When it comes to liver health, being within the laboratory reference range doesn’t always provide the reassurance we might think.
Many laboratory reference ranges are based on results from apparently healthy populations. But with fatty liver disease affecting approximately 1 in 3 Australian adults, we need to question whether what’s considered statistically normal is always healthy.
Take ALT, a commonly measured liver enzyme. A result of 40 U/L might be considered normal by your laboratory, but lower levels than this can be associated with better liver health.
And importantly, you can have fatty liver disease even when your liver blood tests are completely normal.
⚖️ I’m not an advocate for chasing perfect numbers. But I am an advocate for understanding what those numbers actually mean.
Normal isn’t always healthy. And being within range isn’t always the whole story, especially when it comes to liver health.
