E2 Test Type: Standard or Sensitive?

Does it matter what type e2 test you take? I know a lot of trt guys say to only use the sensitive but others who say the sensitive gives you a lower e2 reading than you really have. So is the typical 20-30 range good for the standard e2 test it only the sensitive? Any input would be great! Thanks

The problem is mostly confined to labs from Quest Diagnostics.
The debate goes back years. And yes, you can get different results.

The standard test at Labcorp works well.
