What happen if body contain high level of haemoglobin?
Nothing “happens” if you have a higher level of haemoglobin than average (normal). Haemoglobin only caries oxygen around the body in the red blood cells so a higher than normal level will help them to do this better. Athletes and mountaineers often have higher than average levels. If you have been found to have a high level with no obvious reason, the most likely explanations are an error in the blood collection or storage of sample, or dehydration. This should be checked by a repeat test before any other action is taken. Most repeat tests of unexpected abnormal results indicate that there was an error in the initial sample or that the “problem” has rectified itself. You do not say why the haemoglobin was being measured. This might be information that could help to answer the question more fully or accurately.
