Aldolase Test

Aldolase Test – Detailed Guide

The Aldolase Test measures the level of aldolase, an enzyme found in muscles and liver, which helps break down sugars for energy. It is mainly used to assess muscle damage, muscle diseases, and liver disorders.

Why is the Aldolase Test Done?

This test helps diagnose and monitor:

✅ Muscle Disorders

• Duchenne & Becker Muscular Dystrophy (DMD, BMD)
• Polymyositis & Dermatomyositis (Inflammatory muscle diseases)
• Rhabdomyolysis (Severe muscle breakdown)
• Myositis (Muscle inflammation)

✅ Liver Diseases

• Hepatitis (Viral or autoimmune)
• Liver cirrhosis
• Liver damage due to toxins or infections

✅ Other Conditions

• Heart disease (Rare cases of myocardial damage)
• Certain cancers (if affecting muscle tissue)

Test Procedure

🩸 Blood Sample Collection:

• A blood sample is drawn from a vein in the arm
• No fasting required, but avoid vigorous exercise before the test

📅 Results Time:

• Usually available in 1–2 days

Normal Aldolase Levels

What Do Abnormal Aldolase Levels Mean?

🔴 High Aldolase Levels May Indicate:

• Muscle Damage/Diseases:
  • Muscular dystrophy, polymyositis, myositis, rhabdomyolysis
• Liver Disease:
  • Hepatitis, cirrhosis, liver injury
• Viral or Autoimmune Conditions:
  • Systemic lupus erythematosus (SLE), viral infections affecting muscles
• Certain Cancers:
  • If involving muscle or liver

🟢 Low Aldolase Levels Are Rare but can be seen in:

• Advanced muscle-wasting diseases
• Certain metabolic disorders

Next Steps If Aldolase Is High?

🔬 Further Tests May Be Needed:

• Creatine Kinase (CK) Test – Confirms muscle damage
• Liver Function Tests (LFTs) – Checks for liver disease
• Autoimmune Tests (ANA, Anti-Jo-1, ESR, CRP) – Detects inflammatory disorders
• Muscle Biopsy & EMG – For muscle disease diagnosis
