Is there a Visco Elastic Test for Doac?

There's limited evidence that the visco elastic tests measure factor ten inhibiters in a reliable way. I'm really intrigued some of the the newer experimental assays that romans discussing as an agonist. They're using an icelit from the russell viper, which is, i believe, a south asian venomous cobra. And that particular toxin specifically activates factor ten and maximmly activates it. But we're not, we're not there yet.
