Non-invasively aids in the detection, staging, and monitoring of liver fibrosis for nonalcoholic steatohepatitus (NASH) patients.

Introduction to NASH

Nonalcoholic steatohepatitis (NASH) affects approximately 25 million people in the US.1 In 2019 NASH was the second leading indication, and the indication increasing with the fastest rate, for liver transplantation.2 Currently, biopsy is the gold standard for the diagnosis of NASH. However, biopsy may be subject to sampling problems that can confound the results, in addition to surgical costs, risk, and inconvenience for the patient.

Identifying High-Risk NASH Patients is Imperative
  • F3-F4 stage of liver fibrosis has been identified as the most significant independent risk factor for mortality in NASH patients3,4
  • NASH-related cirrhosis is becoming a more common indication for liver transplantation3
  • Progression of NASH-related liver fibrosis is 2 times faster than nonalcoholic fatty liver disease5

PROMETHEUS FIBROSpect NASH is a laboratory-developed test that aids in in the detection, staging, and monitoring of liver fibrosis in nonalcoholic steatohepatitis patients. The simple blood test is noninvasive and provides a quantitative fibrosis score to help physicians risk stratify and monitor patients based on 3 clinically relevant biomarkers.

Proprietary NASH-specific algorithm
  • Differentiated F0-F2 from F3-F4 liver fibrosis in clinically diagnosed NASH patients9
  • Validated with samples from 396 biopsy-confirmed NASH patients9
  • Provides quantitative liver fibrosis test results
FIBROSpect NASH benefits:
  • Easy-to-read and interpret test result
  • Noninvasive and non-fasting
  • Can be repeated frequently, easily, and safely
  • May reduce the need for biopsy
