With the lab: Normal ranges are created by the labs doing the tests. The methods used to test hormones can be different and so can the average ranges. The ranges are frequently based on the labs employees donating blood for analysis!

Lab reference ranges: Levels of these hormones are only as reliable as their test kits. One lab may use a different method for detection than another. You may not be able to compare values between different labs. Labs also set their normal ranges based on multiple tests. You need to discuss these hormones with an endocrinologist as they're trained to understand the different testing methods.
