Response to Eggs
It appears there are at least three different standards still being used to measure AMH. From a recent article in Reproductive Biomedicine Online entitled "The journey from the old to the new AMH assay: how to avoid getting lost in the values":
"To date half of the published articles have used the Diagnostic Systems Lab (DSL) assay and the other half the Immunotech (IOT) assay. Unfortunately, these assays utilize two different primary antibodies against AMH and different standards, and consequently the crude values reported can differ substantially, with the IOT assay giving values for AMH that are higher than those obtained with the DSL assay. With the recent consolidation of these two companies by Beckman Coulter, and their sole ownership of the patent to measure mammalian AMH, there is finally a single commercially available assay the AMH Gen II assay, which will fully replace the DSL and IOT assays"
Confusing enough?? Since this was only published last year, I'm sure there are still plenty of different assays in use... So, the assay my clinic uses is this:
High: Over 3.0ng/ml
Normal: Over 1.0ng/ml
Low Normal: 0.7-0.9ng/ml
Very low: Less than 0.3ng/ml
If you're being told that 1.4 is low, than it's probably a different assay. 1.4 was my donor's level and she just gave us 26 eggs, so that's why I was surprised!
Regardless, I'm so sorry you're going through this. I have a lot more to say, but I'll save it for a different post.
