InsideTracker Sleep blood test - 10 blood values

InsideTracker gives members a Sleep score from 0 to 100, calculated from a fixed set of blood values. If you search for InsideTracker in the Netherlands, you usually want those values measured without a membership and without shipping a sample to the United States.

This blood test is that alternative: the same blood values behind the Sleep category, drawn at a certified Dutch lab and returned digitally in your account, with an assessment by a BIG-registered doctor.

This panel may suit people who want to see what sleep does to their body, or what their body does to their sleep. It can be relevant for:

• People who sleep poorly for a long time and want an objective picture, alongside their GP's advice
• People working irregular or night shifts
• People who want to check their magnesium and vitamin D status
• People who want the InsideTracker Sleep category measured in the Netherlands

This panel measures 10 blood values:

• Blood sugar regulation: Fasting Glucose, Fasting Insulin, HbA1c and the calculated HOMA-IR index, because sleep deprivation lowers your insulin sensitivity.
• Minerals and vitamins: Magnesium and Vitamin D.
• Stress and hormones: Cortisol and Total Testosterone.
• Inflammation and blood count: hs-CRP and a Complete Blood Count.

The results show how the blood values associated with sleep quality compare to the reference ranges. Chronic sleep deprivation can become visible in a higher HOMA-IR, an elevated CRP or a shifted cortisol.

Sleep and focus are closely linked: our InsideTracker Cognition blood test measures the blood values behind your focus. The full InsideTracker blood test measures 36 blood values in one go. Keep in mind that a single value is not a diagnosis.

For this blood test, a staff member draws a small tube of blood at a certified location. You can choose from 700+ collection sites, so there is almost always a location near you.

You only need your appointment confirmation and a valid ID. The draw usually takes just a few minutes.

Some people choose to measure these values:

• When they sleep poorly for a long time and want to see whether it shows in their blood
• When they work rotating shifts and want to follow their values
• When they want to check whether their magnesium and vitamin D are on track
• When they want to objectively follow the effect of better sleep habits

What the results mean depends on your personal situation. This panel does not measure your sleep itself but the blood values associated with it; the pattern across several values is more informative than one isolated result.

Always discuss any deviating values with your GP, so you know what the results may mean for you personally.

Fasting is required for this panel: your glucose and insulin are only interpretable when fasted, and HOMA-IR is calculated from them. Do not eat for 10 to 12 hours before the draw and drink only water.

Plan a morning draw, which also makes your cortisol most informative. If in doubt, discuss your situation with your GP.

You receive your results digitally in your account, usually within a few working days. For each value, you can see whether it falls within the reference range.

Every blood test result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
