Me...Nifty @ Dr Lau's clinics (early Feb 2013). Luckily, both are fine and 1-yr old now. Dr Lau called me on his own to tell the result. I remembered that it was still CNY holiday. I visited him again for structural checking. He is very professional and friendly.
There is no testing in the world which can tell 100% correct result. Over 99% is useful enough.
