Best Answer: You could take a DNA test (this is called an Avuncular Test) that would show if you where the aunt of the child. These test may not provide as strong of a result as a DNA paternity test. With avuncular tests there is a possibility of an inconclusive result.
When the alleged father is not available for testing, you can choose the sibling DNA test or the aunt/uncle DNA test. Both of these tests will give a probability percentage, and are not as conclusive as a paternity test. However, out of the two I would recommend the sibling DNA test.
