Brief Answer:
It is a good sign and means enough saliva was put on the strip!

Detailed Answer:
Hi and thank you so much for this query.

This actually means that enough saliva has been put on the collection sponge to allow for appropriate testing. It is not a bad sign and you should be okay with this.

I hope this helps. I wish you well. Feel free to ask for more information and clarifications if need be. Above all, thanks for using our services.
