CBE with week's estimator- FDA data

[NariaDreaming]

If anyone else wants to obsess over hcG levels and the CBE weeks estimator tests, you'll probably find this fascinating:

I'm not a scientist, but their thresholds seem low to me.

I'm curious about this, but I can't decipher this well enough to obsess over it. Cliff's notes, anyone?

They're crazy sensitive. And the weeks ranges are bullshit.

I wish all cliffs notes were this straightforward.

So is that saying it is sensitive to below 50mlu? I always thought it was 50- I got my BFP at 9dpo on an frer and kept seeing the line darken every 12 hours or so, but I didn't get a pos 1-2 until 12dpo I thought that meant that I had just hit the 50mlu that day..

I'll put it to you like this- I used it the day after my beta was a 19, and got a positive

So reading this am I right to assume if you get 3+ you are definitely at least 2500, but you could be quite higher and still register 2-3?
