B12
This test is done to test how much B12 is in your blood. This test is most often done when other blood test tests suggest a condition called megaloblastic anemia. Pernicious anemia is a form of megaloblastic anemia caused by poor vitamin B12 absorption. This can occur when the stomach makes less of the substance the body needs to properly absorb vitamin B12.
Your doctor may also order a Vitamin B12 test if you have certain nervous system symptoms. Low levels of B12 can cause numbness or tingling in the arms and legs, weak.
Folic acid
A folic acid test measures the amount of folic acid in the blood. Folic acid is one of many B vitamins. The body needs folic acid to make red blood cells (RBC), white blood cells (WBC), platelets, and for normal growth. Folic acid also is important for the normal development of a baby (fetus).

Folic acid can also be measured as the amount in the red blood cells. This test may be a better way than the plasma test to measure the amount of folic acid stored in the body. The amount of folic acid in red blood cells measures the level when the cell was made, as much as 2 months earlier. This level is not usually affected by the amount of folic acid in your diet each day. It is a more accurate way to measure the body's level of folic acid.
Reticulocyte Count
A blood test that measures how fast red blood cells called reticulocytes are made by the bone marrow and released into the blood.
