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.

Busting Nutrition Myths in India: An Evidence-Based Guide Powered by SecondMedic’s AI Health Guide

Nutrition misinformation has become increasingly common in India. From viral social media diets to generational food beliefs, many individuals struggle to separate fact from fiction. These myths can influence daily habits, delay proper treatment and contribute to the growing burden of lifestyle diseases.

SecondMedic’s AI Health Guide was designed to offer clarity. By analysing scientific literature, Indian dietary patterns and personal health inputs, it explains complex nutrition topics in a human-friendly, practical manner. This blog explores the most widespread nutrition myths in India and how an AI-enabled approach helps users make informed dietary decisions.

 

Why Nutrition Myths Persist in India

1. Cultural dietary traditions

Food practices often evolve through experience but not always through evidence. Certain long-held assumptions continue despite scientific updates.

2. Rise of viral misinformation

Millions of Indians search diet advice online daily, and misleading content spreads rapidly without expert review.

3. High prevalence of lifestyle diseases

ICMR and NFHS-5 highlight escalating rates of:

  • Diabetes

  • Obesity

  • Hypertension

  • PCOS

  • Thyroid disorders
     

The public seeks quick solutions, making myths appealing.

4. Limited access to qualified dietitians

Many people rely on hearsay or generic tips rather than personalised nutrition guidance.

SecondMedic’s AI Health Guide bridges this gap by offering accessible, evidence-backed explanations.

 

Myth 1: “Carbohydrates always lead to weight gain.”

Carbohydrates are not inherently harmful.
The problem lies in refined carbohydrates like white bread, sugary drinks and packaged snacks.

What the science says

Whole grains, millets, oats and fibre-rich carbs improve:

  • Gut health

  • Blood sugar regulation

  • Energy levels
     

Research in Lancet Public Health confirms that complex carbs support metabolic wellbeing.

AI Health Guide perspective

The system evaluates:

  • Activity level

  • Blood sugar trends

  • Dietary preferences
     

Then recommends the type and quantity of carbs suitable for the individual.

 

Myth 2: “Protein damages the kidneys.”

This is one of India’s most common misconceptions.

Clinical reality

Protein affects kidneys only in individuals with existing kidney disease.

NFHS-5 shows that most Indians do not meet their daily protein requirement.

Balanced approach

Safe protein sources:

  • Lentils

  • Paneer

  • Eggs

  • Tofu

  • Chicken

  • Fish
     

An AI-guided nutrition plan ensures intake matches needs and health conditions.

 

Myth 3: “All fats are unhealthy.”

Fats play essential roles in:

  • Hormone production

  • Brain function

  • Vitamin absorption
     

Good fats

  • Nuts and seeds

  • Olive oil

  • Flaxseed

  • Fatty fish
     

Harmful fats

  • Trans fats

  • Hydrogenated oils

  • Deep-fried packaged snacks
     

SecondMedic’s AI Health Guide analyses dietary logs to suggest healthier fat alternatives.

 

Myth 4: “Detox diets cleanse the body.”

Detox teas, juices and cleanses are popular but not scientifically validated.

Actual detoxification

The liver, kidneys and digestive system naturally remove toxins.

Risks of extreme detox diets

  • Fatigue

  • Digestive distress

  • Slow metabolism

  • Nutrient deficiencies
     

A sustainable alternative includes balanced meals, hydration and fibre-rich foods.

 

Myth 5: “Eating after 8 PM causes weight gain.”

Timing is not the primary factor.
Weight gain depends on:

  • Total calorie intake

  • Food quality

  • Portion control

  • Sleep-wake cycles
     

For shift workers or late diners, an AI-based guide personalises eating windows that match biological rhythms.

 

How AI Personalises Nutrition Guidance for India

The AI Health Guide adapts advice based on:

• Clinical inputs

Blood reports, symptoms, chronic conditions.

• Lifestyle signals

Sleep, activity, stress, work schedules.

• Cultural eating patterns

North Indian, South Indian, vegetarian, non-vegetarian diets.

• Personal health goals

Weight control, energy improvement, disease management.

This ensures that the guidance is not generic-it is tailored for real-life Indian scenarios.

 

How an AI Health Guide Supports Preventive Healthcare

1. Early risk identification

AI recognises patterns that may indicate:

  • Rising blood sugar

  • Nutrient deficiencies

  • Poor digestion

  • Inflammatory markers
     

2. Behavioural nudges

Small, realistic changes are suggested instead of extreme diet plans.

3. Improved health literacy

Users understand why certain foods are better choices.

4. Better medical support

Clear explanations enhance doctor and dietitian consultations.

 

Conclusion

Nutrition myths can lead individuals toward restrictive diets, nutrient deficiencies and misguided health decisions. With rising lifestyle diseases in India, accurate nutrition knowledge is essential. A scientific, personalised approach-supported by an AI Health Guide-helps individuals navigate misinformation confidently.

By combining evidence-based insights with individual dietary needs, SecondMedic’s AI-driven guidance empowers people to adopt sustainable, preventive and truly health-enhancing food habits.
