A liver cancer blood test may help support screening conversations for people at higher risk of hepatocellular carcinoma (HCC), the most common type of primary liver cancer. MoleculeDx focuses on blood‑based testing for early liver cancer detection and is designed to help eligible patients and providers take the next step with physician‑guided follow‑up.

Traditional surveillance often relies on ultrasound and basic lab markers that can miss early‑stage disease—especially in patients who feel well and have no obvious symptoms. A more advanced, multi‑signal liver cancer blood test aims to close that gap.

What Is a Liver Cancer Blood Test?

A liver cancer blood test is a laboratory test that analyzes a blood sample for biological signals associated with liver cancer. Historically, this has focused on a single marker such as alpha‑fetoprotein (AFP), a protein produced by the liver. Elevated AFP levels can sometimes indicate HCC, but AFP alone detects only about 40–60% of cases and can remain normal even when cancer is present.

Newer approaches, like MoleculeDx, go beyond a single marker. Instead of looking only at one protein, the test examines multiple biological signals in the blood, including cancer‑specific fusion gene transcripts linked to early‑stage HCC.

In simple terms:

• Older tests look at one data point
• Multi‑signal tests like MoleculeDx look at many data points together, using AI to interpret the pattern

The goal is to detect liver cancer earlier, when it is still small, potentially curable and before symptoms appear.

Who May Need Liver Cancer Screening?

Not everyone needs a liver cancer blood test. Screening is generally focused on people with higher‑than‑average risk, including those who:

• Have cirrhosis (scarring of the liver) from any cause
• Live with chronic hepatitis B or hepatitis C
• Have non‑alcoholic fatty liver disease (NAFLD) or NASH, especially with advanced fibrosis
• Have a strong family history of liver cancer
• Have other chronic liver conditions identified by their physician

For these high‑risk groups, professional guidelines often recommend regular surveillance, typically every 6 months, to catch HCC early.

In reality, many patients:

• Miss imaging appointments
• Live far from centres with high‑quality ultrasound
• Struggle with repeated hospital visits and long wait times

A liver cancer screening blood test that can be done from home—like the one offered by MoleculeDx—may make it easier for these patients to stay on top of their screening plan.

How MoleculeDx Supports Early HCC Detection

MoleculeDx was designed specifically for early liver cancer detection using a blood‑based, multi‑signal approach. It is built on the proprietary Fusion‑detect™ AI genomics platform, which has been trained and refined using data from tens of thousands of patient samples.

Instead of relying on AFP alone, MoleculeDx:

• Detects nine specific fusion gene transcripts associated with HCC
• Uses next‑generation sequencing (NGS) to read these cancer‑linked signals in a blood sample
• Applies a multi‑layer AI model to classify a patient’s risk of having liver cancer

Clinical validation data show:

• Overall accuracy: about 95%
• Sensitivity: about 94% (probability of correctly identifying cancer when it is present)
• Specificity: about 95% (probability of correctly identifying when cancer is not present)

By contrast, traditional tools such as AFP and ultrasound alone perform significantly lower for early disease. The MoleculeDx liver cancer blood test is therefore positioned as a more precise and informative screening option for high‑risk patients—particularly those for whom standard tests may be inconclusive or difficult to access.

How the MoleculeDx Testing Process Works

MoleculeDx was built to fit into real life. The process is designed to be simple for both patients and clinicians.

Step 1: Check eligibility and book

Patients or physicians start by visiting the MoleculeDx website and checking whether the individual meets basic high‑risk criteria (such as cirrhosis, hepatitis B/C or NAFLD/NASH). If eligible, a liver cancer blood test appointment can be booked online.

• Many patients can schedule an at‑home blood draw, choosing a date and time that works for them.
• In some locations (for example, through partner health systems), a walk‑in option may also be available.

Step 2: At‑home blood collection

A certified phlebotomist visits the patient at home, takes a standard blood sample and ships it to the MoleculeDx lab via controlled cold‑chain logistics.

• No hospital visit is required
• The visit typically takes less than 15 minutes
• This is particularly helpful for older adults, those with limited mobility or patients who live far from major centres

Step 3: AI‑powered analysis

In the lab, MoleculeDx uses its CLIA‑certified processes to extract and analyze the fusion gene transcripts in the blood. The Fusion‑detect™ AI engine then evaluates multiple signals together to determine whether the pattern is more consistent with high or low risk of HCC.

Step 4: Results in about 24 hours

Patients receive a secure, digital report—typically within 24 hours of the blood draw—showing whether the test result suggests low risk or elevated risk of liver cancer at the time of testing.

If the result is concerning, the report encourages follow‑up with a physician for additional imaging, specialist referral or further evaluation as appropriate.

What Results Can and Cannot Tell You

A liver cancer blood test like MoleculeDx provides important information, but it is not a stand‑alone diagnosis or a replacement for medical judgment.

What a liver cancer blood test can tell you

• Whether your blood sample shows a pattern of fusion gene activity consistent with higher or lower risk of HCC
• Whether you may need further evaluation, such as ultrasound, CT/MRI or specialist consultation
• Whether your risk profile is changing over time when the test is repeated under physician guidance

What it cannot tell you

• It does not confirm the exact size, location or number of tumours
• It does not replace the need for imaging when cancer is suspected
• It does not give treatment recommendations—that still requires a physician and, often, a multidisciplinary care team

In other words, a liver cancer screening blood test is best used as a decision‑support tool—one that helps patients and physicians decide when further investigation is needed.

When to Speak With a Physician

You should always discuss liver cancer screening with a healthcare professional, especially if any of the following apply to you:

• You have been diagnosed with cirrhosis
• You live with chronic hepatitis B or C
• You have NAFLD/NASH and your doctor has mentioned advanced fibrosis or cirrhosis
• You have a family history of liver cancer or other strong risk factors
• You have abnormal liver tests or imaging results and want a more detailed assessment

A physician can:

• Confirm whether you meet criteria for high‑risk surveillance
• Help you understand if the MoleculeDx liver cancer blood test is appropriate for you
• Interpret your results in the context of your full medical history and imaging
• Arrange follow‑up imaging or specialist care if needed

FAQs

Can liver cancer be detected by a blood test?
Yes, liver cancer can sometimes be detected by a blood test, especially when advanced molecular methods are used. Traditional tests like AFP miss many early cancers, but multi‑signal blood tests that analyze fusion gene transcripts and other biomarkers have shown much higher accuracy for early HCC detection.

Is a blood test a replacement for imaging?
No. A liver cancer blood test is meant to support early detection and surveillance—not replace ultrasound, CT or MRI when those are needed. Abnormal blood test results should be followed by imaging and specialist evaluation.

Who is considered high risk for liver cancer?
High‑risk groups typically include people with cirrhosis (from any cause), chronic hepatitis B or C, advanced NAFLD/NASH, and those with a strong family history of liver cancer. Your physician can confirm your personal risk level and recommend a screening plan.

How do I book the MoleculeDx test?
You can start by visiting the MoleculeDx website, checking your eligibility and booking a liver cancer blood test appointment online. In many cases, a phlebotomist can come to your home for the blood draw, and results are delivered digitally in about 24 hours.
