Millions of people in the United States have liver disease. Your physician may have diagnosed you with Chronic Liver Disease (CLD) or at high risk of having CLD. There are regular blood tests for liver function (AST, ALT, alkaline phosphatase, bilirubin, albumin, and prothrombin time/INR) which are important for assessing liver health but are not very sensitive. The HepQuant DuO™ test provides information on liver function problems early and at all stages of the disease. The HepQuant DuO test will help your doctor check and keep track of your liver’s health, function, and any liver diseases or disorders you may have.
HepQuant DuO Addresses Critical Questions in Care
The HepQuant DuO Test Process
After arriving at your physician’s office or designated blood collection site, to begin the HepQuant Duo test, you will be asked to drink a solution that contains a naturally occurring substance that is found in your body called cholate. Twenty minutes after consuming the cholate drink, 3 mL (approximately 0.6 teaspoon) of blood will be collected. Then, forty minutes later a second blood collection will occur.
After the last blood draw, the lab will prepare your samples and send them to the HepQuant lab in Colorado, via overnight delivery. The test results will be sent directly to your physician in about two weeks. Be sure to schedule a follow-up appointment with your doctor to review the results.
The HepQuant DuO test measures how well your liver clears the cholate from your blood. The result of the lab analysis of your blood samples is a number called the Disease Severity Index (DSI). Your doctor will use the DSI produced from the HepQuant DuO test, along with other test results, to assess your liver function and give you advice on how to care for your liver.

HepQuant DuO Test FAQ
Cholate is a naturally-occurring substance that your body makes from cholesterol. It is made in your liver and helps you digest and absorb the fat in your diet. You have from 1000 to 3000 milligrams of cholate in your body. The HepQuant DuO test administers 40 milligrams of labeled cholate in the drink you consume at the beginning of the test.
The full test takes about 1 hour. After the test is complete, you can resume taking any medications, supplements, and eating and drinking as normal.
Your doctor will recommend how often you should have a HepQuant DuO test.
The Disease Severity Index (DSI) is based on your liver’s ability to clear cholate from the blood. DSI increases as liver disease progresses. Your doctor will explain the results of your DSI and other test results. Ask your doctor if you have more questions about your HepQuant DuO test results.
The test result is used in combination with results from other standard blood tests, imaging tests, and other measures of liver disease to help your doctor decide how much follow-up and treatment you may need and whether you need to undergo more invasive procedures, like screening endoscopies.
