Liver Function Test Interpretation (LFTs) for Primary Care
A Practical Framework for Interpreting Abnormal Liver Tests in Primary Care
When You Open the Chart and See Abnormal LFTs… What Do You Do Next?
When I first started practicing, abnormal liver tests were one of the labs that slowed me down the most. I remember opening results that were only mildly elevated and still feeling unsure what to do with them. Instead of quickly making a plan, they would sit in my inbox while I looked things up or tried to piece together the right next step.
At the same time, I was caring for patients in an FQHC clinic with chronic liver disease, hepatitis, cirrhosis, and occasionally AST/ALT levels in the thousands. Those results felt much more urgent—and honestly, pretty intimidating.
Over time, once I understood the patterns and the reasoning behind the workup, these labs became much easier to manage. Most of the time, the next step is actually very straightforward when you have a clear framework. This course was designed to share that framework, so when abnormal liver tests show up in your inbox or during a visit, you have a structured way to evaluate them, make a plan, and move forward with confidence.
What you’ll learn:
-
Quickly recognize patterns in abnormal liver tests so you know what you’re looking at
-
Interpret AST/ALT, alkaline phosphatase, and bilirubin with a clear clinical framework
-
Identify when abnormal labs require urgent evaluation vs safe outpatient workup
-
Order appropriate initial testing without unnecessary labs or referrals
Why This LFT Interpretation Course is Different
Most liver education focuses on rare diseases or hospital-level pathology, but in primary care, the challenge isn’t diagnosing every liver disease.
The challenge is knowing:
what pattern you’re looking at
which causes are most likely
what evaluation is appropriate
and when something could be dangerous
This course focuses on how abnormal liver tests actually show up in clinic, including:
Incidental abnormal labs in routine testing
Results ordered by another provider that land in your inbox
Mild abnormalities that need monitoring
Rare but serious presentations you need to recognize quickly
Everything is organized around a simple clinical decision process you can apply in real patient encounters.
What’s Included in This LFT Interpretation Course
This self-paced course includes short video lessons that walk through a clear framework for interpreting abnormal liver tests in primary care. You’ll learn how to recognize common lab patterns, understand the physiology behind those patterns, and apply a structured approach to evaluation and management in clinic.
The course also includes practice cases, downloadable When to Worry Cheat Sheets, and slides for quick reference, and an audio-only playback option through the course app, so you can review lessons while commuting or between clinic sessions.
This activity includes the opportunity to earn 1.75 hours of ANCC continuing education credit upon completion of the post-test and activity evaluation.

Access expires after 1 year with the option to extend access for a nomial fee at the end of the year term. Any downloadable items are yours to keep.
-
You don’t have to purchase both bundles, but many primary care NPs find that lab interpretation and chronic disease management go hand-in-hand.
If you choose both, select the Chronic Care Series — Lab Interpretation Companion so you don’t pay for the renal labs course twice.
Frequently asked questions
-
If you’re looking for a comprehensive approach to interpreting labs in primary care, you may want to consider the Lab Interpretation Series bundle.
The bundle includes this course along with additional modules covering other commonly ordered labs in primary care. Each course focuses on a specific lab panel and teaches a practical framework for interpretation, evaluation, and clinical decision-making.
If you’re primarily interested in learning how to interpret liver function tests, this individual course may be the right fit. But if you want a broader system for approaching abnormal labs across multiple panels, the full Lab Interpretation Series bundle may provide more value.
