you had other blood tests taken with the LD serum level, that would help give you more information. What I would recommend is that you speak to your health care provider about your concerns, so they can help you make sense of this lab result.
Lactate dehydrogenase (LD) is an enzyme, occurred in the cells of most body tissues and organs, especially liver, heart, kidneys etc. When the tissues in such organs are stressed then an individual will have an eminent level of LD in their blood. Its normal level lies in the range 0 to 333 IU/L. Marked rise in LD level is often pragmatic in megaloblastic anemia, untreated pernicious anemia and many other medical condition.
