Functional readout

Spectrox

Total antioxidant function

How well your cells hold up against oxidative stress.

How it works

Your cells grow with and without an oxidizing agent. The score compares how well they hold up.

Why it matters

It shows how all your antioxidants work together. Low glutathione or CoQ10 can pull it down.

In your report: shown as a score.

Functional readout

Immunidex

Immune response score

How strongly your immune cells respond when they are stimulated.

How it works

Your cells get every nutrient and a signal to grow. This batch is also your control.

Why it matters

A broad sign of immune cell function. Nutrient shortfalls and some medicines can lower it.

In your report: shown as a score.

Functional readout

Glucose-Insulin Interaction

Carbohydrate metabolism

How your cells respond to insulin when they use glucose.

How it works

Your cells grow on very little glucose, with and without extra insulin.

Why it matters

If extra insulin helps them grow, they aren't using insulin well. It can't diagnose diabetes.

In your report: flagged if abnormal.

Functional readout

Fructose Sensitivity

Carbohydrate metabolism

How well your cells process fructose, a sugar in fruit and sweeteners.

How it works

Breaking down fructose uses up cell energy. Cells that handle it poorly can run low.

Why it matters

It's about excess fructose from added sugars like corn syrup, not whole fruit.

In your report: flagged if abnormal.

  1. 1Drawing blood

    Two small tubes of blood are drawn and shipped overnight to our lab in Houston.

  2. 2Separating the cells

    We pull out your lymphocytes, a type of white blood cell. These are the cells we test.

  3. 3Setting your baseline

    One batch of your cells gets every nutrient it needs. Its growth is your baseline, called your control.

  4. 4Removing one nutrient

    Each of the other batches is missing a different nutrient, so the cells have to grow using what they already have stored.

  5. 5Comparing growth

    We compare how much each batch grew with your control. Less growth can mean your cells are running low on that nutrient.

Method details for providers

Peripheral blood lymphocytes are isolated and grown in a chemically defined, serum-free and protein-free medium (Shive et al., PNAS 1986). The amount of each nutrient is varied one at a time. The cells are then stimulated with a mitogen, and proliferation is measured by DNA synthesis. Results are reported as a percentage of the patient's own control and compared with nutrient-specific reference ranges. Immunidex is the response of the baseline culture. Every sample is run in triplicate.

What a standard blood test can miss

A nutrient can be in your blood and still not work well inside your cells. A standard serum test only sees what's in your blood. This test shows what your cells do with it.

Standard serum test

How much is in your blood?

  • Measures what's in the liquid part of your blood
  • A snapshot of the day of the draw
  • Can look normal while your cells run low
Vitamin D exampleWithin normal range

SpectraCell Micronutrient Test

How well are your cells using it?

  • Looks inside your own white blood cells
  • Reflects roughly the past 4–⁠6 months
  • Can catch shortfalls a serum test misses
Vitamin D exampleDeficient

The vitamin D results are an illustration, not real patient data.

Your report, nutrient by nutrient

Each result is a percentage of your own control culture, compared with a reference range set for that nutrient.

  • DeficientBelow the reference range
  • BorderlineClose to the low end of the range
  • Within rangeYour cells performed as expected

Spectrox and Immunidex are reported as scores. Glucose-Insulin Interaction and Fructose Sensitivity are flagged if abnormal. Supplemental pages explain each flagged item for you and your provider.

Common questions

Have another question? Call us at (800) 227-5227, Monday to Friday, 8 am to 6 pm Central, or send us a message.

Do I need to stop taking supplements first?

No. Keep taking them as you normally do. The test looks at roughly the past 4–⁠6 months.

Do I need to fast?

No, not for this test. If you're having other tests done at the same time, follow their instructions.

Do any medications affect the test?

After you finish antibiotics or chemotherapy, wait 4–⁠6 weeks before your blood draw. Blood thinners and biotin don't affect the test.

My regular blood test was normal. Can this test still show a deficiency?

Yes. A regular blood test shows how much of a nutrient is in your blood. This test shows how well your cells use it. The two don't always match.

How often should I retest?

Most people test again about six months after starting a new plan, to see what has changed.

Can children be tested?

Yes. Our standard ranges are for ages 12 and up. Younger children can still be tested on the advice of a healthcare provider.

Is this a diabetes test?

No. Glucose-Insulin Interaction shows how your cells respond to sugar and insulin in the lab. It can't diagnose diabetes, and it doesn't replace tests like fasting glucose or HbA1c.

What if my sample can't be tested?

Occasionally a sample can't produce a result because the cells don't grow enough in culture. This is most often due to shipping delays or exposure to extreme temperatures in transit. If this happens, you can contact us about a new blood draw or a refund.
