What are some disadvantages and advantages of DNA microarray tests?

Answer 1

Advantages and disadvantages, microarrayAdvantages of DNA microarray tests include high throughput (lots of information with one test), and good coverage of the genome with the chips that have larger numbers of test spots.

Disadvantages include incomplete coverage, which can lead to false normal results, and the ability to test only for unbalanced rearrangements (duplications and deletions), and not balanced translocations or inversions.

However being high throughput and cost effective are the most elements for this technology, it still suffers lack of perfect processing methods and acceptable sensitivity as much as real time PCR
