Your liver and kidneys work continuously to keep your body functioning properly. The liver processes nutrients, medications, and other substances, while the kidneys filter waste and excess fluid from the blood.
What makes liver and kidney health easy to overlook is that problems do not always cause noticeable symptoms in the early stages. A person may feel completely fine while changes are already appearing in their test results. This is why doctors may recommend routine testing, especially for people with diabetes, high blood pressure, a family history of liver or kidney disease, or other risk factors.
Two common tests are the liver function test and kidney function test. They check how well your liver and kidneys are working and can give useful information about your overall health.
What Are Liver and Kidney Function Tests and Why Are They Important?
A liver function and kidney function test are groups of blood tests used to assess how these organs are working. They may be recommended during a routine health assessment, when symptoms are present, or when someone has a condition that could affect liver or kidney health.
These tests can help doctors:
- Monitor liver and kidney function.
- Identify abnormalities that may need further evaluation.
- Monitor existing liver or kidney conditions.
- Check whether certain medicines are affecting organ function.
- Track changes in health over time.
At Apple Diagnostics, these tests can form part of a broader health assessment, depending on an individual’s health requirements.
It is important to remember that these tests do not always diagnose a specific disease on their own. An abnormal result may require repeat testing or additional tests to understand its cause.
What Does a Liver Function Test (LFT Test) Check?
The liver performs many important functions, including processing nutrients, producing proteins, supporting digestion, and breaking down substances that the body needs to remove.
An LFT test, or liver function test, usually includes several blood measurements. Common parameters may include:
- ALT and AST: Enzymes that may increase when liver cells are injured or irritated.
- ALP: An enzyme associated with the liver and bile ducts.
- Bilirubin: A substance produced when red blood cells break down and processed by the liver.
- Albumin: A protein produced by the liver that provides information about certain aspects of liver function.
- Total protein: Measures the overall amount of protein in the blood.
An abnormal liver test does not automatically mean liver disease. Results can be affected by medications, alcohol consumption, infections, fatty liver disease, and other temporary or long-term conditions.
Doctors therefore interpret LFT results along with symptoms, medical history, medications, and other test findings.
What Does a Kidney Function Test (KFT Test) Check?
The kidneys filter waste products and excess substances from the blood while helping maintain fluid and electrolyte balance.
A KFT test, or kidney function test, generally includes measurements that provide information about how efficiently the kidneys are working. Depending on the test panel, it may include:
- Creatinine: A waste product normally filtered by the kidneys.
- eGFR: An estimate of how efficiently the kidneys filter blood.
- Urea: A waste product that can provide information about kidney function.
- Electrolytes: Sodium, potassium, and other minerals may also be checked.
A kidney test may be recommended for people with diabetes, high blood pressure, a family history of kidney disease, or symptoms that could indicate a kidney-related problem.
As with liver testing, one abnormal result does not necessarily mean kidney disease. Your doctor will consider the result along with your overall health and previous reports.
What Can Abnormal Liver and Kidney Test Results Mean?
An abnormal result does not always indicate serious disease. Dehydration, recent illness, certain medicines, alcohol consumption, and temporary inflammation can affect some liver and kidney markers.
However, persistent or significant abnormalities should not be ignored. For example, consistently elevated liver enzymes or bilirubin may require further evaluation. Similarly, persistently raised creatinine or a reduced eGFR may need closer assessment of kidney function.
The seriousness of a result depends on several factors, including how abnormal it is, whether it continues over time, and whether you have other symptoms or abnormal findings.
Symptoms such as yellowing of the eyes or skin, very dark urine, swelling in the legs, major changes in urination, persistent vomiting, or unexplained weakness should be discussed with a healthcare professional.
When Should You Get a Liver or Kidney Function Test?
A liver function test or kidney function test may be recommended as part of a routine health assessment or when there is a specific reason to evaluate organ health.
Testing may be considered if you:
- Have diabetes or high blood pressure.
- Have a family history of liver or kidney disease.
- Take medicines that require regular monitoring.
- Have unexplained fatigue, swelling, or changes in urine.
- Have previously had abnormal results.
- Have certain metabolic or lifestyle-related risk factors.
At Apple Diagnostics, LFT and KFT tests may also be included in suitable health checkup packages, depending on the package and individual requirements.
Health Checkup Packages for Preventive Screening
A broader health assessment may include several tests, such as blood sugar, cholesterol, complete blood count, thyroid testing, liver function, and kidney function.
Apple Diagnostics offers different health checkup packages for varying preventive screening needs. The most suitable option depends on factors such as age, medical history, symptoms, and existing health conditions.

Get Your Liver and Kidney Function Tests at Apple Diagnostics
Liver and kidney problems do not always cause early warning signs. Appropriate testing can therefore be useful, particularly if you have risk factors or your doctor has recommended screening.
A liver function test and kidney function test can provide valuable information about these organs when interpreted alongside your symptoms and medical history.
If you need blood testing or a broader health checkup in Mumbai, Apple Diagnostics offers pathology and diagnostic services to support your healthcare needs.
Remember that an abnormal report does not automatically mean something serious. Discuss your results with your doctor so they can determine whether repeat testing or further evaluation is necessary.
