Testing for vitamin B12 deficiency at home is relatively simple and can typically be done without the help of a doctor. One of the main ways to test for a B12 deficiency is to use an over-the-counter B12 test kit.
This test utilizes a liquid solution of copper sulfate and dexpan graphanate, which reacts with B12 to create a specific color change visible on a testing strip. By comparing the color on the strip with the included color chart, users can determine their if their vitamin B12 levels are in the healthy range or if they may need medical intervention to address a deficiency.
However, this type of test doesn’t always provide a complete or accurate assessment, and users may want to consider consulting a medical professional to get a formal diagnosis. Blood tests are often used to formally diagnose B12 deficiencies, and they are widely considered to be the most effective way to accurately assess and monitor B12 levels.
Blood tests used to measure B12 concentration typically require a small amount of blood drawn from a vein in the arm. Results from these tests will generally be more accurate and comprehensive than an over-the-counter B12 test, and they can be used to more effectively diagnose and address B12 deficiencies.

How do I know if I have B12 deficiency?
The most common signs include fatigue, weakness, constipation, loss of appetite, weight loss, and tingling sensations in the hands and feet. Other symptoms can include pale skin, jaundice, confusion, depression, a sore tongue, and anemia.
If you have multiple symptoms that suggest a B12 deficiency, it is important to talk to your doctor as soon as possible.
Your doctor may recommend that you get a blood test to measure your B12 levels. Knowing your B12 levels can help your doctor determine if you need to take supplements or get a B12 injection. In some cases, a deficiency in B12 can be corrected through dietary changes, such as increasing your intake of foods that are rich in B12 like nuts, fish, poultry, eggs, and dairy products.
If you have a B12 deficiency, it is important that you get the treatment you need in order to ensure your overall health and wellbeing.
What happens if vitamin B12 is low in adults?
If an adult has a vitamin B12 deficiency, it can lead to a variety of health problems. Low levels of vitamin B12 can cause fatigue, anemia, and nerve damage. Neurological symptoms can include numbness and tingling sensations, difficulty walking, depression, and memory loss.
Some people may also experience extreme exhaustion, vision problems, or a sore tongue or mouth.
A practitioner can diagnose vitamin B12 deficiency by performing a simple blood test. If a deficiency is found, they may recommend that the patient makes dietary changes to increase their B12 intake or take vitamin B12 supplements.
In some cases, people may need B12 shots. A diet rich in vitamin B12-containing foods, such as beef, eggs, dairy, fish, and fortified grains, will help keep levels of this essential vitamin at optimal levels.
How can I raise my B12 levels fast?
There are several steps you can take to raise your B12 levels as quickly as possible.
First, it’s important to identify any potential causes of a low B12 level. These include dietary deficiencies, medication interactions, malabsorption, and certain medical conditions such as pernicious anemia, Crohn’s disease, and celiac disease.
If you suspect any of these may be contributing to your low B12 levels, it’s important to consult your doctor to determine the proper course of action.
In addition, there are several dietary and lifestyle changes you can make to help increase your B12 levels. Increasing your dietary intake of naturally occurring B12 foods is an effective way to increase your B12 levels.
Foods rich in B12 include seafood, liver, eggs, and dairy products. Additionally, supplementation with a B12 vitamin is another beneficial way to increase your B12 levels. Because vitamin B12 is not absorbed well when taken orally, it is best to get B12 from injections.
Another option is to take a combination of B12 and folic acid, which helps the body absorb the B12 better.
Last but not least, it is essential to pay attention to your overall health as a whole. Eating a balanced diet, getting regular exercise, and reducing stress levels can all play a role in improving your B12 levels.
It’s also important to avoid alcohol and smoking, as these can interfere with the body’s ability to absorb B12.
By following these steps, you can help to increase your B12 levels as quickly as possible. However, it is important to note that the time to increase your B12 levels will depend on the severity of the deficiency and other factors.
Therefore, it’s always best to consult with your doctor before taking any steps to increase your B12 levels.
What is the most accurate test for B12 deficiency?
The most accurate test for B12 deficiency is a blood serum test measuring vitamin B12 levels. Vitamin B12, or cobalamin, is an essential nutrient required for proper red blood cell formation, hormone production, and neurological function.
A vitamin B12 deficiency can be caused by eating a diet lacking in B12-rich foods, absorption issues, certain medical conditions, or medication.
A serum test measures the concentration of vitamin B12 in the blood, which is the most accurate way to determine B12 deficiency. In order to ensure an accurate result, the test should be taken first thing in the morning after a fast of 8-12 hours.
The test results can then be compared to the reference range provided by the laboratory to determine if the B12 levels fall within a normal range or indicate deficiency.
Additional tests, like a red blood cell count or methylmalonate test, can be useful for determining the cause of the deficiency, but the serum test should be done first in order to accurately set a baseline for B12 levels.
If a B12 deficiency is suspected or confirmed, a healthcare practitioner can provide a tailored treatment plan for addressing the underlying causes, as well as prescribe B12 supplements as needed.
Why am I suddenly B12 deficiency?
There are numerous potential causes of sudden B12 deficiency, the most common being a lack of dietary intake of vitamin B12-containing foods. This can result from following a vegan or vegetarian diet, which eliminates all animal sources of B12.
Other dietary concerns that can contribute to B12 deficiency include a decreased absorption of B12 due to gastrointestinal issues, such as Crohn’s disease, Helicobacter pylori infection, or celiac disease.
Certain medications can also contribute to decreased absorption of B12, including metformin, proton-pump inhibitors, and H2 blockers. Long-term use of these medications can lead to an increased risk of deficiency.
Additionally, pernicious anemia is an autoimmune disorder in which the immune system attacks the gut, impairing its ability to absorb B12. This type of deficiency is particularly common among older adults and can be a sign of a more serious underlying health condition.
If you believe you may be suddenly B12 deficient, it is best to consult a healthcare professional for testing and to rule out any serious underlying medical condition. Once the cause is determined, your doctor can create a treatment plan that best fits your needs.
When should I check my B12 levels?
It is recommended that everyone should check their B12 levels at least once a year. However, those at a higher risk of deficiencies may need to check their levels more frequently. People at a higher risk include those that are older than 50, are taking certain medications, have had a gastric bypass procedure, have gastrointestinal problems, or follow a vegan diet.
Those with a family history of anemia, are pregnant or recently delivered a baby, have had recent surgery, or have persistent fatigue should also consider speaking to their doctor about checking their levels more regularly.
Does a routine blood test check for B12 deficiency?
Yes, a routine blood test can check for a B12 deficiency. Generally, a complete blood count (CBC) or a comprehensive metabolic panel (CMP) will include a measure of B12 levels, however, some tests may not test for it specifically.
A CBC measures different parts of your blood, including the red and white blood cells and platelets, hemoglobin, hematocrit, mean corpuscular volume (MCV), among other things. CMP measures your blood glucose levels and electrolytes, as well as liver and kidney functioning.
If your healthcare provider suspects a B12 deficiency, they may order a more specific test, such as a vitamin B12 test. Low B12 levels in the blood can indicate a B12 deficiency, and if the deficiency is severe, symptoms may include fatigue, shortness of breath, pale skin, poor appetite, and tingling or numbness in the hands and feet.
Can you take too much vitamin B12?
Yes, it is possible to take too much vitamin B12. Although vitamin B12 is a water-soluble vitamin—so the body will excrete any excess in the urine—it is possible to take in more than the recommended daily allowance (RDA).
Also, since B12 has a low toxicity profile, the health effects of taking too much vitamin B12 may not be immediately visible. It’s possible to experience symptoms a few days later such as headaches, anxiety, and insomnia.
In very rare cases, people on high-dose vitamin B12 supplements may develop permanent nerve damage, which can cause tingling, numbness, and loss of balance.
Therefore, it is important to talk to your doctor before taking any vitamin B12 supplements, and to make sure you are taking the appropriate amount, as determined by your doctor.
Can you have normal blood count and B12 deficiency?
Yes, it is possible to have a normal blood count (which is determined through a complete blood count or CBC test) and still have a B12 deficiency. This can because the CBC does not specifically measure vitamin B12 levels, but instead looks at the overall health of your red blood cells.
B12 deficiency may still exist even if normal blood counts are observed, as lower B12 levels can eventually result in changes to red blood cell synthesis and its associated markers. Healthcare professionals can run additional tests, such as measuring serum levels of B12, or Methylmalonic Acid (MMA), to determine if B12 deficiency is present.
If a B12 deficiency is found, Vitamin B12 supplementation, dietary modification or other therapies may be necessary.
What does CBC look like with B12 deficiency?
A CBC with B12 deficiency can vary depending on the severity of the deficiency, but typically a patient will have decreased hemoglobin and red blood cell count, as well as elevated white blood cell and platelet count.
The MCV (mean corpuscular volume) of red blood cells may be lower than normal and the red blood cells may appear smaller. Chronic vitamin B12 deficiency can also cause a type of anemia known as “megaloblastic anemia”, which is characterized by large, immature red blood cells (macrocytosis).
Additionally, there may be neutrophilia (increased number of neutrophils), leukocytosis (increased white blood cell count), and increased platelet count.
What does low B12 feel like?
Low B12 can cause a wide range of unique symptoms depending on the individual and the severity of the deficiency. Some common symptoms include fatigue, depression, brain fog, poor memory, pale skin, weakness, shortness of breath, prickling sensations, soreness of the tongue, mouth ulcers, anemia, and constipation.
As B12 is essential to a healthy nervous system, a deficiency can also cause tingling, balance problems, and poor reflexes. Deficiencies can have serious long-term health effects, so it is important to get screened as soon as you start experiencing symptoms.
If your B12 levels are low, treatment can involve taking supplements, dietary changes, and intramuscular injections of B12.
How much vitamin B12 does it take to fix a deficiency?
The amount of vitamin B12 that is necessary to treat a deficiency can vary greatly depending on the severity of the deficiency and the individual’s needs. Generally speaking, between 1000-2000mcg of B12 per day is considered therapeutic and should be taken in divided doses throughout the day.
A higher dose may be necessary to help correct severe deficiencies and may need to be taken with folic acid or other B vitamins and monitored by a doctor. Individuals with a mild B12 deficiency may find that dietary sources of B12 such as fish, eggs and fortified foods are sufficient to treat their deficiency, but those with a more significant deficiency may need an injection of B12, especially if oral supplementation isn’t enough.
A doctor can evaluate your levels and determine the exact dosage that is necessary to correct your deficiency.
What causes B12 to drop low?
Low levels of vitamin B12 (also known as cobalamin) can occur for a variety of reasons. One of the most common is insufficient dietary intake. Vitamin B12 is found only in animal-based foods like fish, poultry, eggs, and dairy products, which may be lacking in vegetarian and vegan diets.
Other conditions that may lead to low levels of B12 include pernicious anemia, Crohn’s disease, celiac disease, and intestinal surgery, as these conditions interfere with the body’s ability to absorb B12.
Bacterial overgrowth, certain medications, and certain genetic conditions may also contribute to low B12 levels.
What diseases can cause low B12?
Low B12 can be caused by any number of diseases that interfere with the body’s ability to absorb or use the vitamin. The most common is pernicious anemia, an autoimmune condition that makes it difficult for the body to absorb B12 from food.
Some other conditions that may cause low B12 include gastro-intestinal issues such as celiac disease, Crohn’s disease, and some food intolerances, as well as gastric bypass surgery. Other medical causes of B12 deficiency include chronic kidney disease, liver disease, chronic alkoholism, type 2 diabetes, and some types of cancer, such as multiple myeloma or leukemia.
Certain medications and treatments such as long-term use of proton pump inhibitors and metformin can also cause a B12 deficiency. A vitamin B12 deficiency can also be caused by an inadequate diet, either as a result of inadequate intake or an inadequate absorption of the vitamin.
Vegetarians and vegans are particularly at risk for B12 deficiency due to their reduced intake of animal-based foods.
