Hello from JustAnswer.

Although any number below the normal range is strictly speaking considered to be anemia, if the HGB and HCT were similarly just slightly below the normal range, then this is not significant.

This has to do with how we define the normal range for most labs. The normal range is defined two standard deviations above and below the average. If you have ever taken a statistics course, then you may recall that two standard deviations above and below the average will include 95% of the population. However, that also means that 5% of normal people will be outside the normal range. So, when we see lab results that are just outside the normal range, it is usually not worrisome.

So, yes, this would be considered to be anemia, by strict definition, but it is not a significant level of anemia and would only be worrisome if there are any other symptoms that would be consistent with a cause of anemia, such as bleeding.

If I can provide any additional information, please let me know.
