What could cause an elevated LDH?

Answer 1

Elevated LDH levels can mean that you:

(a) are experiencing hemolysis or the breakdown of red blood cells in your body tissues which contain LDH

(b) if your levels remain high for up for several days, it could mean a myocardial infarction (heart attack) is on the way.

(c) If your blood sample was incorrectly handled, the results may show that you have high levels of LDH even if you don't. This may be due to erythrocyte damage.

(d) High levels of LDH may also indicate the presence of cancer cells, which destroy red blood cells found in your body tissues and release LDH into the blood stream.

(e) In empyema, the LDH levels generally will exceed 1000 units per liter. Empyema is when fluid fills your lungs, leading to an infection.

(f) viral meningitis (easily spreads through crowded population, such as college campuses and large urban areas)

(g) encephalitis (caused by moquitoes that carry the disease)
