Why is this test performed?
- To measure the levels of albumin, globulin, and albumin globulin ratio
- To evaluate the overall health status
- To diagnose various condition in the body such as kidney, liver, or bone marrow disease
- To diagnose nutritional and metabolic disorders.

- corticosteroids
- Androgens
- Estrogen
- Progesterone
- Growth hormone
- Insulin
- Birth control pills
- What is the normal albumin globulin ratio?
The normal albumin/globulin ratio is slightly greater than 1. Further testing is required to diagnose the cause of abnormal A/G ratio.
- What does a low A/G ratio indicate?
A low A/G ratio may indicate:
- Autoimmune disease
- Kidney disease
- Cirrhosis
- Multiple myeloma
- What are the risks of this test?
Collecting blood from a vein is a very easy procedure and pose only minimum risk, including:
- Bruising

Causes of increased total protein:
- Inflammation
- Infections
- Late-stage liver diseases
- Bone marrow disorders.
You should get tested if you have the following symptoms:
- Symptoms of a kidney, liver, or bone marrow disease
