Marked increases are usually caused by acute injury to the liver by viruses, shortage of oxygen ischaemia or toxic substances. Gamma-glutamyltransferase GGT levels increase in most liver diseases.

This test is very sensitive, although it also goes up in some heart, lung and kidney conditions. Alkaline phosphatase ALP comes mainly from the cells lining bile ducts and from bones - particularly growing bones.

It rises if there is slow or blocked flow in the bile ducts, if the bile ducts are damaged and in bone disorders. ALP is also raised during the third trimester of pregnancy. The calcium test measures the total calcium in the blood plasma. About half of this is tightly attached to the protein, albumin, which forms the bulk of the protein in your plasma. The calcium level that really counts is the 'free', or unbound, calcium that floats unattached in the plasma.

If you have low albumin levels, the total calcium in your blood will be less; however, because the amount attached to the albumin is reduced because there is less albumin , the actual free levels of calcium may be fine or even raised. Corrected calcium corrects the figure to give the actual, free amount of calcium. Calcium levels are regulated by the kidney, thyroid and parathyroid glands, using the hormones parathyroid hormone, calcitonin and vitamin D. Low levels are uncommon. PT and INR are ways of measuring the ability of your blood to clot.

There is a difference between what you need to do to keep your liver healthy most of the time and what you need to do if your liver is inflamed or damaged.
