Well update is...went for $200 respitory test yesterday, doctor listened to lungs, confirmed that the x-ray showed scaring which is down to operation 55 years ago, x-ray explained and cleared, just need to do sputum test which is required by immigration - all good..not so quickly, just before we were ready to leave, doc then says to do another x-ray in 3 months then come back and see him directly 10 days after (guess a further $200 for 20 mins) I explain that my mum goes home end of October so that won't be possible - he says just get it done when she comes back!! When I question why another x-ray is needed he just said immigration requires it. I walked out very confused and sent immigration an email this morning for clarification as it all sounded strange to me. My mums scar will still show on a x-ray in 3 months, 3 years, 30 years time?
