Globulin Test
Reviewed
Globulins are a group of proteins in your blood that play an important role in liver and kidney function, blood clotting, and fighting infection. This test measures globulin levels to help diagnose various conditions.
Preparation and collection
You may need to stop taking certain medicines before this test, so tell your provider about everything you take. But don't stop taking any medicines unless your provider tells you to. If your globulin test is part of another blood test, you may need to fast (not eat or drink) for several hours before the test. Your provider will let you know if there are any special instructions to follow.
Understanding this test
Use the reference interval and units printed by the laboratory that performed the test. A result outside that interval is not a diagnosis by itself, and a result inside it does not rule out every condition. Your symptoms, history, medicines, timing, and related tests can change what the result means.
- Abnormal results can be caused by certain medicines, dehydration, pregnancy, or other conditions.
- This test alone does not diagnose a specific condition; it is used along with other tests and your symptoms.
- There is very little risk to having a blood test, but you may experience slight pain or bruising at the needle site.
What to do next
Talk with your provider to learn what your results mean. They will consider your symptoms, medical history, and other test results to determine if further evaluation is needed.
