Your LDH level of 224 is a High LDH level.

An LDH level of 224 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
