LDH Test Overview and Results

If your doctor has recommended an LDH (Lactate Dehydrogenase) test, you might be wondering what it is, why it’s needed, and what the results mean. Don’t worry; this guide will explain everything in simple terms so you can understand the test and its significance for your health.

What is an LDH Test?

The LDH test measures the level of Lactate Dehydrogenase (LDH), an enzyme found in almost all body tissues. LDH plays a crucial role in energy production by helping convert sugar into energy. When cells are damaged or destroyed, LDH is released into the bloodstream, which is why high levels may indicate tissue damage or disease.

Why is the LDH Test Done?

Doctors order an LDH test to:

• Check for tissue damage (e.g., liver, heart, muscles, lungs, or kidneys).
• Monitor diseases like anemia, infections, or cancer.
• Assess the severity of conditions like heart attack, liver disease, or lung disorders.
• Track the progress of chemotherapy in cancer patients.

What Are the Symptoms That May Require an LDH Test?

You might need this test if you experience:

• Unexplained fatigue or weakness
• Muscle pain or cramps
• Shortness of breath (possible lung or heart issues)
• Jaundice (yellowing of skin or eyes) (liver problems)
• Dark urine or pale stools (possible liver or kidney issues
• Persistent nausea or vomiting

How is the LDH Test Performed?

The test is simple and involves:

1. A small blood sample taken from your arm.

2. No fasting is usually required, but follow your doctor’s instructions.

3. Results are typically available within a day or two.

Understanding LDH Test Results

LDH levels are measured in units per liter (U/L). Normal ranges may vary slightly between labs, but generally:

• Adults: 140–280 U/L
• Children: Higher levels (varies with age)

What Do High LDH Levels Mean?

Elevated LDH suggests tissue damage or disease, such as:

• Heart attack (damaged heart muscle releases LDH)
• Liver disease (hepatitis, cirrhosis)
• Muscle injury (trauma, intense exercise)
• Lung diseases (pneumonia, pulmonary embolism)
• Blood disorders (hemolytic anemia)
• Certain cancers (lymphoma, leukemia)

What Do Low LDH Levels Mean?

Low LDH is rare but may occur due to:

• Excessive vitamin C intake (rarely a concern)
• Genetic conditions affecting LDH production
• Your doctor will interpret the results based on your symptoms and other tests.

How Can You Manage Abnormal LDH Levels?

Since high LDH indicates an underlying condition, treatment depends on the cause. However, you can support your health by:

• Eating a balanced diet (rich in fruits, vegetables, and lean proteins)
• Staying hydrated (helps kidney and liver function)
• Avoiding alcohol and smoking (reduces liver and lung stress)
• Managing chronic conditions (diabetes, heart disease)
• Following prescribed treatments (if diagnosed with an illness)

When Should You See a Doctor?

Consult your doctor if:

• You have persistent symptoms like fatigue, pain, or jaundice.
• Your LDH results are abnormal and need further evaluation.
• You’re undergoing cancer treatment and need monitoring.
