Serum or plasma concentration of basic fibroblast growth factor (bFGF)

What Is Basic FGF Used For?

Basic fibroblast growth factor (bFGF) is involved in wound healing, tissue repair, and blood vessel development. Your doctor may order this test if you have symptoms of poor healing, such as slow-healing wounds or chronic inflammation, or if you’re undergoing treatment for conditions like vascular disease.

How Is the Test Performed?

A blood sample is taken from a vein in your arm. The sample is processed into either serum (after clotting) or plasma (using an anticoagulant) and sent to a lab for measurement. Results are typically reported as a concentration value.

What Might Affect Results?

Factors that could influence your bFGF levels include recent trauma, inflammation, certain medications (e.g., steroids), or underlying conditions like diabetes or autoimmune disorders. Avoiding strenuous activity or certain supplements for a few days before testing may help ensure accurate results.

When Might You Need This Test?

Your doctor may recommend this test if you have chronic wounds that don’t heal properly, signs of poor circulation, or if you’re being evaluated for conditions like rheumatoid arthritis or certain cancers that affect tissue growth.
