Lactate Dehydrogenase (LDH) is an enzyme found in most cells of the body and is important in metabolizing carbohydrates and other sources of energy. It catalyzes the conversion of lactate to pyruvate and the reverse reaction of pyruvate to lactate, and can be used as an indicator of tissue damage. Elevated levels of LDH may indicate an increased rate of cell metabolism, inflammation, tissue damage, or certain types of cancer.
LDH can also be used to measure the health of organs such as the heart and liver, as well as to indicate problems with the circulatory system. LDH is an important tool for diagnosing and monitoring conditions, and should be taken into consideration when evaluating a patient’s health.
Why would a doctor test your LDH levels?
Doctors may order an LDH test as part of a routine physical exam or when they suspect certain health conditions. An LDH test can help diagnose conditions such as heart attack, liver disease, and certain types of cancer. It can also be used to check for anemia, which can be caused by a vitamin deficiency, kidney failure, or other medical issues.
An LDH test measures the amount of the enzyme in the blood. The results of the test can provide information about how well certain organs, such as the heart and liver, are functioning. High or low LDH levels can indicate that something is wrong.
A doctor may also order an LDH test to monitor a person’s response to treatment for a specific condition. For example, if a person has anemia, their doctor may order an LDH test to track how well their treatment is working.
In some cases, a doctor may order an LDH test to help diagnose a condition. If the results are abnormal, further tests may be needed to determine the cause.
An LDH test is a simple blood test that can provide a lot of valuable information about a person’s overall health. It is important to get regular check-ups and follow your doctor’s instructions if an LDH test is ordered.
