After receiving the residence card you should receive the TB request from your Lege (Doctor). Because you need to undergo the said test within 3 months of stay here in Norge. So within 3 months you should receive the request. The name of the doctor ,hospital, date/time were all stated in the paper. and also you have a free bus ride going to the hospital you just have to show the paper to the bus driver. all the information and instructions are in the paper request.
hope this helps.
