Calculated globulin (CG) is derived from the difference between total protein and albumin results, and forms part of the liver function test (LFT) profile. CG is used widely in primary and secondary care to detect high levels that may indicate haematological malignancy, such as multiple myeloma.

How is globulin measured?

Globulin tests are blood tests. During a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out.

How do you calculate albumin globulin ratio?

The AGR was calculated using the equation AGR=albumin/ (total protein-albumin) and ranked from lowest to highest, the total number of patients being divided into three equal tertiles according to the AGR values.
