Evidence-based components of a corporate liver screening panel
Based on longitudinal health screening data, a comprehensive liver panel includes ALT (SGPT) and GGT. While ALT is a primary marker for liver inflammation, GGT identifies alcohol-related liver stress and bile flow issues that may be missed by ALT alone. Screenings are most effective when paired with clinical follow-up pathways, such as dietary consultations and scheduled repeat testing.
- Core test: ALT/SGPT; the primary blood marker for liver damage and fatty liver.
- Add if missing: GGT; catches alcohol-related liver stress that ALT alone can miss.
- Clinical protocol: A defined follow-up pathway for abnormal results, including specialist referrals.

Why liver screening can't wait until 40
Pazcare's Employee Health Matters Handbook, built from over 77,000 claims and 12,000+ health checkups, found that 12.4% of everyone screened had an abnormal ALT result; the primary blood marker for liver damage and fatty liver. For men in their early 30s specifically, that number rises to 22.4%. More than 1 in 5. For women the same age, it's 6.4%.
An abnormal ALT means the liver is leaking enzymes because its cells are being damaged, most commonly from fatty liver, driven by diet, alcohol, or metabolic syndrome. Left unaddressed, fatty liver progresses to inflammation, then scarring, then cirrhosis. The handbook notes males account for 75% of liver flags, and these are typically fatty liver, not alcohol-related.
These employees don't have a disease yet. They're on a path toward one, and the screening data is picking it up years before it would ever show up as a claim.

What a complete liver panel actually tests
ALT / SGPT
Alanine Aminotransferase (ALT), also called SGPT (Serum Glutamic Pyruvic Transaminase), is the primary marker checked in checkup packages that test for liver health and inflammation. It's the number the Handbook's data above is built on.
GGT (Gamma-Glutamyl Transferase)
GGT helps detect liver stress specifically linked to alcohol use or bile flow problems; a category of liver stress that ALT alone can miss. The Handbook's specific recommendation: add GGT to the panel if it isn't already included, especially for the 20-40 age group, which shows the highest abnormal-ALT rates.
Standard companion markers
Most standard liver function test (LFT) panels also include AST, bilirubin, and albumin alongside ALT: these give a fuller picture of liver inflammation and function, though the Handbook's own data specifically tracks ALT and recommends GGT as the priority addition.
The gap: what most checkup packages miss
Data analysis reveals two primary gaps in corporate screening: the exclusion of GGT from standard panels and the absence of integrated follow-up protocols for abnormal results. Pazcare's dataset shows that liver and digestive conditions account for 6.83% of claims, with liver-specific admissions averaging ₹1.1 lakh per case. These costs are often associated with advanced disease stages that were detectable through earlier screening and intervention.
That's the trajectory an abnormal ALT result in a 30-year-old employee is quietly on, if nothing happens after the test.

Why an abnormal result needs a follow-up pathway, not just a report
The Employee Health Matters Handbook outlines a standardized protocol for addressing abnormal ALT levels: a dietary consultation within 30 days, repeat testing at 90 days, and a gastroenterologist referral if levels remain elevated. This structured approach converts diagnostic data into a preventive health outcome.

What to ask your employee health checkup provider
If you're evaluating or renewing a preventive health checkup for employees, these are the specific questions to ask about liver screening:
- Panel scope: does the liver panel include ALT and GGT, or just ALT?
- Follow-up protocol: Does the provider offer a structured pathway (consultation, repeat testing, or referral) for abnormal results?
- Age coverage: Is liver screening included for employees in their 20s and 30s, or only offered to employees over 40?
- Confidentiality: Are individual results kept private from HR, with only aggregate, anonymized trends shared at the organization level?
- Turnaround time: How quickly are results and any recommended consultation available after the test?
Quick Glossary: Understanding Medical Terms
- Liver Function Tests (LFTs): Think of these as a 'report card' for your liver. They measure certain chemicals in your blood to see how well your liver is doing its job, like cleaning your blood and helping you digest food.
- ALT (or SGPT): This is a specific enzyme that lives inside your liver cells. Think of it like a liquid inside a balloon; if the liver gets irritated or hurt, the 'balloon' leaks, and this enzyme spills into your blood. Finding a lot of it is a red flag that your liver is stressed.
- GGT (Gamma-Glutamyl Transferase): A specialized alarm system that catches liver stress, especially from alcohol or bile flow issues, which the main alarm (ALT) might miss.
- AST: Another enzyme similar to ALT. Doctors look at it alongside ALT to get a more complete picture of what is happening inside your liver.
- Bilirubin: A waste product your liver filters out. If your liver isn't working perfectly, this builds up in your body, which can mean the liver's 'filter' is clogged.
- Albumin: A protein your liver makes. A healthy liver makes plenty of it; low levels might mean the liver is struggling to do its job.
- Fatty Liver: This happens when too much fat builds up in your liver cells. It's like a computer running too many programs at once and slowing down; the liver is working, but struggling to keep up.
- Cirrhosis: The most serious stage of liver damage. If the liver is hurt for a long time, it develops hard, scar-like tissue that makes it very difficult for the liver to work properly.
