Hepatocyte growth factor (HGF) serum

Test Code: 30142

Cpt Code:

83520 (x1)

Clinical Utility

For the quantitative measurement of Hepatocyte growth factor (HGF). HGF is a potent mitogen for hepatocytes, leading to organ regeneration and wound healing. HGF levels have been shown to be elevated in various liver diseases, reflecting liver damage and dysfunction.


The assay for quantification of HGF is a sandwich ELISA performed in a microtiter plate format. Conversion of a chromogenic substrate produces a color, the intensity of which is proportional to the concentration of HGF in the sample material. A standard curve is used to calculate the concentration of HGF in each of the test samples. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.

Assay Range

The result is reported in ng/mL. The assay range is approximately 0.6 to 24 ng/mL. The reference range for a healthy population is less than 1.0 ng/mL. However it should be noted that these ranges are obtained from a limited population of apparently healthy adults and are not diagnostic thresholds.

Causes For Rejection

Invalid specimen type, inadequate volume, gross hemolysis or gross lipemia, sample not frozen upon receipt.

Turnaround Time

Test performed M,W,F. TAT 3 - 5 days from receipt of specimen.
