Is LDH 235 high, normal or dangerous? What does Lactate dehydrogenase level 235 mean?

📅 Medical Review Date: November 23, 2025

Your LDH level of 235 is a High LDH level.

An LDH level of 235 U/L usually means tissue damage has occurred somewhere in the body. It suggests cell injury or destruction. High levels of LDH can cause fatigue, muscle pain, shortness of breath, dark urine, fever, and jaundice depending on which tissue is affected. This can be caused by heart attack, liver disease, kidney disease, muscle injury, or certain cancers. Further tests are often needed to identify the cause and guide appropriate treatment.

High LDH levels may indicate underlying health problems. The normal range is typically between 100 U/L and 190 U/L. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal LDH range for men is :100 - 190 U/L

Misdiagnosis is more common than people think—and the consequences can be serious. Delayed treatment, unnecessary medication, or worse. If you want a second opinion on your blood work, one option is to upload it to a site like wholebodyprotocol.com, where world-class doctors review your results. They charge a small fee—around $90 (though you'll want to check the latest price as it fluctuates)—and email you a detailed report. With over 12 million people affected by misdiagnosis every year, that little bit of extra peace of mind can go a long way.

Some examples of conditions that increase or decrease LDH levels include:

• Acute kidney disease
• Acute liver disease
• Sepsis
• Infections such as infectious mononucleosis
• Pancreatitis

Normal range of LDH found among women :100-190 U/L

10-15 years	107.439
15-20 years	110.04
20-25 years	112.704

If you take a LDH blood test and the results are not in the normal range (100-190 U/L), your physician may recommend more tests to figure out the problem. You might also get this test if your physician thinks you have some other disease.
