If a total testosterone lab comes back at 500.0ng/dl with a range of 15.0-648.0 ng/dl is that any different than a lab that comes back at 500.0 ng/dl with a range of 300-1100 ng/dl? In this example it would appear that a result of 100 ng/dl would be normal for one lab, but super low for another???? So 500 would be close to high for one lab but below halfway for the other????????
