Vitamin B12 is mostly found in dairy and animal products such as eggs, milk, seafood, and meats. People with vegetarian diets are prone to having a deficiency of vitamin B12. Both high and low levels of vitamin B12 in your body must be regulated with the help of a professional. Therefore, maintaining a balanced diet and getting regular body checkups are of keen importance.
Major signs and symptoms of B12 deficiency depend on the age of a person. A person below 30 years of age might not show symptoms of deficiency. But in many cases, even children require a test to be done. Usually, older people and pregnant women are more prone to this deficiency. In any case, seeking professional advice is of utmost importance.
A person with Vitamin B12 deficiency may show various psychological and physical symptoms such as:
Poor diet intake is the main cause of the deficiency of Vitamin B12. Other than that, some diseases might reduce the levels of Vitamin B12 in the body. One common medical condition anemia causes this deficiency in many patients. Anemia is caused when the stomach is unable to absorb B12 from any kind of diet intake.
Other medical conditions include HIV, Crohn’s, Type 1 diabetes, etc. Additionally, some personal factors such as family history, vegetarian diet, some kind of stomach surgery, medicines, etc.
It’s important to determine a balanced level of Vitamin B12 with regular checkups. It helps to maintain the proper functioning of the body. Some major benefits are as follows:-

It is a simple blood test that is done by drawing blood from an individual and taking the sample to the laboratory for further examination.
The procedure of the test involves a determination of overall levels of Vitamin B12, homocysteine, and holoTC. These levels help in determining the high and low levels of B12. Both low and high levels need to be maintained with proper diagnosis and treatment which the test provides.
It is a common blood test that can be done at any time as per the convenience of the patient. Unlike other blood tests, there is no requirement for fasting before this test. One important thing to consider is that the patient must take proper rest before taking the test.

The normal range of Vitamin B12 is between 211-911 picograms per milliliter. Anything above 900 is considered high level. Whereas, a range below 200 is considered low and will require medical attention. The range might also vary according to different laboratories.
