Description
Matrix Metalloproteinase-9 (MMP-9) is an enzyme involved in the breakdown and remodeling of extracellular tissue. It plays an important role in inflammatory processes, immune system signaling, wound healing, and vascular function. Elevated MMP-9 levels may indicate increased inflammatory activity and have been associated with various chronic inflammatory conditions.
Clinical Utility
MMP-9 testing may be useful in the evaluation of individuals with:
- Chronic inflammatory symptoms
- Suspected mold or biotoxin exposure
- Chronic fatigue
- Persistent respiratory complaints
- Autoimmune disorders
- Chronic pain syndromes
- Complex chronic illness presentations
Physiologic Role
MMP-9 is involved in:
- Tissue remodeling and repair
- Regulation of inflammatory responses
- Immune cell migration
- Vascular permeability
- Extracellular matrix degradation
Elevated MMP-9 Levels May Be Associated With:
- Chronic inflammatory response syndromes
- Biotoxin and mold-related illness
- Autoimmune diseases
- Cardiovascular disease
- Chronic infections
- Respiratory inflammatory conditions
Specimen Requirements
Specimen: Blood (plasma)
Fasting: Fasting is not required for this test.
Important Considerations
MMP-9 is a nonspecific marker of inflammation and tissue remodeling. Results should be interpreted in conjunction with clinical findings, patient history, and other laboratory studies. MMP-9 is frequently utilized as part of a comprehensive assessment of inflammatory and immune system function.
