Description
Why It’s Done:
• To assess tissue damage: The LDH test is commonly used to evaluate potential damage to organs and tissues, including the heart, liver, kidneys, muscles, and lungs. Conditions like heart attacks, liver disease, kidney disease, and muscle trauma can elevate LDH levels.
• To monitor certain diseases: LDH levels can help monitor the progression of diseases such as hemolytic anemia (destruction of red blood cells), muscular dystrophy, or cancer, particularly lymphoma and leukemia.
• **To evaluate heart conditions: LDH can be used to monitor heart-related conditions, particularly after a heart attack, as the enzyme is released when heart muscle cells are damaged.
• To track treatment effectiveness: In cases of disease or tissue damage, the LDH test can be used to track the effectiveness of treatment and determine if the condition is improving or worsening.
• **To diagnose conditions like liver disease: Conditions such as hepatitis or cirrhosis can elevate LDH levels, helping doctors diagnose and manage liver-related conditions.
Preparation:
• Fasting: Fasting is not typically required for the LDH test. However, it’s always a good idea to follow any specific instructions from your healthcare provider.
• A blood sample will be drawn, usually from a vein in your arm.
• Medications: Inform your healthcare provider about any medications or supplements you are taking, as certain medications (e.g., statins, alcohol, or antibiotics) can affect LDH levels.
• Avoid strenuous activity: Intense physical activity can sometimes increase LDH levels temporarily, so it may be recommended to avoid heavy exercise before the test if possible.
• No special preparation: In general, there are no strict lifestyle changes or dietary restrictions needed before the test, unless instructed by your healthcare provider.
