Hi I have a question. Do lab results vary depending on the lab doing it? For instance, for E2, quest diagnostics has a reference range of <29 being normal. But others have 20-30 being normal. So my e2 of 7 is normal for my test because it was quest, but abnormal for a different one. Does this mean the "7" would show up no matter who I used, or can it be different depending on the lab?
