How to prepare
Before you collect your samples, here's what to keep in mind:
Fasting: An overnight fast of 8–12 hours is recommended, as some components (such as lipid and glucose markers) are most accurate on a fasting sample. Water is fine during the fast.
Timing: Collect your blood spot and urine samples first thing in the morning, ideally between 7–9 am. Hormone levels (including cortisol and testosterone) fluctuate throughout the day, and morning collection gives the most consistent results.
Supplements: Stop taking supplements 48 hours before collection, unless you're specifically monitoring supplementation levels (in which case, continue as normal and note it on your requisition form). Fat-soluble supplements (vitamins A, D, E, K) and fish oil may need a 72-hour hold — check the instructions in your kit.
Medications: Some medications can affect results. If you take prescription medication, check with your healthcare provider about whether to adjust timing around your collection.
Blood spot collection: Warm your hands for 3–5 minutes before starting. Use the lancet provided to prick the side of your ring or middle finger. Let large drops fall onto the collection card circles — don't smear. Allow the card to air-dry flat for at least 30 minutes before packaging.
Urine collection: Collect a first-morning midstream urine sample in the container provided. Avoid the first and last portions of the stream. Refrigerate the sample immediately and package it with your blood spot card on the same day.
Returning your kit: Once everything is collected, dried, and packaged, place all samples in the prepaid return satchel and post on the same day or next business day. Don't leave the satchel in a hot letterbox or car.
After the test
Once you have your results, the most valuable thing you can do is share them with a qualified healthcare provider or functional medicine practitioner. They can interpret the findings alongside your health history, symptoms, and goals — and help you put together a plan if anything needs attention.
Many people use NutriSTAT as a detailed baseline, then retest every 6–12 months to track changes over time.
Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.
Understanding results
Your report covers every tested category with clear reference ranges and context on what each result may mean for your health. You'll see where your markers sit across metabolic function, thyroid status, cardiovascular risk factors, hormones, minerals, toxic metals, fatty acids, amino acids, and organic acids.
The report is designed to be shared with your healthcare provider, who can interpret the results in the context of your full health picture and advise on any next steps. Some results may highlight areas worth exploring further — your practitioner can help you decide what matters most.
Results are typically available within 21 business days of the laboratory receiving your samples.
