What is a test for nonspecific tissue damage?

A common test for nonspecific tissue damage is the measurement of serum levels of enzymes such as creatine kinase (CK) and lactate dehydrogenase (LDH). Elevated levels of these enzymes can indicate tissue damage due to various causes, including muscle injury, heart attack, or liver disease. Additionally, the presence of inflammatory markers like C-reactive protein (CRP) can also suggest nonspecific tissue damage. These tests help assess the extent of damage but do not pinpoint the exact cause.
