What this test tells you:

Vitamin D Home Test Biomarker Results

Our Vitamin D Test measures the vitamin D levels (total, 25-hydroxy D2 and D3) in your blood by nanograms (ng) per milliliter (mL). Results range from < 20 ng/mL (deficient, or very low) to > 100 ng/mL (potential toxicity, or very high).

Vitamin D Deficiency vs. Insufficiency:

Healthy vitamin D levels should sit between 30 and 100 ng/mL. However, those with a vitamin D deficiency (approximately 1 billion people worldwide) have levels at or below 20 ng/mL. Though low levels of vitamin D are most often associated with a deficiency, approximately half of the global population has insufficient vitamin D levels, or those between 20 and 30 ng/mL. Though not as serious, vitamin D insufficiency can lead to a deficiency and should be addressed similarly.

Vitamin D plays a key role in regulating your bone metabolism, immune system and inflammatory responses. Lower levels of vitamin D have been associated with various inflammatory disorders, poor bone mineralization and even increased risk of certain cancers.

Considered a global health crisis, it’s estimated that vitamin D deficiency affects about 1 billion people across the globe. Though sunshine and supplements are two common methods for increasing vitamin D levels, you can also get your recommended dose of vitamin D through fortified foods and fatty fish, like salmon and mackerel.

Research has shown that vitamin D deficiencies are often correlated with certain medical conditions, including:

  • Osteoporosis (and other forms of poor bone mineralization
  • Cardiovascular disease
  • Diabetes
  • Rheumatoid arthritis
  • Multiple sclerosis

Medications such as cholestyramine, colestipol, orlistat and mineral oil can also inhibit vitamin D-absorption so it’s important to first discuss solutions with a healthcare practitioner if your vitamin D levels are low.

Who is Notch for?
Notch is for anyone over the age of 18 who is looking to complete a lab test from the comfort of their own home. Our health tests cater to those who are looking to pinpoint food sensitivities, vitamin deficiencies, airborne/environmental sensitivities and more.

Do I need a prescription to use Notch?
No, you do not need a prescription. Notch works with a physician network to authorize test requisitions in each state that we offer test kits.

Where do you ship to?
We currently ship to most U.S. addresses and U.S. territories, excluding New York State, New Jersey and Rhode Island. We do not ship to PO Boxes/APO/FPO addresses.

Is my information safe?
We take your privacy and the security of your information very seriously. We’ve designed the Notch platform to be HIPAA-compliant and have implemented strict security protocols to protect your information. Please read our Privacy Policy for more details.

Are Notch health tests the same tests you would take in a doctor’s office?
Notch health tests are the same tests as you would take in a doctor's office. Samples are sent to our CLIA-certified lab and analyzed by qualified laboratory technicians. The only difference is the method in which we collect your blood. We collect blood with a capillary blood sample (finger prick) instead of a venous blood sample (taken from the vein).

Is this replacement for visiting a doctor?
If and when possible, we encourage everyone to use their own doctor and health insurance for health tests. Home health testing is often more convenient and flexible than traditional health testing. However, we are not a replacement for visiting a doctor and do not diagnose, prescribe, treat or provide personal medical advice.
