Vitamin Deficiency Test
FAQ
-
What are vitamins, and how do they affect the body?
Vitamins are organic compounds your body needs to grow and function properly but, sometimes, can't produce on its own. They are found in different food groups in varying amounts. When you ingest them, vitamins regulate chemical processes throughout your body, enabling it to perform essential functions. A deficiency in any vitamin, if left untreated, can lead to serious health problems like:
- Blindness
- Anemia
- Skin diseases
- Cardiovascular disease
Therefore, testing for vitamin deficiencies is important to recognize the need for a specific treatment and improvement in your diet to ensure good health.
-
How to test for vitamin levels and deficiencies?

Vitamin deficiency does not let your body function.
Most vitamins need to come from food because your body either doesn't produce them (or produces very little).
Vitamin deficiency test comes in two types:
- Fat-soluble - Vitamins A, D, E and K
- Water-soluble - B Group Vitamins (B1, B2, B3, B5, B6, B7, B12) and Vitamin C
The main difference is that you can store fat-soluble vitamins. Sometimes to a toxic level. But you can't store water soluble vitamins (with the exception of Vitamin B12).
Either way your body is always using them up to maintain your health. So you have to constantly replenish them or you will run out.
You could have low levels for a variety of reasons.
It could be because of your diet.
Many Vegans and some vegetarians will find it difficult to get enough B Complex vitamins. Especially vitamin B12 as plants do not produce it.
But it could also be a digestive issue, like a lack of key enzymes to extract the vitamins from the foods you do eat.
That's why periodic vitamin deficiency testing should be a part of any self care protocol.
And while you're looking at a vitamin test, it's a good idea to keep an eye on your minerals and micronutrients too for a complete nutrition deficiency test.
- Iron
- Magnesium
- Phosphorus
- Zinc
- Chloride
- Calcium
- Potassium
- Sodium

What is a vitamin test?
A vitamin test is used to identify vitamin and nutrient deficiencies in a patient, which could be causing or contributing to chronic health issues or conditions. Nutritional imbalances can lead to conditions such as hair loss, fragile nails, white nail spots, insomnia, rashes, feeling unwell and other health problems. Vitamin deficiencies can also lead to more serious health conditions. These can have a drastic effect on your physical and mental well-being. That’s why taking a vitamin test regularly, either as part of a yearly checkup, or for particular symptoms is so important.
Who may need a vitamin test?
Your physician or nutritionist may order a vitamin test as part of your yearly checkup. Or you could do it yourself. If you feel any of the symptoms, like hair loss, fragile nails, white nail spots, insomnia, rashes, feeling unwell, depression or bleeding gums, then a vitamin test is often the first step to pinpointing the cause. A vitamin test is also an essential tool for anyone undergoing a big change affecting your digestion. For example surgeries on the stomach or digestive system, like gastric bypass. Or dietary changes can all affect your vitamin levels and should be monitored.
What should I expect from my vitamin test?
A vitamin test is a simple procedure. A small sample of your blood will be drawn and sent to a lab for testing. Then in a few days you will receive your results. One thing to note: our labs will include a reference range for each vitamin. Meaning a value for high and low level so that you can easily read your test results on your own. However your doctor or nutritionist might have another range that they use for their patients. Either is fine, but if you’re following a specific treatment plan then use the range provided in that plan.
