SerumLDH

Serum Lactate Dehydrogenase (LDH) is a blood test used to measure the activity of the enzyme lactate dehydrogenase in the blood. LDH is an enzyme found in all cells of the body, and its primary function is to convert lactic acid back into pyruvate, a process that helps cells generate energy. Elevated levels of LDH in the blood can indicate tissue damage or cell death, as LDH is released into the bloodstream when cells are damaged or die.

Serum LDH levels can be elevated in a variety of conditions, including:

- Heart attack (myocardial infarction)

- Stroke

- Muscle damage (e.g., from trauma, exercise, or certain medications)

- Liver disease

- Cancer

- Infections

LDH is typically measured in units per liter (U/L) or milligrams per deciliter (mg/dL). Normal LDH levels vary slightly depending on the laboratory, but they are generally considered to be within the range of 135-225 U/L. Elevated levels of LDH can be indicative of various conditions, and further testing may be required to determine the underlying cause.

It is important to note that elevated LDH levels can also be seen in healthy individuals, particularly athletes or those who engage in intense physical activity. In such cases, the LDH levels may return to normal within a few days after the activity.

Serum LDH testing is a simple and non-invasive procedure that can provide valuable information about a person's health status. However, it should be interpreted in the context of the individual's medical history and other test results. If you have concerns about your LDH levels, it is important to consult with a healthcare professional for proper evaluation and guidance.
