Are you looking to learn how to test for vitamin deficiency? Let me shine some light on this for you.

Hi, I am Alane, a holistic nutritionist with 30+ years of experience in holistic health. I started my career decades ago working in a busy vitamin shop in NJ.

I loved working there and learning how each specific vitamin deficiency can cause a particular symptom or health challenge for our customers. People would come in daily and buy lots of vitamins, hoping to feel better. I started to take vitamins and see how they made me feel. I noticed that I was more alert and energetic and not getting as sick as I always was.

Over the months, one thing started to trouble me with the customers. They were spending so much on vitamins; some said they felt better, and others did not. Call me a little on the OCD side and a deep thinker – but this nutritionist wanted to figure out what each customer needed, so they only bought the vitamins their body needed. And I was also buying vitamins and needed to figure out what I needed. I needed to test myself for vitamin and mineral deficiencies, so I only spent money on what my body needed. So I started to research how to test for vitamin deficiency accurately. 

I kept coming back to one test and one lab. Sure there are others, but over the last 30 years, I have not seen as much success with any other test. This one makes sense. 

Let me explain

I can run vitamin deficiency testing at my clinic whenever I want. Some methods include saliva, finger prick, blood draw, and hair sample. So I will only use what works. The only way this nutritionist will teach how to test for vitamin deficiency is in whole blood with a proper blood draw. A finger prick is not stable enough during the stick or transport of the sample. It is unstable and uses unreliable technology. The current technologies still have issues that can cause failures.

A venous blood draw will give you the most accurate results as the sample is stable. Sure, you will have to go to a lab facility or have someone come to your home, but that is better than spending money on a sample you don’t know is accurate. 

The lab I use for the blood test for vitamin deficiency is CLIA certified and a trusted source. 

The type of blood test I use for vitamin and mineral deficiency is called a micronutrient test. It is highly comprehensive and measures your functional vitamin deficiencies at the cellular level. This point is vital to understand. It is an assessment of how well the body utilizes 31 vitamins, minerals, amino/fatty acids, antioxidants, and metabolites while conveying the body’s need for these micronutrients that enable the body to produce enzymes, hormones, and other substances essential for proper growth, development, and good health.

My lab tests your WBC’s, where the functionality of your vitamins takes place, and where the nutrients do their job, so you feel healthy and well. 

Other tests are static serum tests. Serum vitamin deficiency tests only assess the concentration of nutrients outside the cell.

My Micronutrient test is a long-term assessment (4-6 months) that addresses the functional impact (performance) of your vitamins, minerals, and antioxidants—what matters. 

So if you want to know what vitamins, minerals, antioxidants, and immune support your body needs, don’t guess, and only look at the intra-cellular level your actual vitamin needs. 

True story: I ran my first test on myself and was surprised, but not really. I was getting sick a lot and was kind of run down. An interesting fact was my vitamin test came back with deficient antioxidant levels. So I spent one year supporting my immune system with the exact antioxidants the test results said to use, retested one year later, and not only was I feeling a whole bunch healthier, but my antioxidant levels had improved so I could reduce them.
