1. Choose the right tests

Your provider reviews your health history, symptoms and goals, then explains what the nutrient test checks and whether it fits you.

2. Prepare

You are told whether to fast and which supplements or medicines to pause before the draw. Some nutrient results change after recent supplements, so you may be asked to pause them.

3. Blood draw at home

Your provider draws blood at your home, labels it and sends it to the lab. Most draws take only a few minutes.

4. Results visit

When results are back, your provider walks you through each number, what it means and what, if anything, to do next.

the cellular nutrition test safety and monitoring.

How it differs from routine labs

Standard labs check a few nutrients, such as B12, folate or vitamin D. Advanced nutrient tests check many more, but some methods are not used in routine medical care and experts disagree on how useful they are.

Food first

If a result is low, your provider usually suggests food changes first and only the supplements you need, at safe doses.

Too much of a good thing

Some vitamins, such as A, D and iron, can build up and cause harm. Your provider will not suggest high doses without a clear reason.

New York lab rules

Labs that test samples from New York patients must hold a New York State permit for that test. Your provider uses a permitted lab, which is why the exact lab used in Brooklyn may differ from other states.

Diet patterns in Brooklyn

Plant-based diets, long workdays and frequent takeout all shape nutrient intake. Your provider reads your results alongside how you actually eat.

Collected in your home

Your provider collects the sample during your visit, so you skip the trip to a lab. The lab’s handling steps are followed exactly.
