Hi guys, I'm applying for permanent residency after a few years as 457 status and need to take the health examination. From reading it looks like they give you a chest xray, take blood and urine, check your sight and ask you about your medical history... please can anyone that has recently undergone the examination let me know if they do any other tests or take any other samples? Eg hair sample, anything 'invasive' etc etc. Don't really like such tests and I want to know exactly what I'm getting into before I turn up for the test. Thanks in advance. Ps I'm male.
