How long do DNA test take?

How much time does it take to get a single DNA test done? How it is done?

• Like whether two DNA samples match, whether there is a familial connection etc. Please discuss how the test is done in basic terms. I frequently see test results obtained rather quickly in movies, TV shows. What is realistic duration of the procedure?

• Answer:

  there are few startups who do that on commercial front like 23andme (weird name though it's named after 23 pairs of chromosomes in humans) in a month's time I think & charge some 99$ (it used to be 1000+ when they started). whole idea is to create a genepool data across population to identify likelihood of hereditary defects. 23andme recently received 50M in seed funding @http://techcrunch.com/2012/12/11/23andnotme/ and has enough credibility as it's backed by google's sergey brin's spouse http://en.wikipedia.org/wiki/Anne_Wojcicki,
