Matrix Metalloproteinase-1 (MMP-1)
Zinc-dependent interstitial collagenase that initiates the cleavage of fibrillar interstitial collagen types I, II, and III.
Standard vs. Optimal Reference Rangesng/mL
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
<10.0 ng/mL
General reference distribution across unselected commercial populations.
<5.0 ng/mL
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Secreted by senescent fibroblasts and UV-irradiated keratinocytes; cleaves native triple-helix collagen, triggering matrix disassembly.
Differential Diagnosis
Elevated Levels (MMP-1 High)
- •Photo-induced skin aging and solar elastosis
- •Active osteoarthritis cartilage degradation
- •SASP-driven tissue matrix destruction
Low Levels (MMP-1 Low)
- •Preserved interstitial collagen architecture
- •Intact extracellular matrix integrity

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.
Reflexive Testing Protocol:
- Confirmatory testing and secondary biomarker quantification for MMP-1
- Targeted organ system imaging or functional dynamic testing related to interstitial collagenase & matrix degradation
- Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
