Advice on urine collection with untrained child

[Guest guest]

Our doctor has ordered a urine neurotransmitter test for our son who is 3 and

not trained.

We have only done one other test, a porphyrin test, and it was a nightmare to

do. Is there

anything else other than those awful specimen bags? The test calls for no

liquids for 12 hours

prior, and then it must be the first urine after the " first morning urine.' How

does one

determine this? And without any liquids in him, how will it be possible to even

have a

sample to collect? Anyone have any suggestions for us on how to proceed,

methods of

collection etc...We need to figure this out before we have to do things like

regular urine toxic

metal testing. Thanks. Irene
