Liver function is a measurement of how effectively the liver is functioning.

The liver is the heaviest organ in the body, and is essential to vital life functions such as processing nutrients from food, making bile, removing toxins from the body, and building proteins.

Liver testing helps screen the body for damage caused by over-the-counter medications, hepatitis, and – if you drink – how effectively your organs are managing the accumulated “wear & tear” associated with alcohol consumption.

Liver failure (cirrhosis) is a life-threatening condition, as the human body can only survive for one or two days should the liver shut down completely.


Liver function readings have 2 components: Alanine aminotransaminase (ALT) and Alkaline Phosphatase (ALP).

  • The target reading for ALT is 0 – 45 u/l.
  • The target reading for ALP is 30 – 120 u/l.

When having blood drawn, readings for cholesterol, iron, inflammation, glucose, & kidney function can typically be ordered with the same blood sample as liver function.
