Intrinsic Factor Antibodies Blood Test
Autoimmunity (1 Biomarker)
Special instructionsDo not take vitamin B12 supplements for two weeks prior to this test. If you are taking B12 supplements prescribed by your doctor you should ask them whether you should stop before testing.
This blood test identifies whether antibodies to intrinsic factor are present which would indicate pernicious anaemia, an autoimmune condition.
Pernicious anaemia causes a deficiency in vitamin B12, an essential water-soluble vitamin found in virtually all meat products and certain algae such as seaweed. It helps maintain healthy nerve cells and red blood cells and is also required to make DNA, the genetic material in all cells. Symptoms of pernicious anaemia include, fatigue, shortness of breath, brittle nails, pins and needles and cognitive difficulties (brain fog). Symptoms of pernicious anaemia can become debilitating and can cause lasting damage if not caught early enough. Pernicious anaemia can be treated by regular vitamin B12 injections.
