About this test
How It Works
You collect a small blood sample at home using a finger-prick method in a fasting state. The sample is then sent to a CLIA-certified laboratory for analysis, and your results are delivered digitally once testing is complete, typically 5-10 days.
Dried Blood Spot (DBS) Collection
The test uses a dried blood spot (DBS) sample. A few drops of blood are collected from your fingertip and placed on a collection card, which is then left to dry before being sent to the laboratory.
This method is widely used and offers a convenient alternative to traditional blood sampling.
Preparation Instructions
Collect your sample in the morning after an overnight fast. Avoid eating or drinking (except water) before sampling.
Avoid strenuous exercise prior to testing, as this may influence results.
Who Should Consider This Test
This test is relevant for individuals who want insight into fasting insulin levels and how the body regulates insulin at baseline.
It may be particularly useful when exploring metabolic patterns, energy regulation, or as part of a broader assessment of metabolic health.
Understanding CLIA Certification
Your sample is analyzed in a CLIA-certified laboratory, ensuring that testing is performed according to established U.S. quality standards using validated methods.
Biomarkers included
- Insulin: Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood glucose (sugar) levels. It facilitates the uptake of glucose from the bloodstream into cells for energy or storage. Abnormal insulin levels, either too high or too low, are key indicators of metabolic disorders such as diabetes and insulin resistance.
How to prepare
Fast for 8-12 hours prior to collection. Only water is permitted. It is recommended to collect the sample first thing in the morning.
Frequently asked questions
How accurate is a blood spot test compared to a doctor's office draw?
When collected correctly using the provided card, dried blood spot samples show a strong correlation with traditional venous blood draws for many biomarkers, including insulin. DBS testing is widely used in clinical and research settings as a reliable method for laboratory analysis.
How long do I need to fast before the test?
You must fast (no food or drink except water) for 8 to 12 hours before collecting your sample. Most users find it easiest to collect the sample immediately upon waking for the most accurate at home insulin test results.
