Lifelabs estradiol test

[Jabbathehutt]

Hey guys,

I have a question on the estradiol test from lifelabs. Under the estradiol result there's a note that's says the following:
"Estrogen receptor antagonists and aromatase inhibitors have been shown to interfere with estradiol testing by some immunoassay technologies resulting in falsely elevated estradiol concentrations. For patients taking these medications, please interprete results with caution"

So it basically means that if you are taking an AI that test won't work at all?

Thanks

Yes, because AI’s will cause low E2 levels making the test not accurate and in turn will show falsely elevated levels.

Then how do test E2 in BC? There's only lifelabs here

Uhhhh what lol.

That specific test is not accurate in measuring lower levels. AI’s can put you in lower levels. So the number it spits out will most likely be higher.

 

[Jabbathehutt]

How much higher?

How much higher?

I’m not sure of the testing methods used above most likely ELISA. I seen blood results posted where someone got both LC-MS/MS and ELISA done at the same time. The results were not close. I can’t remember the exact difference but I think it was around 30 pg/ml (8-35)

Oh ok! I misunderstood you. My mistake
