There are ways of ensuring the test even further with gold test needles which will react to the acid the same way as the test sample.

Another method is the hand held electronic gold testers, which give a good indication of what karat the gold is. and the most accurate method of determination is the xrf machine, which in addition to telling you the gold content will tell you the content and percentages of other metals present in the sample being tested.
