What is a liver function test?

A liver function test is a blood test that measures the levels of various enzymes and proteins in your blood. These substances are produced by the liver, and they can be a sign of liver damage or disease.

There are a number of different liver function tests (LFTs) that can be used to assess the health of your liver. The most common ones are Bilirubin, Alkaline Phosphatase (ALP), Aspartate Aminotransferase (AST), and Alanine Transaminase (ALT).

Bilirubin is a pigment that is produced when the liver breaks down red blood cells. Elevated levels of bilirubin in the blood can be a sign of liver damage or disease.

ALP is an enzyme that is produced in the liver. High levels of ALP in the blood can indicate liver damage or disease.

There are a few different types of liver function tests, but they all basically measure the same thing: how well your liver is functioning. The most common liver function test is called the serum blood panel. This measures the levels of enzymes in your blood that are produced by the liver. These enzymes include:

- ALP (alkaline phosphatase): This enzyme helps with the digestion of fats and is increased when there is damage to the bile ducts.

- ALT (alanine transaminase): This enzyme helps with the breakdown of amino acids and is usually elevated when there is damage to hepatic cells.

- AST (aspartate aminotransferase):

The liver function test is a common medical test that is used to evaluate the health of your liver. The test measures levels of enzymes in your blood that are found mainly in the liver. Enzymes are proteins that help with chemical reactions in your body. When something is wrong with the liver, these enzymes can be released into the blood, where they can be detected by the Liver Function Test. Some of the things that can be checked with this test include hepatitis, cirrhosis, jaundice, and fatty liver disease. It can also give clues about other problems such as an toxins or alcoholism. The test is usually done as part of a routine checkup or when someone has symptoms that might be related to liver.

There are a few different liver function tests that your doctor may order, depending on your individual situation. These tests can help to assess how well your liver is functioning and whether or not there is any damage present.

There are a few different liver function tests (LFTs) that your doctor may order, depending on what they suspect might be going on with your liver. The most common LFT is the alanine transaminase (ALT) test. This measures the level of an enzyme called ALT in your blood. ALT is normally found in liver cells, so high levels of it in your blood can indicate liver damage. Other LFTs that may be ordered include the aspartate transaminase (AST) test, the alkaline phosphatase (ALP) test, and the gamma-glutamyl transferase (GGT) test.  A liver function test is a blood test that measures the levels of enzymes in your blood. These enzymes are produced by your liver and help to break down fats, proteins, and carbohydrates. There are several different types of liver function tests, but the most common one is the alanine transaminase (ALT) test.

ALT is an enzyme that is involved in metabolizing amino acids. When your liver is damaged or inflamed, it releases Jazz hands advertising internships high levels of ALT into your bloodstream. The ALT test can be used to detect liver damage or disease. The normal range for ALT varies depending on your age and sex, but it is generally between 20 and 40 IU/L

There are a number of different liver function tests that can be performed, each of which can give useful information about the status of the liver. The most common liver function tests are the serum glycated albumin test, the serum alkaline phosphatase test, and the serum glutamic-oxaloacetic transaminase (SGOT)test.

The glycated albumin test measures the level of a specific type of sugar (glucose) that is bound to albumin, a protein found in the blood. This test provides an indication of how well the liver is able to process glucose.

The alkaline phosphatase test measures the level of an enzyme that is produced by the liver. This The liver function test is a blood test that measures the levels of certain enzymes and proteins in your liver. These substances are normally present in the liver in small amounts. But if your liver is damaged, these substances can leak into your bloodstream and increase the level of certain enzymes and proteins in your blood.

There are several different liver function tests, each of which measures different enzymes or proteins. The most common liver function tests are the alkaline phosphatase (ALP) test, the aspartate aminotransferase (AST) test, and the alanine aminotransferase (ALT) test.

Replace Junk with Subscription Snack Packs: A Practical Approach to Preventive Nutrition in India

Replace Junk with Subscription Snack Packs: A Practical Approach to Preventive Nutrition in India

India is witnessing a growing shift toward healthier eating habits, yet junk food consumption continues to rise across all age groups. According to ICMR and NFHS-5 data, high-calorie packaged snacks, sugary beverages and deep-fried foods contribute significantly to obesity, diabetes and cardiovascular risk. Replacing these items with nutritious snack alternatives is one of the simplest yet most effective steps toward preventive wellness.

Subscription snack packs offer a structured, convenient and affordable way to transition from unhealthy snacking to balanced nutrition. SecondMedic promotes this approach as part of a broader preventive health ecosystem that focuses on long-term behavioural change rather than temporary diets.

 

Why Indians are Choosing Healthy Snack Subscriptions

1. Convenience in fast-paced lifestyles

Urban and semi-urban households often depend on quick, accessible snacks to keep up with busy schedules. Healthy subscription packs bring pre-portioned nutrition directly to the doorstep.

2. Rising health concerns

India now ranks among the world’s highest in:

  • Diabetes prevalence

  • Childhood obesity

  • Hypertension

  • High cholesterol
     

Replacing junk food is essential for reducing these long-term risks.

3. Growing awareness of clean eating

People are moving toward:

  • Low-sugar

  • Low-sodium

  • High-fibre

  • High-protein

  • Non-fried
    snack alternatives.

     

4. Cost-effectiveness

Contrary to belief, balanced snack packs cost less than repeated purchases of unhealthy packaged foods.

 

What Makes Subscription Snack Packs Healthier?

Healthy snack packs are curated for balanced nutrition:

• Nuts and seeds

Rich in healthy fats, fibre and minerals.

• Millet-based snacks

These snacks reduce cravings while supporting metabolic health.

 

Why Junk Food Needs Replacement

Lacks fibre and elevates glucose rapidly.

• Additives & preservatives

May contribute to long-term digestive and metabolic issues.

Junk foods trigger overeating by stimulating dopamine pathways.

Replacing them with healthier options breaks this cycle.

 

How Subscription Snack Packs Support Preventive Healthcare

1. Portion control

Pre-measured servings reduce the risk of overeating.

2. Balanced nutrition

Snack packs provide fibre, healthy fats and micronutrients missing from typical Indian diets.

3. Reduced decision fatigue
