LDH

You should get an LDH test if your doctor suspects tissue damage from conditions like hemolytic anemia, liver disease, muscle injury, lung disease, or severe infections. It is also recommended for diagnosing and monitoring cancers such as lymphoma, leukemia, and testicular cancer, and for tracking treatment response.

No special preparation is needed for an LDH test, and fasting is generally not required. Avoid strenuous exercise for 24–48 hours before the test, as it can raise LDH levels. Inform your doctor about any medicines or supplements you take, such as alcohol, anesthetics, aspirin, or vitamin C, since these may affect results.

No, fasting is generally not required for an LDH test. You can eat and drink normally before giving your sample. However, avoid strenuous exercise for 24–48 hours beforehand, as it can raise LDH levels. If other tests that need fasting are ordered alongside it, follow those instructions.
