The Diabetes Test Panel is a group of blood tests used to screen for, diagnose, and monitor diabetes and prediabetes. It is often ordered when a person has risk factors, symptoms such as excessive thirst or urination, or is already being treated for diabetes.

What it measures

  • Fasting Glucose — Blood sugar level after not eating for at least 8 hours.
  • Hemoglobin A1c — Average blood sugar over the past 2–3 months.
  • Random Glucose — Blood sugar at any time, regardless of when you last ate.
  • Oral Glucose Tolerance Test (OGTT) — Blood sugar measured before and 2 hours after drinking a sugary drink.

Who it is for

A healthcare provider typically orders this panel for adults with risk factors like obesity, family history, or high blood pressure, and for pregnant women to screen for gestational diabetes.

Preparation

Many diabetes tests require fasting for 8–12 hours; only water is allowed. For an OGTT, you will also drink a glucose solution. If no fasting is needed, your provider will tell you.

Results and what they mean

Results are reported as numbers with reference ranges. A clinician interprets them in the context of your health history; no single result confirms a diagnosis. This is general information, not medical advice—discuss your results with your provider.

Requesting the Diabetes Test Panel in California

Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. With coastal metros, inland towns, and rural counties with very different access to testing, it pays to schedule your collection in advance.

Frequently asked questions

Do I need to fast for this panel?

It depends on which tests are included. Fasting glucose and OGTT require fasting; A1c and random glucose do not. Follow your provider's instructions.

How long does it take to get results?

Typical turnaround is 1–3 business days, but some tests may take longer.

Can I eat or drink during the test?

For an OGTT, you drink a glucose solution and then wait; no other food or drink is allowed until the test is done.

Is this test covered by insurance?

Many plans cover diabetes screening, but coverage varies. Check with your insurance provider.
