Serum or plasma concentration of extracellular matrix protein (e.g., related to fibrosis markers)

What This Test Measures

Extracellular matrix proteins are components that support and structure tissues. Elevated levels may indicate abnormal tissue growth or scarring, often seen in diseases like cirrhosis, interstitial lung disease, or other fibrotic conditions. This test may be used to monitor progression or response to treatment in these cases.

Why It’s Ordered

Your healthcare provider may order this test if you have symptoms of organ damage (e.g., fatigue, abdominal pain, shortness of breath) or if you have a known condition linked to fibrosis, such as liver disease, lung disease, or connective tissue disorders.

What to Expect Before the Test

No special preparation is typically needed. You may provide a blood sample (serum or plasma) or, in some cases, urine or other fluids. Follow your provider’s instructions if you’re on certain medications or have dietary restrictions.

What to Expect During the Test

A healthcare professional will draw blood from a vein in your arm. You may feel a slight pinch, but it usually takes only a few minutes. If urine or saliva is involved, you’ll follow standard collection instructions.
