What's this test for?

This test is ideal if you're experiencing symptoms of low blood sugar like shakiness, dizziness, or confusion, or if you're concerned about insulin resistance linked to weight gain and blood sugar problems. It helps figure out whether your body is making too much or too little insulin, which can explain unexplained blood sugar swings. It's also useful if you've had unusual glucose readings and want a deeper look at what's driving them.

What happens after I get my results?

Your results will be available in your account, with each value's normal range explained so you understand exactly where you stand. Depending on your result, next steps might include adjusting your diet, cutting back on refined carbs and sugar, increasing physical activity, or retesting in a few months to track changes. If your insulin level is extremely high or low along with severe symptoms, seek medical care right away. A downloadable lab report is available in your account, and you can track your insulin levels over time using the trends feature.

Who should consider this test?

This test is a good fit for people with unexplained episodes of low blood sugar, those with a family history of diabetes or metabolic syndrome, and anyone trying to understand stubborn weight gain or fatigue. It's also useful for people already diagnosed with prediabetes or insulin resistance who want more precise tracking. If you've had confusing glucose test results in the past, this test can add clarity.

What symptoms indicate I may need this test?
Common signs include shakiness, sweating, rapid heartbeat, or confusion between meals, which can point to low blood sugar from too much insulin. On the other end, constant fatigue, sugar cravings, weight gain around the belly, and difficulty losing weight can suggest insulin resistance. If you notice these patterns regularly, this test can help identify what's happening with your insulin levels.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. Once processed, they'll be uploaded directly to your secure online account. You'll be able to view, download, and track them at your convenience.
How can I naturally support healthy insulin levels?
Eating fewer processed carbs and added sugars, adding more fiber-rich vegetables, and choosing whole grains over refined ones can help keep insulin steady. Regular exercise, especially strength training and walking after meals, improves how your body uses insulin. Getting enough sleep and managing stress also play a big role, since poor sleep and high stress can both raise insulin levels over time.
What does high insulin mean?
High insulin levels, called hyperinsulinemia, often mean your body is working overtime to manage blood sugar, which is common in insulin resistance and early metabolic syndrome. It can also happen with conditions like insulinoma, a rare tumor that overproduces insulin. Cutting back on sugar, increasing activity, and losing excess weight are practical first steps, and retesting can help you see if these changes are working.
What does low insulin mean?
Low insulin can mean your pancreas isn't producing enough of this hormone, which is seen in some types of diabetes. It can also simply reflect fasting or a very low-carb diet at the time of testing. If low insulin comes with high blood sugar symptoms like excessive thirst or frequent urination, this combination should be checked promptly.
What causes abnormal insulin levels?
High insulin can be caused by insulin resistance, obesity, metabolic syndrome, certain medications, or rare conditions like insulinoma. Low insulin can result from pancreatic issues, certain autoimmune conditions, or simply fasting before the test. Diet, activity level, medications, and even stress can all influence your results, so it helps to note these factors when reviewing your report.
How often should I retest?
If you're making lifestyle changes to manage insulin resistance, retesting every 3 to 6 months can help you track progress. If your levels are normal and you have no symptoms, annual testing is generally enough. Anyone actively working with abnormal results should retest sooner, around 8-12 weeks after starting changes, to see if they're working.

What this means

This result is slightly above the optimal range, which can be an early sign of insulin resistance. It means your body may be producing extra insulin to keep blood sugar under control. This is worth addressing early through diet and lifestyle changes.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
