Just fyi there's no such thing as a NIH guideline. You're just quoting a table in a very low impact journal. Pubmed is the central database where most publications are stored. Usually when a publication only makes it to a low impact journal, that's because there are significant flaws in the study.Every lab that runs these tests have slightly different results and their own reference range.It's somewhat futile to go on a endless journey for mildly abnormal tests because unless there's major clinical consequences, chances are it's nothing. As you said yourself, you're above the 97.5% but that means 2.5% of the population has hemoglobins higher than that which is you.Anyway good luck
15+ also above the 97.5 percentile for my gender and race according to the US National Institutes of Health.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4578165/table/T2/?report=objectonlyIm asking. If doctors dont trust the national institutes of health guidelines, what is the guideline I should expect them to use for abnormal?Do I need to be in the white male range for abnormal?Do I need to take iron supplements to pop my red blood cell counts into the abnormal for a white male range?
