Elecsys® GAAD

Elecsys® GAAD test for the aid in diagnosis of early-stage HCC

Tune in to help save lives

Heptocellular Carcinoma (HCC) is a "silent killer". It develops unseen, often only to be found when it’s too late to save patients. It is already the third leading cause of cancer death,1 and the global incidence of HCC is increasing, especially in developed countries.2

But it doesn’t have to be that way. We refuse to let it continue as a "silent killer".
We’re turning up the volume on HCC.

Healthcare is rapidly shifting, towards more personalised care that’s more in tune with patients, embracing digital technologies that enable new possibilities. At Roche, we are shaping a new class of diagnostic algorithms.

Introducing the Elecsys® GAAD in-vitro diagnostic multivariate index assay. It will be the only IVD-approved algorithm to help you diagnose early stage HCC and save lives. Combining Elecsys® AFP and Elecsys® PIVKA-II assay results, along with gender and age, Elecsys® GAAD communicates patients’ risk factor clearly, so you may be able to evaluate earlier and save more lives.

It’s simple and intuitive to use, and can be adapted to your current workflow, so there will be no disruption to you.

HCC detection that’s in sync with your workflow

Ending the silence

HCC is often diagnosed in its advanced stages – when 5 year survival rates can be as low as 5%4 – because early stages are asymptomatic, and it can be difficult to gauge each patient’s risk factor. 

HCC develops in patients with chronic liver disease5, but this can happen at any stage over up to 30 years.6 Surveillance measures like ultrasound and MRI are useful, but expensive to keep running. 

Amplifying your confidence

We engineered the Elecsys® GAAD to be truly simple and speedy to set-up and use. However, you’re never alone. We have created a range of support materials to aid your interpretations and ensure that you are always confident in your next step.

Amplifies the effectiveness of AFP

Ultrasound will always be a useful tool in HCC diagnosis. However, it has its limitations; readings can be compromised by obesity, fibrotic changes, and even the quality of device or user experience.7-9

But combining ultrasound with HCC-specific biomarkers, as Elecsys® GAAD does, increases sensitivity for detecting early-stage HCC.10

Instant result of GAAD score

Elecsys® GAAD is a simple yet sophisticated algorithm. 

All you need to do is enter 4 pieces of patient data3 into the calculator, and in an instant you’ll be given a result: a risk-factor score from 0-10, to accurately predict how likely that patient is to develop HCC.3 The score is accompanied by a built-in result interpretation to help guide your next clinical decision.
