The immune system produces certain proteins called Intrinsic factor Antibody. And these proteins are connected with pernicious anemia.
The test measures the Intrinsic factor Antibody that circulates in the blood.
Vitamin B12 is released by the stomach acids from food during digestion to form a complex of intrinsic factor. This process is necessary for vitamin B12 to get absorbed easily by the small intestine.
When there is a lack of intrinsic factor in the body it leads to pernicious anemia.
If your test results show a low level of Vitamin B12, you are likely to be suffering from pernicious anemia.
Accordingly, the doctor will give you medications.
Test Method 1: A blood sample will be collected from a vein of your arm. You will be given a Vitamin B12 injection 48 hours before the test.
In some cases after receiving the injection, you might be called to get the blood test done after 2 weeks.
Test Report: The usual turn around time is 24 to 48 hours.
If your doctor suspects you of suffering from the symptoms of pernicious anemia, you will be prescribed to get this test done.
