Simple, smarter HCC surveillance that works for more patients

The OncoguardTM Liver test is a sophisticated, yet simple, single blood test delivering high sensitivity and specificity to aid consistent and reliable hepatocellular carcinoma (HCC) detection.

The convenience of accurate blood-based testing helps streamline HCC surveillance, making it easier for patients to follow through with their care.

A unique set of markers clarifies the information

The OncoguardTM Liver test analyzes plasma for methylated DNA markers (MDMs) and serum for the alpha-fetoprotein (AFP).

Methylated DNA markers are a class of biomarkers that may demonstrate aberrant methylation of gene promoter regions, which is common and widespread in HCC cells, even in early stages of the disease.1

High levels of AFP have been shown to be associated with liver diseases, including HCC,2 which is why AFP is the most widely used serological marker to help establish an HCC diagnosis.3

This unique combination of DNA and protein biomarkers employed in the OncoguardTM Liver test exhibits an additive association with HCC.

Sophisticated analysis
Actionable results

The OncoguardTM Liver test uses a sophisticated algorithm combining the patient’s biological sex with results from the analysis of AFP and the MDMs — HOXA1, TSPYL5, and reference B3GALT6 — to generate an actionable qualitative result.

High result

A high test result may indicate the presence of HCC. When a positive result is reported, additional clinical assessment to confirm the presence of HCC is suggested (e.g., diagnostic imaging procedures).

exs-lvr-icon-negative-result

Negative result

A negative test result indicates a lower likelihood of the presence of HCC. When a negative result is obtained, a 3- to 6-month surveillance cadence is suggested.

In rare instances, a technical failure or insufficient clinical material in the sample yields an invalid result.

False positive and false negative results are possible with the OncoguardTM Liver test.4
