Estradiol missing from baseline blood tests

[Observer]

Let's say someone gets a baseline with practically every blood test you could ever want pre-TRT, but they accidentally ended up with a standard estradiol rather than an ultrasensitive estradiol. Would it potentially come back to bite them if they don't follow up with another test to get an accurate baseline reading on estradiol? Of all the various blood markers, is that one okay to skip?
