What does having a "Low LD Serum" mean?

A fellow caregiver asked...

I recently had a blood test done and it showed that I have Low "LD Serum". Could you please tell me what LD Serum is and how do I raise the LD Serum? Thank you.

LD stands for Lactic Acid Dehydrogenase, which is an enzyme found in many tissues of the body (kidney, heart, muscle, brain, liver). Since it is widely distributed, this is a non-specific test used to determine if a heart attack may have happened. SInce your levels are low, this would mean that there is no heart damage. So, the chances that you had a heart attack are low.

Bottom line: The low serum result is a good result, and not something you want to raise!
