Hi brm,
Your questioning of the reference ranges is nothing less than understandable.
Of course I cannot comment on your situation specifically, just generally as I am not aware of the nature of the tests that you had.
What I can say is that differing hospitals use differing techniques for assays/tests, having differing levels of sensitivities and equipment calibrations and this often accounts for differing results found.
What is important is that the reference ranges for any given test are based around these individual tests/sensitivities/calibrations etc.
Without the correct accompanying reference ranges it is impossible to correctly interpret the nature of the test results themselves.
Differing methodologies can also be a factor when looking at test results, this is particularly true when there appears on the face of it bizarre discrepancies in the expected results, results that on the face of it do not seem to make sense.
The above accounts mostly for the confusion of the lay person/patient in trying to interpret their test results.
Of course tests are also open to error, some more so than others and doctors too are capable of misinterpreting their results. In fact there are many ways of misinterpreting results.
Last of all a top endocrinologist will understand the limitations of blood pathology and will understand the need not to rely on them exclusively, but rather to use them as a tool or guide in combination with symptomatology and examination in order to arrive at a correct diagnosis.
This last point is a very important one- I have detailed the problems that occur when doctors strictly interpret pathology to the exclusion of symptoms in my second post in the thread below.

The bottom line is a good endocrinologist who has an active interest in reproductive endocrinology, a doctor who has studied and qualified in the study of hormones is best placed to investigate these matters and arrive at a correct diagnosis.
Like I say it is better to be safe than sorry.
The majority of people will simply be told that they are well and that their gynecomastia has no underlying cause; that is a statistical reality.
But there is a significant minority who do have underlying causative factors that require diagnosis and treatment and for those people it is important to get the correct diagnosis.
And of course no one knows what boat they are in until they have had their situation covered via a consultation.
See an endo have your gynecomastia checked out, then IF you wish for it to be removed see a surgeon- in that order.
