Blood tests check for levels of haemoglobin, the size of red blood cells, vitamin B12 levels, and folate.
Further blood tests check for pernicious anaemia, where the immune system attacks the parietal cells in the stomach, meaning the protein intrinsic factor cannot be made.
“Tests for pernicious anaemia are not always conclusive, but can often give your GP a good idea of whether you have the condition,” the NHS stated.
People diagnosed with pernicious anaemia will usually be treated with injections of hydroxocobalamin.
