Blood Test For Vitamin B12

Treating Vitamin B12 Deficiency Anaemia

B12 blood test and Vitamin D and Folate – What does it mean?

Vitamin B12 deficiency anaemia is usually treated with injections of vitamin B12, in a form called hydroxocobalamin.

At first, you’ll have these injections every other day for two weeks, or until your symptoms have stopped improving. Your GP or nurse will give the injections.

After this initial period, your treatment will depend on whether the cause of your vitamin B12 deficiency is related to your diet. The most common cause of vitamin B12 deficiency in the UK is pernicious anaemia, which isn’t related to your diet.

Most people need to take folic acid tablets for about four months. However, if the underlying cause of your folate deficiency anaemia continues, you may have to take folic acid tablets for longer possibly for life.

Before you start taking folic acid, your GP will check your vitamin B12 levels to make sure they’re normal. This is because folic acid treatment can sometimes improve your symptoms so much that it masks an underlying vitamin B12 deficiency.

If a vitamin B12 deficiency isn’t detected and treated, it could affect your nervous system.

Functional Vitamin B12 Deficiency

Functional vitamin B12 deficiency occurs when people have vitamin B12 deficiency symptoms yet appear to have normal vitamin B12 levels in their blood.

This can happen if theres a problem with proteins that help transport vitamin B12 between bodily cells, which results in neurological complications involving the spinal cord.

About Vitamin B12 Or Folate Deficiency Anaemia

Vitamin B12 or B9 deficiency anaemia occurs when a lack of vitamin B12 or folate causes the body to produce abnormally large red blood cells that can’t function properly.

Red blood cells carry oxygen around the body using a substance called haemoglobin.

Anaemia is the general term for having either fewer red blood cells than normal or having an abnormally low amount of haemoglobin in each red blood cell.

There are several different types of anaemia, and each one has a different cause. For example, iron deficiency anaemia, which occurs when the body doesn’t contain enough iron.

Ways To Increase Vitamin B12

The most important thing is to work with your doctor to find out whats causing your low vitamin B12 levels and to treat any underlying conditions.

Discuss the additional lifestyle changes listed below with your doctor. None of these strategies should ever be done in place of what your doctor recommends or prescribes!

1) Get More Vitamin B12 in Your Diet

If your diet is low in vitamin B12, try and boost your dietary B12 intake.

Common sources of B12 include animal products such as red meat, fish, poultry, yogurt, and milk. Vitamin B12 is poorly absorbed from eggs .

A couple of studies suggest that algae may also be a viable source of B12 .

However, keep in mind that vitamin B12 levels are often low due to underlying conditions, such as impaired nutrient absorption due to gut-associated disease. In these cases, a simple dietary change wont help increase B12 levels.

2) Avoid Alcohol

Alcohol consumption can reduce B12. Avoiding it will prevent further decreases in B12 levels .

3) Avoid Smoking

Smoking can also lower B12 levels and should be avoided .

4) Alternative Drugs

Knowing that your drugs likely decrease B12 levels can help if you take action and supplement accordingly. Metformin in diabetics is a good example .

Review your medication with your doctor or another healthcare professional, and discuss alternatives for those that are decreasing your B12 levels.

5) Supplements

Natural or biologically active forms are a better option than synthetic cyanocobalamin.

What Happens During A Vitamin B Test

Vitamin B levels may be checked in blood or urine.

During a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

Vitamin B urine testing may be ordered as a 24-hour urine sample test or a random urine test.

For a 24-hour urine sample test, you’ll need to collect all urine passed in a 24-hour period. This is called a 24-hour urine sample test. Your health care provider or a laboratory professional will give a container to collect your urine and instructions on how to collect and store your samples. A 24-hour urine sample test generally includes the following steps:

  • Empty your bladder in the morning and flush that urine away. Record the time.
  • For the next 24 hours, save all your urine passed in the container provided.
  • Store your urine container in the refrigerator or a cooler with ice.
  • Return the sample container to your health provider’s office or the laboratory as instructed.

For a random urine test, your sample of urine may be collected any time of the day.

It is important for women who are pregnant to increase their consumption of these vitamins. Folate in particular is critical to the development of the spinal cord and brain stem. There is also an increased need when there is a Stage 4 cancer or certain chronic anemias affecting a persons health as well.

Why Normal Levels Can Differ Across Different Labs

Each laboratory must establish its own normal ranges for vitamin B12 in the blood. These ranges depend on the makeup of the local population, the technologies used and the accuracy of the measurement. There may be also slight differences in the normal levels, according to age, gender, race or ethnic origin, geographic region, diet, type of sample and other relevant status.

Your doctor will study the results along with your medical record, screenings, physical condition, symptoms and any other relevant information about your situation.

What Causes Vitamin B12 Deficiency Anemia

Vitamin B12 deficiency anemia is more common in people whose families come from northern Europe. It is caused by one of the following:

  • Lack of intrinsic factor. Intrinsic factor is a protein made in the stomach. It is needed to absorb vitamin B12. This type of B12 deficiency anemia is called pernicious anemia.
  • Surgery that removes or bypasses the end of the small intestine. This part of the small intestine is where vitamin B12 is absorbed.

The inability to make intrinsic factor may be caused by several things, such as:

  • Chronic gastritis
  • Surgery to remove all or part of the stomach
  • An autoimmune condition, where the body attacks its own tissues

Other types of megaloblastic anemia may be linked with type 1 diabetes, thyroid disease, and a family history of the disease.
