Marfan Syndrome-Related Connective Tissue Analysis Panel (Blood)

What This Test Measures

The panel evaluates several blood analytes that reflect structural and functional aspects of connective tissue proteins. Key components may include markers for fibrillin (e.g., fibrillin-1, fibrillin-2), elastin breakdown products, and other proteins involved in tissue integrity. Some tests may also measure enzymes or metabolites linked to extracellular matrix metabolism.

Why It Matters for Marfan Syndrome

Marfan syndrome is caused by mutations in the *FBN1* gene, which affects fibrillin-1—a protein critical for maintaining elastic fibers in connective tissues. Blood tests in this panel help identify abnormalities in fibrillin, elastin, or related proteins that may indicate Marfan syndrome or other connective tissue disorders.

Sample and Preparation

A blood sample (whole blood) is collected via a vein, typically in the arm. The test may use plasma or serum, depending on the specific assays included. No special preparation is needed, but fasting may be required for some components of the panel.

Turnaround Time and Cost

Results are usually available within 3–7 business days, depending on the laboratory. Costs vary by lab and insurance coverage; check with your healthcare provider for details.
