Low Lactate dehydrogenase (LDH): what it means
A Lactate dehydrogenase (LDH) result below the normal range is considered low. Here is what a reduced Lactate dehydrogenase (LDH) can point to, and when it is worth discussing with a doctor.
Reference range: ~140–280 U/L in most labs; a non-specific marker of cell turnover, interpreted in context

- Not clinically significant — a low LDH has no established disease meaning.
When to discuss with a doctor
LDH is almost never interpreted alone — its value is as part of a pattern. A high LDH with low haptoglobin and high reticulocytes points to haemolysis and prompts a cause hunt. In a known lymphoma or germ-cell tumour, LDH is tracked to gauge bulk and response. An isolated mildly raised LDH with no symptoms is often an artefact or non-specific and is repeated in context. Mediora.AI shows LDH alongside the haemolysis markers and flags the pattern rather than the number in isolation; deciding what a raised LDH means belongs with your doctor, who reads it with the rest of the picture.
