What do liver function tests measure?
Liver function tests are blood tests that measure substances the liver makes or processes, including enzymes, proteins and bilirubin.
Enzymes, proteins and waste products
A panel usually includes ALT, AST, alkaline phosphatase, bilirubin, albumin and prothrombin time. Some show how well the liver works; others hint at damage. MedlinePlus explains each test.
Why one abnormal number isn’t a diagnosis
These tests alone usually can’t diagnose a specific disease, so abnormal results often lead to more testing. A high alkaline phosphatase can come from bone disease, and results after a recent illness may be temporary, so the clinician may repeat them. See your liver panel results, one line at a time.
✅ Patient Action: Ask the ordering clinician: “Which tests are we following, and what pattern would make you call me?”
What bilirubin, albumin and INR show in cirrhosis
Bilirubin, albumin and INR each reflect a different liver job.
| Test | What it reflects | Key Clinical Detail |
|---|---|---|
| Bilirubin | A waste product the liver removes | Higher: one clue to cirrhosis; jaundice is the visible sign |
| Albumin | A protein the liver makes | Lower: another clue to cirrhosis |
| INR | How fast blood clots | Higher means slower clotting; liver disease is one cause |
Sources: MedlinePlus, prothrombin time and INR; NIDDK, Diagnosis of Cirrhosis (reviewed June 2023).
🔬 How It Works: Prothrombin is a clotting protein the liver makes. When blood clots slowly, the INR runs higher.
INR is also used to monitor warfarin, so the team reads it alongside any blood thinner. For why albumin drops, see what a low albumin result means.
✅ Patient Action: Ask the hepatologist: “Which of these three should I log, and what change should make me call?”
What is a MELD score and does it matter for you?
A MELD score estimates how urgently an adult needs a liver transplant, using blood tests.
📊 Clinical Data Point: MELD scores range from 6 to 40, and the U.S. has used MELD 3.0 since July 2023. Source: UPMC Transplant, “Understanding Your MELD Score”; OPTN/SRTR 2023 Annual Data Report.
What MELD measures and why it exists
It was adopted in 2002 to rank waiting-list candidates by near-term risk of death rather than time waited (Clinical Liver Disease, 2013). MELD 3.0 uses bilirubin, INR, creatinine, sodium, albumin and sex.
Why a kidney test appears in a liver score
Creatinine is included because kidney problems are a major complication of end-stage liver disease (OPTN/SRTR 2023). Transplant candidates receive the score, so you may never hear it.
✅ Patient Action: If a transplant evaluation begins, ask the transplant coordinator: “What is the current MELD score, and when are new tests needed?”
Symptoms that matter more than any lab number
Report these changes to the care team whatever the latest labs showed.
Confusion or sleep changes
Early hepatic encephalopathy can look like sleep changes, mild confusion, forgetfulness or mood changes. MedlinePlus advises contacting the provider about any change in mental state, since it can worsen quickly into an emergency. Dehydration, infection, constipation and sedating medicines can trigger it.
Bleeding, black stools or vomiting blood
NIDDK says people who vomit blood or have black or bloody stools should go to a hospital right away. It also lists easy bruising or bleeding as a worsening sign.
Swelling, yellowing and dark urine
Ascites (belly swelling), swollen ankles, jaundice, severe itching and dark urine complete NIDDK’s cirrhosis symptom list.
⚠️ Clinical Warning: If your loved one is hard to wake or unresponsive, call 911. Severe hepatic encephalopathy can progress to unconsciousness.
✅ Patient Action: Ask the hepatologist: “Which changes should I call about the same day, and which mean the ER?”
Medicines, supplements and food: ask before changing
Check every new product with the care team first, including those sold without a prescription.
Over-the-counter pain relievers and sleep aids
NIDDK advises talking with the doctor before giving prescription medicines, NSAIDs, acetaminophen or sleep aids. Sedating and narcotic pain medicines can worsen confusion, so tell every prescriber about the liver diagnosis. For overdose signs, see acetaminophen liver damage symptoms and when they start.
Supplements and herbal products
NIDDK also advises asking before dietary, herbal or complementary products.
Eating: small, frequent meals and a dietitian
NIDDK says to avoid going too long without food; the team may suggest meals every 3–4 hours while awake. Avoid raw or undercooked shellfish, fish and meat, and stop alcohol completely. The doctor may limit sodium or suggest a registered dietitian.
✅ Patient Action: Ask the pharmacist: “Which pain reliever, if any, is acceptable, and what is the daily limit?”
A lab log and questions for the care team
A simple log turns scattered results into something a clinician can use.
What to write down after each blood test
Record the date, test, result, the lab’s printed range, new symptoms, and any medicine or supplement change. Clotting-test results can vary between labs and methods, so copy the range from each report.
Questions to ask at the next visit
- Which results are we tracking, and why?
- Which changes should prompt a same-day call?
- Is a MELD score being calculated?
Looking after yourself
In a 2022 study of 25 caregivers of people with decompensated cirrhosis, burden was significant, and lack of self-care time, hepatic encephalopathy and strict diet rules were common stressors (Hepatology Communications). Ask the care team what caregiver support they offer.
Caregiver liver disease lab questions
1. Which lab tests should a caregiver track for someone with liver disease?
A caregiver of someone with liver disease can log ALT, AST, alkaline phosphatase, bilirubin, albumin and INR; ask the care team which matter most.
2. Can liver function tests alone diagnose liver disease?
No. Liver function tests alone usually can’t diagnose a specific disease, so abnormal results often lead to more testing.
3. Does an abnormal liver test always mean liver disease?
No. A high alkaline phosphatase can come from bone disease, and results after recent illness may be temporary, so the test may be repeated.
4. What does a high bilirubin level mean in liver disease?
Bilirubin is a waste product the liver removes. Higher levels are one clue to cirrhosis; ask the hepatologist what the result means.
5. What does low albumin mean in cirrhosis?
Albumin is a protein the liver makes. Lower levels are one clue to cirrhosis; ask the care team what the result means.
6. What does a high INR mean in liver disease?
A higher INR means slower clotting, and liver disease is one cause. Ask the care team how to read it, especially on blood thinners.
7. What is a MELD score?
A MELD score estimates how urgently an adult needs a liver transplant, on a 6–40 scale. The transplant coordinator can explain a specific score.
8. Which symptoms mean I should call the liver care team right away?
Report confusion, sleep changes, easy bleeding, belly or ankle swelling, jaundice or dark urine to the care team; ask which need a same-day call.
9. When should I call 911 for someone with cirrhosis?
Call 911 if your loved one is hard to wake or unresponsive. NIDDK says vomiting blood or black stools need a hospital right away.
10. Can I give over-the-counter pain relievers to someone with cirrhosis?
Ask the doctor or pharmacist first about NSAIDs, acetaminophen and sleep aids; NIDDK advises this before any over-the-counter medicine in cirrhosis.
11. How can a caregiver avoid burnout while tracking liver labs?
Caregiver burden in cirrhosis is significant, and lack of self-care time is common. Ask the care team what caregiver support they offer.
Your next step this week
Start the log before the next blood draw, and write three questions for the care team. Numbers help, but the symptoms in this guide are what call for a quick phone call. If you are caring for someone with liver disease, you do not have to read every result alone.
