The Science
No medical degree required. Just two numbers, one blood test, and the willingness to listen.
Their doctor probably hasn't mentioned it. It doesn't make headlines. It doesn't get talked about at dinner parties.
But GGT — Gamma-Glutamyl Transferase — is one of the most sensitive early warning systems your body has. It's a liver enzyme. When it's elevated, your liver is under oxidative stress. When it's very elevated — your liver is on fire.
Mine was 216 U/L in September 2025. The reference range is under 60. I was well past the warning. I was in the red zone.
This is what most people — including many professionals — miss. The liver doesn't just process what you drink. It regulates inflammation, manages cholesterol, controls blood pressure, filters every toxin that enters your body.
When the liver is under chronic stress, the heart feels it. Portal hypertension. Cardiovascular strain. Systemic inflammation.
That helicopter over the Southern Ocean wasn't just a liver story. It was the bill arriving for years of ignoring the early warnings.
The good news? The liver is the most regenerative organ in the human body. Given the right conditions — it heals. Fast.
Know Your Numbers
Primary Marker
Gamma-Glutamyl Transferase
GGT is your liver's stress alarm. It's an enzyme found primarily in liver cells, and it rises when those cells are under oxidative stress — from alcohol, fatty liver, inflammation, or chronic toxic load.
It's sensitive. It moves early. Which makes it your best early warning system — long before more serious damage shows up on other tests.
A high GGT is your liver whispering. A very high GGT is your liver shouting. Mine was shouting at 216 U/L.
Secondary Marker
Alanine Aminotransferase
ALT measures actual cell damage. Where GGT tells you the liver is stressed, ALT tells you cells are dying. It's a deeper level of the story.
When ALT normalizes — like mine did to 22 U/L in March 2026 — it means the active hepatocellular death has stopped. The fire is out. The repair has begun.
Biological stability. That's what the numbers say. The chemical fire extinguished.
You don't need to wait for symptoms. You don't need to feel sick. You just need a blood test.
In New Zealand a liver function test — including GGT and ALT — is available through your GP. It is cheap, fast, and covered. Most results are back within 24 hours.
