Understand more about Vitamin B12

Vitamin B12 is a part of B complex of vitamins. Vitamin B12 is also called as Cobalamin. It is a water soluble vitamin. Vitamin B12 plays an important role in formation of normal red blood cells, repair of tissues, DNA synthesis and genetic material in cells. It is not produced in the body and has to be taken in diet. The diet sources include red meat, fish, milk, poultry, yoghurt, eggs, fortified cereals, breads and other grain products. It can also be taken in the form of Vitamin B12 tablets or multivitamin pills. The deficiency of Vitamin B12 results in macrocytic anemia (size of red blood cells larger than normal).

Megaloblastic anemia is a type of macrocytic anemia, in which large size red blood cells called as macrocytes are produced. These red blood cells are fewer in number. There is a decrease in white blood cell count and platelet count. Megaloblastic anemia occurs due to acquired deficiency of Vitamin B12. The reason can be an inadequate dietary intake of Vitamin B12 or any problem in the absorption of Vitamin B12 from the intestines.

In case of problem in the absorption of Vitamin B12 from intestines, it is known as Pernicious anemia. It occurs due to lack of intrinsic factor which is present in secretions of the stomach.

Vitamin B12 is also important for nerve health and is taken as a nutritional supplement for the treatment of nerve damage.

Vitamin B12 binds with intrinsic factor (protein secreted by cells in the stomach). After binding, a complex is formed which is absorbed by the small intestine. In case of any disease interfering in this process can cause weakening of absorption of Vitamin B12.

Patient Concerns about Vitamin B12

Frequently Asked Questions about Vitamin B12

Q. How is this test performed?
This test is performed on a blood sample. A syringe with a fine needle attached is used to withdraw blood sample from a blood vessel in your arm generally from the inner side of the elbow area. The doctor, nurse or the phlebotomist will tie an elastic band around your arm which will help the blood vessels to swell with blood and hence makes it easier to withdraw blood. You may be asked to tightly clench your fist. Once the veins are clearly visible, the area is cleaned with an antiseptic solution and then the needle is inserted into the blood vessel to collect the sample. You may feel a tiny pinprick during the procedure. Blood sample once collected is then sent to the laboratory.
Q. Is there any risk associated with this test?
There is no risk associated with the test. However, as this test involves a needle prick to withdraw the blood sample, rarely, a patient may experience increased bleeding, hematoma (blood collection under the skin) formation, bruising or infection at the site of needle prick.
