Hi Laura,
I take the freedom to move your email reply back to the forum so everybody can benefit from our discussion.
Hi Kerstin,As far as I can tell, you have re-pasted the original question.
When you say several protocols, can you be more specific as to which protocol you are using and what the protocol is?
If
not, then I can write up a bunch of different scenarios for all the
possible protocols. Maybe I should I interpret your response that this
is what you
are meaning.
My answer:
The commonality of the "several protocols" is described in the question stem: "... recommend first obtaining a plasma
D-Dimer level, which is a measure of increased clotting activity in the blood,
and then obtaining a CTPA for patients with a D-Dimer level ≥ some
threshold. "
Yes, you can make up any protocol that meets these criteria!
Best,
Kerstin
