Pro-Insulin is a precursor of insulin, an essential hormone that helps regulate glucose (sugar) levels in the blood. In the pancreas, pro-insulin is converted into insulin and C-peptide. Measuring pro-insulin levels can provide insight into how well the pancreas produces and secretes insulin.
Testing pro-insulin levels is particularly useful for people at risk of diabetes, or for those who wish to improve their diabetes management. It can assist in the early detection of insulin resistance and the assessment of pancreatic function before diabetes fully develops.
Pro-Insulin levels provide insight into the insulin production capacity of the pancreas. Normal levels indicate healthy insulin production and release, while abnormal levels may point to nascent problems with blood sugar regulation.
A high pro-insulin level may indicate insulin resistance, an early indicator of type 2 diabetes. It may also suggest an overload of the pancreatic beta cells, which are working hard to produce more insulin in response to increased blood glucose levels.
A low level may indicate a diminished capacity of the pancreas to produce insulin, which is typical for later stages of diabetes or following damage to the pancreas. It may also be a sign of effective treatment or dietary control in people with diabetes.
Answers to what people usually want to know.
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.
It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
We work with 1,000+ collection points across the Netherlands. After ordering you'll see which locations near you are available and you pick where you'd like to go.
