noninvasive tools you can use

Online tools can help you understand the risks of liver disease.

Only a doctor can diagnose a liver disease and it is complex but if you, as a patient, are better informed your ability to understand the diagnosis and to ask the right questions will enable you to have a better dialog with your doctor.

Blood tests and screening calculators can't diagnose liver disease for you, but they can be useful to help you understand what your probability of having liver disease might be and may prompt you to consult your doctor even though you may still feel well. Online calculators are available for these screens and they use readily available blood tests and personal characteristics. Nothing personal about you is recorded and is not part of any record so this is just information for you as a patient to be better informed.


Research has shown that the NFS and FIB-4 are useful to help rule out advanced disease.  They can provide some guidance to help you think about it and suggest next steps but they don't prove anything about your possible disease.  From the tables below you can see how they are applied.  They describe high and low cutoffs which have been shown to provide useful guidance about liver status. They are not not ideal but are a guide to suggest broadly how to view liver health and can help point the way to next steps. These are not yet commonly used by your primary care doc but there is a movement underway to make these tests part of determining whether a patient should be quickly referred to a specialist even if there are no symptoms of liver disease.

If you find that you have a high probability of disease it would be wise to see your doctor.  If indeterminate, you need more information.   If your probability is low it is reasonable to be watchful but doesn't suggest that you need to see your doctor soon unless you have symptoms. Any information like this must be weighed in light of all of your other health data as no single snapshot can give you a definitive answer. We offer these to help you understand the general picture as you seek to learn your individual status. Remember advancing liver disease often has no symptoms.
