Keratinocyte Growth Factor (KGF) – Serum Concentration

What Is Keratinocyte Growth Factor (KGF)?

Keratinocyte Growth Factor (KGF) is a protein produced primarily by cells in the kidneys and lungs. It plays a key role in stimulating the growth and repair of epithelial cells, which line many surfaces in the body, including the skin, digestive tract, and respiratory passages. In medical contexts, KGF can be measured to assess certain conditions affecting these tissues.

Why Might You Need This Test?

Your healthcare provider may order a KGF test if you have symptoms or conditions linked to impaired skin or tissue healing, such as chronic wounds, certain cancers (e.g., lung or head/neck cancers), or autoimmune disorders. It may also be used in research or clinical trials studying tissue regeneration.

How Is the Test Performed?

A blood sample is drawn from a vein in your arm. The blood is then processed to separate serum (the liquid part without clotting factors) for testing. The KGF level is measured using an immunoassay method, which detects the protein’s presence with high sensitivity.

What Do Results Mean?

Results are not typically provided as a single reference range since KGF levels can vary based on health status, disease activity, and treatment. Your provider will interpret results in the context of your medical history and symptoms.
