### What is the Aldolase Test? The aldolase blood test measures the level of aldolase, a protein that helps convert sugar into energy, in your blood. High levels of aldolase can indicate muscle damage. ### How is the Test Performed? 1. **Preparation**: You may need to fast for about 8 hours before the test. Avoid intense exercise for several days prior. 2. **Procedure**: A small needle is used to draw about 1 milliliter of blood from a vein in your arm. The sample is sent to a lab for analysis. 3. **Results**: Results are usually available within a few days. ### Normal Values - **Adults**: 1.0 to 7.5 units per liter - **Children (under 18)**: Up to 14.5 units per liter ### What Do High Levels Mean? Elevated aldolase levels can indicate muscle diseases such as: - **Duchenne Muscular Dystrophy**: A genetic disorder causing muscle weakness, starting in early childhood. - **Limb-Girdle Muscular Dystrophy**: A genetic disorder affecting muscles around the shoulders and hips. - **Dermatomyositis**: An autoimmune disease causing a red rash and muscle weakness. - **Polymyositis**: An autoimmune disease causing muscle weakness in the neck, back, shoulders, and hips. ### Treatment Options Treatment varies depending on the condition but may include medications, physical therapy, and occupational therapy to manage symptoms and improve quality of life.
