According to the U.S. Centers for Disease Control and Prevention, about 38.4 million American adults have been diagnosed with diabetes. Another 8.5 million adults are estimated to have diabetes but are undiagnosed, while another 96 million people are thought to have prediabetes, a precursor to diabetes. Our blood tests for diabetes deliver the accurate results you need to detect this serious condition, so you can take the necessary steps to safeguard your health.
| Test | What It Measures | Normal Range | Who Should Order |
|—|—|—|—|
| Hemoglobin A1c | 3-month average blood sugar | Below 5.7% normal · 5.7–6.4% prediabetes · 6.5%+ diabetes | Anyone screening for diabetes or monitoring treatment |
| Fasting Glucose | Current blood sugar level | 70–99 mg/dL normal · 100–125 prediabetes · 126+ diabetes | Annual wellness screening |
| Fasting Insulin | Insulin resistance marker | 2–19 mcIU/mL | Anyone with prediabetes, PCOS, or weight gain |
| C-Peptide | Insulin production by pancreas | 0.8–3.1 ng/mL | Distinguishing Type 1 from Type 2 |
| Microalbumin/Creatinine | Early kidney damage from diabetes | Below 30 mg/g | Monitoring diabetic nephropathy |
GLP-1 medications — including semaglutide (Ozempic, Wegovy),
tirzepatide (Mounjaro, Zepbound), and liraglutide (Victoza) — require baseline blood work before starting and regular monitoring during treatment. These are not optional — they are clinically necessary for safe use.
The three essential tests before starting any GLP-1 medication:
Hemoglobin A1c — establishes your baseline blood sugar average. Required to confirm whether GLP-1 therapy is appropriate and to measure treatment effectiveness over time. An A1c above 6.5% confirms type 2 diabetes. Between 5.7% and 6.4% confirms prediabetes — the most common reason GLP-1 therapy is prescribed.
Comprehensive Metabolic Panel (CMP) — checks kidney and liver function before starting. GLP-1 medications are processed by the kidneys and can affect kidney function in some patients. A baseline CMP allows your provider to monitor for any changes.
Lipid Panel — GLP-1 medications significantly improve cholesterol and triglyceride levels in most patients. A baseline lipid panel before starting documents your starting point so improvement can be measured at your next test.
Monitoring labs while on GLP-1 therapy:Most providers recommend retesting A1c every 3 months for the first year to confirm the medication is working. CMP and lipid panel should be repeated at 6 and 12 months. If you experience nausea, vomiting, or abdominal pain — symptoms that can indicate pancreatitis — a lipase test may be ordered.
All three baseline tests are available individually or as a bundle through Personalabs without a doctor’s visit. Order online, visit any Labcorp location, get results in 24–48 hours.
Prediabetes is fully reversible — but only if caught before it progresses to type 2 diabetes. 96 million Americans have prediabetes and 80% of them don’t know it. By the time symptoms appear, many people have already progressed to diabetes.
A1c between 5.7% and 6.4% is prediabetes. At this stage dietary changes, exercise, and in some cases medication can normalize blood sugar completely. A1c of 6.5% or above on two separate tests confirms type 2 diabetes.
The A1c test is the most convenient and reliable prediabetes screening tool available — no fasting required, results reflect 3 months of blood sugar patterns rather than a single snapshot, and it requires just one blood draw.
Who should test for prediabetes:
Adults over 45, anyone with a BMI above 25, people with a family history of diabetes, women who had gestational diabetes, anyone with PCOS, and anyone taking antipsychotic medications or corticosteroids long-term.
Testing annually — or every 3 months if you are actively managing prediabetes through lifestyle changes — gives you the data to know whether your interventions are working.
Diabetes is a metabolic disease marked by elevated blood sugar (or blood glucose) levels. The insulin hormone normally moves glucose from the blood to the cells. Without enough insulin, the body can’t do this job. Patients with type 2 diabetes have insufficient insulin production, while those with type 1 can’t make insulin at all.
Blood work for diabetes can measure blood sugar levels to make sure they fall within healthy levels. If the levels are high, you can talk with your doctor about a diabetes diagnostic and management plan. This can include medication, lifestyle modifications, and regular health checkups.
Diabetes lab tests can be used to help diagnose or monitor the condition. Our Comprehensive Diabetes Profile Blood Test checks several potential disease markers, while our Hemoglobin A1c Blood Test measures your average blood sugar levels over a three-month period to see how well you’re keeping them under control.
If you’ve been asking yourself, “Where can I find diabetes testing near me,” Personalabs has the perfect answer. All you have to do is order your preferred diabetes blood test from us online, then have the testing performed at one of our 4,000+ partner labs nationwide.
You may want to order labs for diabetes if you are experiencing common symptoms of the condition, such as excessive thirst, fatigue, urination, or hunger. Testing is also helpful for anyone with a family history of diabetes or kidney/adrenal diseases, along with lifestyle risk factors such as smoking or lack of exercise.
You should get a blood test for diabetes as soon as possible if you suspect you have symptoms or have a family history. Diabetes left untreated can have dangerous repercussions for your health.

Hemoglobin A1c is the primary test used to diagnose and monitor diabetes. An A1c of 6.5% or above on two separate tests confirms type 2 diabetes. An A1c between 5.7% and 6.4% indicates prediabetes. Fasting glucose above 126 mg/dL on two separate tests also confirms diabetes. The A1c test does not require fasting and reflects average blood sugar over 3 months — making it the most convenient and reliable diabetes screening tool.
Yes. Before starting any GLP-1 medication including Ozempic, Wegovy, or Mounjaro, most providers require a baseline Hemoglobin A1c, Comprehensive Metabolic Panel (CMP), and Lipid Panel. The A1c confirms your starting blood sugar, the CMP checks kidney and liver function, and the lipid panel establishes your cholesterol baseline. All three are available through Personalabs without a doctor’s visit — order online and get results in 24–48 hours.
A fasting glucose test measures your blood sugar at a single point in time — typically after an 8-12 hour fast. It captures your current glucose level but can be affected by recent meals, stress, or illness. Hemoglobin A1c measures your average blood sugar over the past 3 months by looking at how much glucose is attached to your red blood cells. A1c is more reliable for diagnosing and monitoring diabetes because it reflects longer-term patterns rather than a single snapshot.
For general screening, most guidelines recommend testing adults over 45 every 3 years if results are normal. If you have prediabetes, test every 3–6 months to monitor whether lifestyle changes are working. If you are on diabetes medication or GLP-1 therapy, most providers recommend A1c testing every 3 months for the first year then every 6 months once stable.
It depends on the test. The Hemoglobin A1c test does not require fasting — you can eat and drink normally before your blood draw. A fasting glucose test requires no food or beverages except water for 8–12 hours before testing. The Comprehensive Metabolic Panel requires 10–12 hours of fasting. Check the preparation instructions for each test when you order.
Yes. Personalabs provides the physician-approved lab order with your purchase — no referral needed. Order any diabetes test online, visit any Labcorp patient service center near you, and get results in your secure account within 24–48 hours. HSA and FSA eligible.
