What's this test for?
This test is ideal if you're managing diabetes with insulin injections and want to understand how your body is responding to treatment. It's particularly helpful if you have insulin antibodies that may interfere with standard insulin tests, providing a clearer picture of your actual active insulin levels. People use this test to better understand their blood sugar control and adjust their diabetes management accordingly.
How should I prepare for this test?
You'll need to fast overnight before this test, which means no food or drinks except water for at least 8-12 hours before your blood draw. This fasting period ensures accurate measurement of your baseline insulin levels without interference from recent meals. Be sure to continue taking your prescribed medications unless your doctor advises otherwise, and schedule your test for early morning when possible.
What's included in this test?
This test measures free (bioactive) insulin, which is the portion of insulin in your blood that's actually available to help control your blood sugar. Unlike standard insulin tests, this measurement filters out insulin that's bound to antibodies, giving you a more accurate picture of your body's true insulin activity. This is especially valuable for people on insulin therapy who may have developed antibodies that interfere with regular insulin testing.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your free insulin levels mean for your blood sugar control and diabetes management. These notes include personalized recommendations like dietary adjustments, timing of insulin doses, or whether you should discuss treatment changes with your endocrinologist. You'll also get the standard lab report and can track your insulin levels over time using our trends feature to see how your management strategies are working.
Who should consider getting this test?
This test is specifically designed for people with diabetes who are taking insulin injections and have developed insulin antibodies. If you're experiencing unpredictable blood sugar levels despite careful insulin dosing, or if standard insulin tests don't seem to match your symptoms, this test can provide clearer answers. It's also useful for anyone whose doctor suspects insulin antibodies are interfering with diabetes management.
What symptoms indicate I may need this test?
You may need this test if you're on insulin therapy but experiencing unexplained high or low blood sugar episodes that don't match your insulin doses. Other signs include difficulty achieving stable blood sugar control, inconsistent responses to the same insulin dose, or if your standard insulin test results don't align with your symptoms. This is particularly relevant if you've been on insulin therapy for an extended period.
What is free insulin and why does it matter?
Free insulin is the biologically active form of insulin that's not bound to antibodies in your blood. When you take insulin injections, your body may develop antibodies that attach to the insulin, making it temporarily unavailable to control blood sugar. Free insulin testing specifically measures only the insulin that's actually working in your body, giving you and your doctor a more accurate picture of your true insulin activity for better diabetes management.
How can I naturally support healthy insulin function?
Supporting healthy insulin function involves eating balanced meals with complex carbohydrates, lean proteins, and healthy fats to avoid blood sugar spikes. Regular physical activity, especially after meals, helps your body use insulin more effectively. Managing stress through relaxation techniques, getting adequate sleep, and maintaining a healthy weight all contribute to better insulin sensitivity and blood sugar control.
What does high free insulin mean?
High free insulin levels may indicate insulin resistance, where your body needs more insulin than normal to control blood sugar effectively. This can be a sign of prediabetes, type 2 diabetes, or metabolic syndrome. For people on insulin therapy, elevated levels might suggest you're taking more insulin than your body needs, which could increase the risk of low blood sugar episodes.
How often should I retest my free insulin levels?
If you're being monitored for insulin antibodies or adjusting your diabetes treatment, your doctor may recommend retesting every 3-6 months to track how your body is responding. Once your insulin therapy is stable and working well, annual testing may be sufficient. If you're experiencing changes in blood sugar control or starting new medications, more frequent testing might be needed to ensure optimal management.

What this means
Your free insulin levels are elevated above the optimal range, which may indicate insulin resistance or that your body is producing more insulin to maintain blood sugar control. While this doesn't necessarily mean you have diabetes, it suggests your cells may not be responding to insulin as efficiently as they should, which can increase your risk for metabolic issues over time.
Recommended actions
Focus on low-glycemic foods like whole grains, vegetables, and legumes to reduce insulin demands
Incorporate regular physical activity, especially resistance training, to improve insulin sensitivity
Reduce refined carbohydrates and added sugars in your diet
Consider retesting in 3-6 months along with fasting glucose to monitor trends
* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
