Two panels on a routine report describe the organs that clear what the body produces. A liver function test explained alongside the kidney panel shows whether those clearing systems are keeping up with the daily load of food, medicines and alcohol. Here is each line in plain language, the pattern Indian doctors now see most often, and what food can do.
What does a liver function test measure?
- ALT (SGPT) is an enzyme that leaks from liver cells when they are under strain. It is the most liver-specific line. Many Indian labs print an upper limit around 40 U/L, and some hepatologists use lower limits for women.
- AST (SGOT) comes from liver, muscle and heart, so it rises after heavy exercise too. An AST higher than ALT is a pattern doctors associate with alcohol.
- GGT is sensitive to alcohol, fatty liver and bile-flow problems; it is often the first enzyme to drift up.
- ALP comes from bile ducts and bone; it rises in children, pregnancy, vitamin D deficiency and bile obstruction.
- Bilirubin is the yellow pigment from recycled red cells. A mild lifelong elevation (Gilbert's pattern) is harmless and common; a new rise with dark urine is not.
- Albumin and total protein are made by the liver. Low albumin is associated with poor protein intake, liver or kidney conditions and long inflammation.
What is the fatty liver pattern in Indian adults?
The commonest reason for a mildly raised ALT in India today is fat stored inside the liver, now called metabolic dysfunction-associated steatotic liver disease (MASLD). It is not an alcohol story; it is a sugar and sitting story, and it appears in people with a normal BMI but a soft waist, the lean Indian pattern. On a report it shows as ALT between about 40 and 100 U/L, often with GGT up, triglycerides above 150 mg/dL, HbA1c creeping towards 5.7% and a waist above 90 cm in men or 80 cm in women. An ultrasound confirms it. The levers are the ones that work for insulin resistance generally: fewer refined carbohydrates, sugar and fruit juice, a 7 to 10 percent weight change where weight is excess, daily movement and, interestingly, regular coffee, which is consistently associated with lower liver-enzyme levels. Farmicine groups this under Impaired Detoxification (B6) and Metabolic Dysfunction (B3).
What does a kidney function test measure?
- Creatinine is a muscle waste product cleared by the kidneys. It rises when filtration falls, but also runs higher in muscular people and lower in the elderly or very slim, which is why it is converted into eGFR.
- eGFR estimates how many millilitres of blood your kidneys filter per minute, using the CKD-EPI 2021 formula. Above 90 is normal; 60 to 89 is mildly reduced and often age-related; below 60 for three months or more is the commonly used definition of chronic kidney disease, and is where a doctor adjusts medicines and nutrient limits.
- Urea (or BUN) rises with dehydration, a very high protein intake and reduced filtration. On its own it is a weak marker; read it with creatinine.
- Uric acid is a by-product of purine breakdown. Above about 7 mg/dL in men and 6 in women is associated with gout, kidney stones and metabolic strain; sugary drinks and fructose raise it as much as meat does.
- Sodium and potassium are the electrolytes; potassium matters most when eGFR is reduced.
Which foods support the liver and kidneys?
- Cruciferous vegetables such as cabbage, cauliflower, broccoli, radish and mustard greens supply compounds that support the liver's detoxification enzymes.
- Garlic, onion, turmeric and beetroot are traditional liver foods with modern support for their antioxidant and bile-flow roles.
- Fibre, 25 to 35 g a day, from pulses, millets, vegetables and fruit, carries bile and its contents out through the bowel.
- Water through the day, enough that urine stays pale, supports the kidneys more than any special drink.
- Moderate, good-quality protein at each meal: dal, curd, eggs, paneer or fish. Very high protein intakes are not a kidney problem for healthy people but are moderated once eGFR falls below 60.
- Less sugar and fructose, which the liver turns directly into fat, and fewer fried and ultra-processed foods.
Two cautions. Paracetamol in high or frequent doses, bodybuilding supplements and unregulated herbal powders are among the commonest causes of liver-enzyme spikes seen in Indian clinics; tell your doctor everything you take. And when eGFR is below 60, potassium-rich foods and supplements, high-dose magnesium and phosphorus need your doctor's guidance, which is why the Bloodwork Reader withholds those suggestions automatically when it sees a reduced eGFR.
What about alcohol?
There is no liver-safe amount, only lower-risk amounts. Indian guidelines broadly echo international ones: no more than two drinks a day for men and one for women, with several alcohol-free days a week, and none at all if enzymes are raised, if triglycerides are high or if you are on medicines that load the liver. A raised GGT with an AST above ALT is the pattern that should prompt an honest conversation. The Detoxification & elimination solution is built around the food steps above, and our guide to reading a blood report shows where these panels sit in the whole picture.
When to see a doctor
See a doctor the same day for yellowing of the eyes or skin, dark tea-coloured urine, pale stools, severe pain under the right ribs, confusion, vomiting blood, or a sudden drop in how much urine you pass. Book promptly if ALT or AST is more than three times the upper limit, if eGFR is below 60 on any report, if creatinine has risen noticeably since last time, if there is blood or froth in the urine, or if you have swelling of the ankles or around the eyes. Anyone with diabetes or high blood pressure should have kidney function and urine albumin checked at least yearly. Food supports these organs; a changing number is for your doctor to investigate.

Frequently asked
What is a normal SGPT (ALT) level?
Most Indian labs print an upper limit around 40 U/L; some clinicians use lower limits, especially for women. A mild rise with high triglycerides and a soft waist is most often associated with fatty liver.
Is an eGFR of 75 a problem?
An eGFR of 60 to 89 is mildly reduced and is often age-related. Doctors look at the trend over time and at urine albumin before reading anything into it.
Can slim people have fatty liver?
Yes. Lean fatty liver is common in Indian adults who carry fat around the waist and eat a lot of refined carbohydrate and sugar, even with a normal BMI.
Does coffee really help the liver?
Regular black or lightly milked coffee is consistently associated with lower liver-enzyme levels and less liver scarring in studies. It supports a good diet; it does not undo a poor one.
