Unfixed tissue; Joint fluid

Unfixed tissue; Joint fluid
 

Hello everyone,
I am translating a medical document and in it talks about "unfixed tissue" as a potential infectious material, how do I translate that?
Also talks about "joint fluid" and don't know the spanish translation.
Thank you for your help.

Adrian

Welcome adrian
more context would be useful.
So said
unfiixed tissue: "tejido suelto", "tejido desprendido", can also be "tejido cortado"
joint fluid: "líquido articular" or "líquido de la articulación"
but I'm not an expert in this field. Ask Elaina ...
Saludos :D

Sosia's suggestions sound quite reasonable, but I'm not an expert in the field, so I don't have anything more to offer.

Thread moved to the vocabulary forum.

THank you much to both of you, it will help me a great deal.
Saludos

I've seen "joint fluid" usually translated as "líquido sinovial"
