You don’t need blood to determine the absorbency of the products. We do in fact have a very clear idea how much more viscous blood is compared to water and adjust for that.
The people who are complaining about this I suspect have very little experience lab sciences.

I’m sitting between my hplc and gcms, if you think pH and acidity (both carefully controlled for by the body) have nothing to do with absorption you might have very little experience with lab sciences.
It’s about much more than viscosity, it’s about evaporation rate, chemical balance, and yes some absorbency. I would say just using generic human blood isn’t enough, the chemistry within the vagina is self regulated like no other part of the human body, it’s kinda the key organ to life’s continuance.

As the only real goal of tampons and pads is to absorb the discharged fluids and prevent their transfer to clothes and skin. Unless there is a rampant problem of menstrual products not working I fail to see how this is a problem.
If you actually work in a lab you should know how much more expensive using biohazards to test would be.

Yes I actually work in a lab, recycling/waste disposal is something we work into our budget. You think they aren’t funded well enough to afford those expenses?
Question my credentials again, please, it amuses me.

You don’t think it costs more to do?
Are you completely unaware of how business works?
There’s no way to prove your credentials and frankly I would not be inclined to believe you at all.
