At a glance
Keto vitamin deficiency testing screens the nutrient and iron markers that restrictive low-carb, high-fat diets can leave short, nutrients that support nerve, muscle, and immune function. It is designed for people following keto or another restrictive eating pattern who want lab data on whether their food choices are meeting their nutritional needs. Options range from a focused 7-test High Fat Diet Vitamin Deficiency panel to comprehensive keto panels covering up to 112 biomarkers.
Best suited for
- People on keto or other restrictive diets who want to screen for nutrient shortfalls
- Low-carb eaters experiencing low energy who want lab data to review with their doctor
- Anyone tracking iron storage (ferritin) and inflammation markers alongside a major diet change
- Long-term keto followers who have never had a nutrient-focused lab workup

Key biomarker ranges
Commonly used adult reference ranges for markers this panel measures, labs vary, so always interpret results against your lab's stated ranges and with your doctor.
Commonly used cutoffs: below 20 ng/mL deficient, 20–30 insufficient, 30–60 a frequently cited target band; season and supplementation move levels substantially.
| Zone | Range |
|---|---|
| Deficient | 0–20 ng/mL |
| Insufficient | 20–30 ng/mL |
| Sufficient | 30–60 ng/mL |
| High | 60–100 ng/mL |
Commonly used reference ranges differ by sex, roughly 30–200 ng/mL is typical, with men’s upper bounds higher; inflammation can raise ferritin and mask low iron.
| Zone | Range |
|---|---|
| Low | 0–30 ng/mL |
| Typical range | 30–200 ng/mL |
| Elevated | 200–400 ng/mL |
Commonly used cutoffs: under 1 mg/L low, 1–3 mg/L average, over 3 mg/L high; acute illness or injury can spike results, so retesting confirms a trend.
| Zone | Range |
|---|---|
| Low | 0–1 mg/L |
| Average | 1–3 mg/L |
| High | 3–10 mg/L |
The importance of testing
Any diet that removes whole food groups can quietly under-supply specific nutrients, and keto removes more than most. These panels screen nutrient levels that support nerve, muscle, and immune function, so you can see on paper whether a restrictive eating pattern is keeping up with your body's needs rather than relying on how you feel day to day.
Iron and inflammation markers add important context. Ferritin reflects iron storage, and inflammation markers can shift with significant dietary changes, together they help you and your doctor interpret whether a trend is diet-related or worth a closer look. A complete blood count on the broader panels provides an additional check on blood health markers that diet changes can affect.
The focused High Fat Diet (Ex. Ketogenic) Vitamin Deficiency Test Panel covers 7 targeted tests for adults 18 and older, while the full keto panels layer nutrient screening on top of lipid, glucose, insulin, thyroid, liver, and kidney markers. Test before or early in your diet, retest as your eating pattern settles, and bring any flagged results to your doctor to discuss whether food adjustments or supplementation deserve a conversation.

What does keto vitamin deficiency testing check?
It screens nutrient levels that restrictive diets like keto can under-supply, nutrients that support nerve, muscle, and immune function, along with iron storage (ferritin) and inflammation markers on the broader panels. The focused High Fat Diet Vitamin Deficiency Test Panel includes 7 targeted tests, while comprehensive keto panels cover up to 112 biomarkers.
Why would a keto diet cause nutrient shortfalls?
Because keto restricts entire food groups, it can reduce your intake of nutrients those foods normally supply, which is why nutrient screening is commonly paired with restrictive diets. Lab testing replaces guesswork with measured levels you can track over time and discuss with your doctor.
Can I order a keto vitamin deficiency test without a doctor's visit?
Yes, the panels are ordered directly online through the partner site with no doctor's visit or referral required, and the vitamin deficiency panel is available to adults 18 and older. You complete sample collection at a local lab and receive results to review with your own doctor.
Should I choose the focused vitamin panel or a full keto panel?
Choose the 7-test High Fat Diet Vitamin Deficiency panel if your only question is nutrient status, and a broader keto panel (10 to 20 tests) if you also want lipid, glucose, insulin, thyroid, liver, and kidney markers in the same draw. A comprehensive baseline gives you more trends to compare at your next retest.
Is this testing available in every US state?
No, direct-to-consumer lab testing is restricted or prohibited in New York, New Jersey, and Rhode Island, so residents of those states may be blocked at the partner's checkout. Elsewhere, availability depends on having a partner lab location nearby.
