    What is a Vitamin B12 Test?

    A Vitamin B12 test determines the concentration of Vitamin B12 (cobalamin) in the blood, an essential nutrient required for maintaining healthy nerve cells and blood cells. In addition to this, Vitamin B12 also aids in the synthesis of deoxyribonucleic acid (DNA) which is the genetic material present in every cell of the body. The human body has to get its supply of Vitamin B12 from foods like meat, eggs, and dairy because it is unable to generate it on its own.

    In India, approximately 47% of people suffer from Vitamin B12 deficiency, which can lead to macrocytic anaemia. This can cause neuropathy, resulting in tingling or numbness in the hands and feet. Therefore, getting a Vitamin B12 test in Noida is crucial to guarantee general health and avoid any potential issues.

    Vitamin B12 Parameters

    To effectively use Vitamin B12 from consumed foods, the body must undergo two processes. First, hydrochloric acid in the stomach breaks down the Vitamin B12-containing foods. Then, Vitamin B12 binds with the intrinsic factor, a protein produced by the stomach. This complex is absorbed by the digestive system. Vitamin B12 is crucial for red blood cell production, cell, and tissue repair, and maintaining the myelin sheath, which insulates nerves and ensures normal nerve function.

    The Vitamin B12 test contains only one parameter: the concentration of Vitamin B12 in serum or plasma (the liquid component of blood). Thus, it is known as the serum Vitamin B12 blood test.

    Vitamin B12 Test Preparation

    Key aspects of the Vitamin B12 blood test are:


    Fasting is not necessary before taking the Vitamin B12 test.

    Best Time to Get Tested

    A Vitamin B12 test can be performed at any time of the day.

    Who Should Get a Vitamin B12 Test

    Individuals of any age can be affected by Vitamin B12 deficiency. Those experiencing symptoms such as weakness, nausea, or irritability should undergo the test.

    Cautions Before Taking Vitamin B12 Test

    Some medications, including proton pump inhibitors, may affect the test results. Ensure your doctor is aware of any medications you are taking before the test.

    Why Take a Vitamin B12 Test?

    If your full blood count indicates low haemoglobin, large red blood cells, or unusual white blood cells, a Vitamin B12 test may be recommended by your doctor. Other reasons to undergo this test include symptoms such as:

    • Tingling or numbness in the hands/feet

    • Nausea

    • Vomiting

    • Reduced appetite

    • Extreme fatigue or weakness

    • Yellowish skin

    • Diarrhoea

    • Weight loss

    • Soreness in the mouth or tongue

    • Vision problems

    • Impaired walking or speech

    • Irritability

    • Depressed mood

    • Memory issues or confusion

    • Mood and behaviour changes

    You might also require a Vitamin B12 test if:

    • You consume excessive alcohol, which can damage the digestive system and lower B12 levels.

    • You are taking medications that reduce B12 levels (e.g., medications for diabetes or peptic ulcers).

    • You have Sjögren's syndrome, significantly increasing the risk of B12 deficiency.

    • You are over 70, as older adults are at a higher risk of B12 deficiency due to reduced nutrient absorption.

    • You have digestive disorders such as celiac disease or Crohn's disease, which hinder B12 absorption.

    • You follow a plant-based diet, as B12 is naturally present in animal products.

    • You are being treated for malnutrition or a B12 deficiency, as this test helps assess treatment progress.

    • You are pregnant, since pregnant women require more B12 to support their baby's growth.

    Additionally, doctors might recommend checking homocysteine levels, which can help diagnose a B12 deficiency and identify the cause. This helps in facilitating proper treatment.

    Vitamin B12 Test Results & Interpretation

    Normal Vitamin B12 Range

    The normal range for Vitamin B12 is 239-931 pg/mL

    Understanding Test Results

    Low Levels

    A deficiency in Vitamin B12 may be indicated by levels below the normal range, caused by:

    • Absence of intrinsic factor or presence of intrinsic antibodies (typical in pernicious anaemia)

    • Insufficient dietary intake, especially in vegetarians

    • Fish tapeworm infection

    • Elevated homocysteine levels

    • Gastrointestinal issues like atrophic gastritis

    • Hereditary conditions, such as transcobalamin II deficiency

    • Absorption problems due to conditions like Crohn's disease, celiac disease, pancreatitis, or small bowel resection

    • Surgical interventions, such as weight loss surgeries

    Higher demands for Vitamin B12 during the final trimester of pregnancy can also lead to lower levels. Since vitamin B12 and folate are both required for cell function, your doctor may recommend that you test your folate levels at the same time.

    High Levels

    While elevated Vitamin B12 levels are uncommon due to the body's ability to excrete excess amounts via urine, certain conditions can cause higher levels. These conditions include:

    • Cirrhosis

    • Chronic kidney disease

    • Congestive heart failure

    • Protein malnutrition

    • Polycythaemia vera

    • Metastatic liver disease

    • Acute hepatitis

    • Drug-induced cholestasis

    • Myelogenous or promyelocytic leukaemia

    • Hepatocellular carcinoma

    If your Vitamin B12 test shows a deviation from the normal range, consult your doctor for further guidance and interpretation.
