urine sample

[filthiestfis]

I have to give a urine sample for a checkup, does it have to be taken first thing in the morning?

Yes usually also you usually need to fast overnight

it usually has to be MSU - (mid sample urine) as in start then stop - then fill the bottle...

what?

Do a bit of wee first, catch the next bit for your sample then finish your wee.

The GP/nurse/Dr would usually say if it has to be the first pee of the day. If they said nothing it generally means anytime. Mid stream wee is only on certain cases (pregnancy/gyny probs are just two examples of this) but not always the case though!!



If it was necessary to fast for 12hrs before the sample is taken, then you would have been told as such. Taking blood to check for cholesterol levels requires this strict practice. i.e if the blood is taken at 9.00 am then you must not drink or eat (anything) after 9.00 pm the previous evening. As I said before you would have been told if this was the case.

Having said that :
Err on the side of caution - and use the first pee of the day as it is more concentrated, and will give a better indication of any problems (or not).

Thanks for your answers

For certain things (eg urinary infections) it also needs to be taken as close to the time of the checkup as possible in case it changes over time
