Brief Answer:

Detailed Answer:
I would be glad but kindly provide the reference ranges on the laboratory report. Endocrine labs are unique in that there is no standard reference range as is the case with many other types of lab tests such as CBC for example. Each lab reports specific reference ranges for normal depending on the type of testing method ('assay') they use.

Detailed Answer:
Generally, these laboratory results are considered normal. Medicine is not just a science of numbers so an in-person examination of the individual is necessary to pronounce the thyroid status of that person as normal.
But on face value, these appear to be well within normal range.
