📌 What is the HBDH Test?
A blood test that measures Hydroxybutyrate Dehydrogenase (HBDH), an enzyme similar to Lactate Dehydrogenase (LDH-1). HBDH is mainly found in the heart, liver, kidneys, and red blood cells and is useful for assessing heart and liver conditions.
📊 Normal Ranges
✔ HBDH (LDH-1): 72 - 182 U/L (varies by lab)
🚨 High HBDH Levels May Indicate:
🔺 Heart conditions (myocardial infarction, myocarditis, heart failure)
🔺 Liver disease (hepatitis, cirrhosis, liver cancer)
🔺 Hemolytic anemia (destruction of red blood cells)
🔺 Muscle diseases or trauma
📉 Low HBDH Levels Are Rare, but may be seen in severe liver dysfunction.
🎯 Purpose of the Test
✅ Diagnoses and monitors heart attacks (myocardial infarction)
✅ Assesses liver disease and damage
✅ Evaluates hemolytic conditions and muscle disorders
✅ Differentiates cardiac vs. liver-related issues in LDH enzyme tests
💡 Key Facts
🔹 HBDH is a marker for heart and liver function
🔹 It is often tested alongside LDH isoenzymes to pinpoint organ damage
🔹 HBDH rises 12-24 hours after a heart attack and stays elevated for up to 10 days
🔹 Helps distinguish between heart and non-heart related LDH elevations
