What's this test for?

This test is ideal if you're experiencing unexplained blood sugar swings or if you're working to understand how well your body is responding to insulin. It's also useful if you have a history of poor glycemic control and want to figure out whether the issue is related to your insulin treatment or your diet. People being monitored for insulin-producing tumors may also need this test.

What's included in this test?

This test measures a single, specific marker that reflects how your body is managing insulin and blood sugar. It's a targeted single-marker test rather than a broad panel, which makes it useful for zeroing in on insulin-related questions without extra noise from unrelated markers.

What happens after I get my results?

Your results will show up in your online account with the normal range explained next to your value so you can see exactly where you stand. Depending on your result, next steps might include adjusting your diet, timing meals around insulin activity, or retesting after a few weeks to see if levels have shifted. If your value is extremely abnormal, it's a good idea to seek medical care right away. You can download a standard lab report from your account anytime, and the trends feature lets you track this marker over time to see how your levels change.

How can I naturally support healthy insulin response?

Eating more fiber and cutting back on refined sugar and processed carbs can help your body respond to insulin more effectively. Regular physical activity, especially strength training and walking after meals, is one of the most effective natural ways to improve insulin sensitivity. Getting consistent sleep and managing stress also play a big role, since poor sleep and high cortisol can worsen blood sugar control. Small, consistent changes tend to work better than short-term extreme diets.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected at the lab. Once ready, they'll be posted directly to your online account, and you'll be able to view your value alongside the reference range right away.

Who should consider this test?

This test is a good fit for people already managing diabetes or insulin resistance who want more insight into their glycemic control. It also makes sense for anyone whose blood sugar swings unpredictably despite following their diet and treatment plan. People with a suspected insulin-producing tumor may be advised to check this marker as part of a broader workup.

What symptoms indicate I may need this test?

Symptoms like frequent shakiness, sudden hunger, sweating, or confusion between meals can point to insulin swings worth investigating. Unexplained weight changes, fatigue after eating, or blood sugar readings that don't match your expected pattern are also signs. If your glucose numbers stay high or low despite following your treatment plan, this test can help explain why.

What does a high IGFBP-1 result mean?

A higher than normal result often points to lower insulin activity in your body, which can happen when insulin levels are low or your body isn't producing enough. This pattern is sometimes seen alongside poor blood sugar control from the diabetes side rather than the diet side. Retesting and reviewing your recent diet and insulin dosing can help clarify what's driving the change.

What does a low IGFBP-1 result mean?

A lower than normal result usually suggests higher insulin activity, which can happen when the body is producing or receiving more insulin than needed. This is sometimes linked to insulin resistance or overtreatment with insulin medication. Tracking your diet, activity, and insulin timing alongside a retest can help pinpoint the cause.

How often should I retest?

If you're actively adjusting your diet or insulin routine, retesting every few weeks can help you see if those changes are working. Once your levels stabilize, checking every few months is usually enough to keep an eye on things. Using the trends feature in your account makes it easy to spot patterns over time instead of relying on a single result.
