Test Details
Use
Labcorp's NASHnext is a non-invasive blood test that reflects both NASH activity and fibrosis in a single score by combining the results of four individual NASH-associated biomarkers. The intended use of this test is for predicting likelihood of at-risk NASH. (NASH is now referred to as metabolic dysfunction-associated steatohepatitis (MASH)).
Limitations
This test was validated and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
Methodology
NIS4 test produces a score from the results of the following assays:
HbA1c, Whole Blood, Roche;
a2-macroglobulin, serum, Roche;
miR34a, serum RT-qPCR;
CH13L1/YKl40 serum, immunoassay.
