AI Summary Liver complication testing finds problems caused by advanced liver disease, mainly ascites (abdominal fluid) and hepatic encephalopathy (HE, brain changes). Doctors start with symptoms and an exam, then add ultrasound, diagnostic paracentesis, blood tests such as albumin and ammonia, and cognitive tests. No single result confirms HE, so doctors read results together. Other checks cover varices, kidney problems, and liver cancer. Call your care team about a swollen abdomen or new confusion; sudden, severe confusion needs immediate care.

Liver complication testing covers the tests doctors use when liver disease causes problems beyond the liver itself. The two main groups look for ascites, a buildup of fluid in the abdomen, and hepatic encephalopathy (HE), a change in brain function that happens when the liver cannot clear toxins from the blood.
This page explains why these tests are ordered, what each one checks, what to expect, and how to think about results. Your care team reads results together with your symptoms and medical history.

ASCITES AND HE DIAGNOSIS
Doctors group these tests by the problem they look for. Each group has its own page with the individual tests.
Ascites is fluid that collects in the abdomen. It develops when high pressure in the liver's blood vessels (portal hypertension) combines with low levels of the protein albumin. Testing confirms that fluid is present, then checks what the fluid contains to look for infection and guide care.
Hepatic encephalopathy is brain dysfunction caused by the liver's inability to remove toxins from the blood. It can bring brain fog, memory lapses, sleep changes, and disorientation. Doctors rely on your history, symptoms, and an exam, and add blood tests, ammonia levels, imaging, and cognitive tests to support the diagnosis or rule out other causes. HE is treatable and often reversible.
SYMPTOMS AND WARNING SIGNS
Complication testing usually starts with a change you notice or a finding from a routine visit. Here are common reasons.
Growing abdominal size, a sense of fullness, weight gain, or swelling in the ankles and legs can point to ascites. A physical exam can diagnose moderate to severe ascites. Ultrasound, kidney and liver function tests, and urinalysis often follow.
Brain fog, irritability, trouble finding words, disorientation, or a sleep schedule that flips between night and day can be signs of hepatic encephalopathy. A family member or caregiver often notices these changes first.
Doctors perform a diagnostic paracentesis in anyone with new grade 2 or 3 ascites, and in anyone hospitalized for a cirrhosis-related complication. The goal is to check the fluid for infection early.
Cirrhosis can lead to ascites, bleeding from varices, hepatic encephalopathy, and jaundice. Doctors call this stage decompensated cirrhosis. Ongoing monitoring helps your team catch problems sooner.
TEST COMPARISON GUIDE
Each test answers a different question. Your doctor chooses based on your symptoms and history.
| Test | What it checks | How it is done |
|---|---|---|
| Physical exam and ultrasound | Whether fluid has collected in the abdomen, and where | Hands-on exam; ultrasound imaging |
| Diagnostic paracentesis | Cell count, protein, albumin, and bacterial cultures in abdominal fluid | Needle removes a fluid sample |
| Serum albumin | Albumin in your blood. Low albumin is one cause of ascites | Blood draw |
| Ascitic fluid albumin | Albumin in the abdominal fluid itself | Measured on the paracentesis sample |
| Ammonia level | Ammonia in the blood, a waste product the liver normally clears | Blood draw |
| Neurocognitive testing | Attention, speed, and thinking skills that may be subtly affected | Paper-and-pencil tasks, computer tasks, or brain-wave recording (EEG) |
Ascites and hepatic encephalopathy are often diagnosed from symptoms and an exam first. Tests confirm the diagnosis, look for a cause, or rule out other problems.
LAB RESULTS EXPLAINED
Reference ranges differ between labs, so ask your care team how your numbers compare with the lab's range.
One result rarely tells the whole story. Your doctor combines fluid tests, blood tests, your symptoms, and your exam.
TESTING DAY GUIDE
Most complication tests are quick. Paracentesis is the only one that uses a needle to collect fluid.
Ask your care team about any instructions before your visit, such as whether to fast before blood tests.

Ascites and hepatic encephalopathy are two of several complications of advanced liver disease. Your doctor may also check for these.
Portal hypertension can enlarge blood vessels in the esophagus or stomach. These are called varices, and they can bleed. A doctor can look at them directly with an endoscope.
Hepatorenal syndrome is a severe form of kidney failure that happens in advanced cirrhosis. Low blood sodium (hyponatremia) is also a common problem that worsens outlook. Kidney function tests and blood chemistry help check for both.
Cirrhosis raises the risk of liver cancer. Regular imaging helps find changes before symptoms appear.
Common Questions
Liver complication testing is the group of tests that look for problems caused by advanced liver disease, mainly ascites (abdominal fluid) and hepatic encephalopathy (brain changes). It includes exams, blood tests, fluid tests, and cognitive tests.
A diagnostic paracentesis is a short procedure that removes a small sample of abdominal fluid with a needle. The fluid is tested for cell count, protein, albumin, and cultures. Your skin is numbed first, and most people go home the same day.
Not always. Ammonia is one piece of information. A normal level helps rule out hepatic encephalopathy, but a high level alone cannot confirm it. Doctors diagnose overt HE mainly from your symptoms and exam.
Yes. Covert hepatic encephalopathy involves subtle thinking changes that a routine exam can miss. Psychometric tests or an EEG can detect them, and finding them early matters because they predict overt HE.
Call your care team if you notice a growing abdomen, new swelling, or new confusion. Seek immediate medical attention for sudden, severe confusion. Your team can decide which tests you need.
