Book Albumin to Globulin Ratio (A/G Ratio) Test Near Me

An Albumin to Globulin Ratio (A/G Ratio) Test checks the balance of two major blood proteins. It is also called the A:G ratio or albumin globulin ratio. If your doctor ordered this, you can book at participating labs on LabFinder.

What is Albumin to Globulin Ratio (A/G Ratio) Test and what does it show

Some labs list it as a serum protein ratio or A/G. It compares albumin, which helps move fluids and nutrients, to globulins, which include many immune proteins. The ratio can give clues about hydration, nutrition, liver health, kidney health, and immune activity.

Who should get a Albumin to Globulin Ratio (A/G Ratio) Test

Common reasons: check liver or kidney health, look into frequent infections or inflammation, review nutrition concerns or weight loss, monitor known conditions, or follow up on results from a comprehensive metabolic panel or total protein test. Your doctor may pair it with other blood tests for a fuller picture.

How long does a Albumin to Globulin Ratio (A/G Ratio) Test take and what to expect

You will check in and confirm your order. A phlebotomist cleans your arm and takes a small blood sample. A bandage goes on and you can head out. Most visits take about 10 to 20 minutes from arrival to finish.

Is a Albumin to Globulin Ratio (A/G Ratio) Test safe and what are the risks

Yes, this is a quick, routine blood draw and is considered very safe. You might feel a quick pinch, notice a small bruise, or feel a little lightheaded for a moment afterward, but those effects usually fade quickly. Be sure to tell the staff if you take blood thinners, have a bleeding disorder, or if you have fainted during blood draws before. They will take extra care to keep you comfortable. Recent IV fluids or extreme dehydration can change protein levels, so let the team know.

How to prepare for a Albumin to Globulin Ratio (A/G Ratio) Test

Ask about fasting: some providers prefer a fasting sample, so follow your order. Hydrate normally: drinking water helps with the draw. Avoid heavy meals right before: a very large, fatty meal can nudge some lab values. Take medicines as directed: unless your doctor says otherwise. Bring prior results: they help the lab and your doctor compare trends. Always follow any instructions from your doctor or the lab.

Related conditions a Albumin to Globulin Ratio (A/G Ratio) Test may help evaluate

Liver problems, kidney disease, infections or ongoing inflammation, autoimmune conditions, nutrition problems, and certain blood or protein disorders. Results are interpreted in context. Your doctor will review your numbers along with your history and symptoms before suggesting next steps.
