Pancreatic Beta-Cell Function Screening (Serum/Plasma)
This test evaluates the body’s ability to produce insulin in response to glucose, helping assess how well your pancreas’s beta cells function in managing blood sugar levels.

Why This Test Is Done
Doctors may order this test if you have symptoms of diabetes (such as frequent urination, excessive thirst, or unexplained weight changes), a family history of diabetes, or if you’re at higher risk due to obesity, age, or certain health conditions. It can also be used during pregnancy (gestational diabetes) or before certain treatments.
What to Expect Before the Test
You’ll likely fast for 8–12 hours before the test. Bring any medications you’re currently taking, as some may need to be adjusted. Your blood will be drawn from a vein in your arm, similar to other blood tests.
How the Test Works
Your blood sample is analyzed to measure how your body responds to glucose. This involves checking insulin and glucose levels at different times (often before and after a glucose challenge). The results help determine if your pancreas is functioning normally or if insulin production is impaired.
What the Results Mean
Results are interpreted by your healthcare provider based on your medical history and symptoms. Abnormal results may indicate conditions like prediabetes, type 1 or type 2 diabetes, or other metabolic disorders requiring further evaluation.

Frequently asked questions
Early detection of impaired beta-cell function can prevent or delay diabetes complications, such as nerve damage, kidney disease, or cardiovascular issues. It’s also critical for personalized treatment planning, such as medication adjustments or lifestyle changes.
