Need to half fill a test tube with ds's spit......:/

[hazeyjane]

It is for the DDD study, I can't for the life of me work out how I am going to get him to spit/dribble into the tube!

I've stopped his hyoscine in the hope it brings on a tidal wave of drool!

Any ideas?

He has had to do a wad sucking test before (that sentence looks very weird!) for mosaic Down's syndrome, it didn't go well and our lovely genetics nurse left very traumatised with a sample that was completely useless. Sitting next to a piece of banana sends him over the edge, so sticking wadding in his mouth was, mmmm, interesting!

He is clearly having a non drooly day today, so may wait for a dribblier day and follow him round.

I will try the blowing things - he is pretty bad at blowing and there is usually a lot of spit flying around when he tries!

Thanks zzzzz

No experience but how about playing 'pretending to brush teeth' with a dry toothbrush and then seeing if the brushing helps produce saliva and if he is able getting him to spit??

Doesn't need to be sterile if it is for genetic testing. Recorder might just work...

Could you make a game he would join in with? Both spitting and maybe a new medicine syringe to suck his up off the clean surface? Spit onto pictures maybe? Just hope not to start a bad habit lol

Sorry zzzzzzz. I can only assume that the person who spoke to you didn't realise. Spit isn't sterile anyway so seems a bit weird. Am I right in thinking that the sample was for array analysis for the DDD study and not some unusual diagnostic test?

For the DDD test our DD just had to chew on the sponge on end of a large cue tip that then got inserted and twisted into tube so all spit was in tube.

Maybe go back and ask them if they can help u with this?

I mean with the tube thing, as our DD would not voluntarily spit on command so we emphasised this to the geneticist and we were sent this item

I will ask the genetics nurse, sparkles, but tbh he was awful with the spongey thing on a stick thing when he had the mosaic downs test.

Since stopping the hyoscine, the drool has been building up, so I will try tomorrow.

Wish me luck!
